Service Vehicle Soon Light

There are a few possibilities that are available. Are the chime and the SVS light seemingly unrelated meaning, you could have one and not the other. And with the chime, are there any indicators that come with it? Here is the description and operation of audible warnings.

Audible Warnings Description and Operation
The audible warnings alert the driver of a system concern or a critical vehicle condition. The radio generates the audible warnings. The BCM receives audible warning requests via the class 2 serial data line or the controller area network (CAN) data line. If the BCM receives multiple audible warning requests, the warning with the highest priority sounds first. The following lists the audible warning priority and the pulse rate:

Fast rate chime--200 pulses per minute
Medium rate chime--150 pulses per minute
Slow rate chime--50 pulses per minute
Single chime
Fasten Safety Belt Warning
The body control module (BCM) activates the fasten safety belt audible warning as requested by the sensing and diagnostic module (SDM). The SDM sends a class 2 message to the BCM. The fasten safety belt warning sounds and the fasten safety belt indicator illuminates when the following occurs:

• The ignition switch transitions to ON.

• The inflatable restraint SDM detects that the driver seat belt is not buckled and or the signal is low. The BCM receives a class 2 message from the SDM indicating the driver seat belt status.

If the seat belt is buckled when the ignition is turned ON, the chime does not sound. If the seat belt is buckled while the chime is sounding, the chime stops. If the seat belt is unbuckled after the initial transition to ON, the chime does not sound.

Key in Ignition Warning
The BCM monitors the signal circuit of the ignition switch. The BCM activates the key-in-ignition audible warning. The key-in-ignition warning sounds when the following occurs:

• The ignition switch is OFF.

• The BCM determines that the driver door is open and the signal circuit is low.

• The BCM determines that the key-in-ignition switch is closed and the signal circuit is low.

Lights On Warning
The BCM activates the lights on warning. The radio chimes a frequency of a fast rate and a continuous duration. The lights on warning sounds when the following occurs:

• The ignition is OFF.

• The BCM determines that the driver door is open and the signal circuit is low.

• The BCM determines that the headlamp switch is in the park or head position.

Park Brake Warning
The BCM activates the park brake audible warning. The park brake warning sounds and the BRAKE indicator illuminates when the following occurs:

• The ignition is ON.

• The vehicle speed is greater than 5 km/h (3.1 mph). The BCM receives a CAN serial message from the ECM indicating the vehicle speed.

• The BCM determines that the park brake is engaged and the signal circuit is low.

With the SVS light, did the dealer mention any trouble codes? There is a bulletin that may apply, it has a VIN breakpoint that you will have to check to determine eligibility. It is as follows.
#PIT3633A: Intermittent Service Vehicle Soon (SVS) Light Comes On - keywords BCM calibration cluster control DTC module power speed SVS - (Jun 27, 2006)


Subject: Intermittent Service Vehicle Soon (SVS) Light Comes On


Models: 2005 Chevrolet Equinox

Built prior to VIN Breakpoint 56171611




--------------------------------------------------------------------------------

This PI has been reinstated due to a high volume of calls to Technical Assistance.


--------------------------------------------------------------------------------

The following diagnosis might be helpful if the vehicle exhibits the symptom(s) described in this PI.

Condition/Concern:
Intermittently the Service Vehicle Soon light may illuminate with no codes, or only a history DTC C0000 stored in the Power Steering Control Module (PSCM). The Service Vehicle Soon (SVS) light can be identified by a picture of a car with a wrench in it. For vehicles built prior to VIN break point 56171611, the SVS may illuminate after the bulb check and remain illuminated until the ignition key is turned off. The following information DOES NOT apply to the Service Engine Soon (SES) light.

Recommendation/Instructions:
If ALL of the following criteria are met, follow the repair instructions below.

No codes current or history set in any module or only a C0000 found as a history code in the Power Steering Control Module (refer to Service Bulletin 04-08-47-001 regarding C0000).
There are no concerns about erratic steering feel (heavier/lighter than normal).
There are no concerns about an erratic speedometer needle.
If the concern is "The SVS light came on when the vehicle was started and stayed on after the bulb check until the ignition was turned off". This is not an intermittent illumination "during" a key cycle.
Note: If any of the above conditions are not met, it will be necessary to perform further diagnosis per SI, since other issues may be present.

If ALL of the above Conditions are met, then replace the Instrument Panel Cluster (IPC). The following parts can only be obtained through an Electronic Service Center (ESC).

Part Numbers:

15289974 (US)

15289975 (Canada/Mexico)

Please follow this diagnostic or repair process thoroughly and complete each step. If the condition exhibited is resolved without completing every step, the remaining steps do not need to be performed.

Of course if there was any trouble codes, those would need to be known, and could have some relevance in the light, and possibly the chime depending.

Your information about the SVS light was right on the money! That describes my vehicle's "behavior" exactly! The dealer kept telling me there were no codes in the car's system. He said he checked two types of codes, one I remember was engine codes and I don't recall what he said the other ones were. Thank you!

As for the chime, it only comes from one speaker (front passenger side) and if it is dinging and I turn the radio on, that side will continue to ding and the radio will only come out of the driver's side.
The sound is intermittent, and I would say it is a slow ding. It will last anywhere from about 5 minutes to as long as 20 minutes. At times, I have come out to my car to drive it and approaching the car I can hear it ding. When I am driving it, at times it will start dinging, it is a slow, almost methodicaly ding sound and it will get softer and sometimes even pause before continuing to ding. It never gets extremely loud, but it drives me crazy!!!

And yes, I often have one without the other. I have owned the Equinox 2 months now and I have heard it do it's "dinging thing" 5 times, it may have done it other times when I wasn't in the car =) I have not had both of the problems together... yet.

All my dash lights work. When I leave my key in the ignition I will get the same ding sound but from the driver's side speaker not the passenger side speaker. The passenger side speaker only gives me the turn signals sound and this random dinging sound.

Your help is so appreciated! Thank you!!!

The fact that the passenger side speaker is making noise, is what is puzzling. Here is the circuit description under chime malfunction;The radio generates the audible warning through the left speaker. The radio receives audible warning requests via the serial data circuit from the instrument panel cluster (IPC) or the body control module (BCM). Did the dealer research for any possible software calibration upgrades that might address. I would think that it may be a possible software issue, The other two possibilities are a fault in the radio, or body control module. At some point maybe the system thinks the vehicle is RH drive(Export Option). When you reply, include the full 17 digit VIN, and I can research a possible calibration that may address this, it will save you a trip to the dealer.

Your help is so appreciated!
The Equinox's VIN is: 2CNDL23FX56123254

I don't know if the problem is with the radio, I had thought of that as a possibilty. I am getting ready to purchase a new wiring harness for a radio I had in my old vehicle that I sold to purchase the Equinox. The wiring harness is way overpriced because the "car sounds" come through the speakers not the engine. I intend to get the radio switched out in the next month or so.

The dealer just emailed me and wants me to bring the Equinox by so he can try to pull codes from the engine. I will have time later this week to get it over there.
Thank you!

There is no software calibration upgrades to address your symptoms. I would not suspect the radio, it is just a medium to transfer the request to the speakers. Has anyone been able to duplicate this with a scan tool installed, I would think monitoring inputs/outputs in the IPC or BCM. If you are opting for replacement of the IPC in regards to the SVS concern, you would eliminate that module itself as a possibility.

My check engine light come on today. I filled up with gas (87 octane) early this morning (around 12:00 noon) no problems... ran my errands until about 3:30. I went to the store for a minute; as I was leaving the store cranked the car up, my light came on. The car did not run hot the entire time I was running my errands, I checked the gas cap to make sure that it was secure, it was.... could you please advise as to what the problem could be?

Thank you

You need to find the codes from the computer to start diagnosing this. It is something to do with emissions.

Here is a guide to help us get started

Please run down this guide and report back.

I replaced the oxygen sensor for a $104.00 fixed it

My check engine light comes on sometimes for a few days and then goes off for a few days.
Can I reset this myself?
The car runs great and we have service preformed on a regular basis. Oil every 3,000 is changed.

The CEL shoudn't be coming On and Off -you have a problem, get the computer scanned for code/s to find out what's going on.

My engine light just went on yesterday. I see nothing wrong. What could it be?

I would start by taking it to a auto part's store like auto zone and have your car scanned for code's.It could be something as simple as a loose gas cap.When you get the code number let me know and i will help you out with that.

The engine light is on ,how do I get it to go off. I have tryed changing out the gas cap but that was no help.

Have the computer scanned for code/s-you have a problem within the engine management system that caused the CEL to turn on-This is your starting point of diagnosis,finding out what's going on.

vin. 2cnd173f966155806. #1 code po120, #2 code po700, #3 code p1125, #4 code p2138, codes were ck,ed cleared car run for 1 day lite back on, if we shut car off abd restart maybe ok. went to gm dealer, could not find any thing. it is just like you shut down the gas,boggs, in reverse it is ok. any ideas???? thanks conrad.

check the instrument panel/body inline connector for bent or corroded terminals,its behind the left hinge pillar garnish molding.start there.

I have replaced all the equipment that the Check engine codes said were bad and the check engine light came back on with the same codes Any help would appreciated

No diagnostic fault codes ever say to replace parts or that they're bad. They only indicate the circuit or system that needs further diagnosis, or the unacceptable operating condition. First your mechanic will perform electrical tests on the circuit to rule out wiring and mechanical problems before spending your money on parts.

If you want to know how to diagnose a fault code, it would make it a lot easier if you would list which codes you're getting. There's well over 2,000 potential fault codes, so it doesn't pay to guess.

I have a 05 equinox Check engine light was on had mschanic replace egr m o2 sensors and then the light was off came back on with the same codes Took back to mechanis He says it needs to be reflashed at dealer and now it stalls when putting it in gear

You need to tell me the exact fault code numbers, otherwise there's nothing I can do for you over a computer. Without those numbers, I can only offer the generalization in the first paragraph of my previous reply. If it's a code number I'm familiar with, I can give you the list of troubleshooting steps to rule out everything other than a part referenced in the code. When a sensor or other part is mentioned in a code, there's a lot of other things to check before buying a part. The only time we throw a new part at a problem is if it's a known common problem, or we have the part in stock already, so it doesn't cost us or the customer anything to pop it in and try it.

my OBDII trouble code reader is having a link error so i cant figure out why my check engine light is on.

your scan tool may not be compatible with your vehicle, try using a different style OBDII reader

GM Right now the check engine light is out which I guess is a good sign, But the Nox Stalls when put in gear and then hard to get it started, I can start it and it will idle May even drive for a little bit then will stall and then does not start Tries to but just dies

I had the same problem and called the obd2 manufacturer, they said some cars are not compatible with the older model obd2 tools, it worked with another model at autozone, they do it for free, so now I use them for this car only instead of buying another tool

Hi-
My car has been idling (?sp) a little rough for the last few weeks, but I was going to wait until I visited my folks in a couple of weeks to have the car checked by a mechanic because my dad's close friend is a mechanic and won't take advantage of me. Yesterday morning on my way to work (about a 7 mile drive) my check engine light came on. This morning, the car acted like it didn't want to start when I first turned the key over. And then, when it started, the check engine light came back on and even blinked at one point. The oil was changed less than a month ago and I've had the coolant level checked as well. The idling (again, ?sp) seems a little worse earlier in the day. Everything else seems to be working fine and I've had essentially no problems at all from the car. Your help would be greatly appreciated.

If the light came on, that means the computer has picked up on an electrical problem with in the system. What I need you to do is this. Take the car to a nationally recognized parts store and have them scan the computer for codes. Most will do it for free. Have them write the trouble code numbers down on paper for you and let me know what they are.

NOTE: If they try to sell you something, wait until we speak again.

Interior problem
2005 Chevy Equinox 6 cyl Two Wheel Drive Automatic 65. miles

hello, a yellow sensor light came on in the dashboard ,,its a yello light with the truck in it , with a wrench through it please let me know what this means

That is a check engine light. Take the vehicle to a nationally recognized parts store and have them scan it for codes. Most will do it for free so there is no money out of pocket.

Let me know what you find.

Hi my 2005 Chevy Equinox broke down yesterday.
Here are the symptoms:
1) While driving the truck hiccups (i've been driving it this way for awhile)
2) The check engine light came on yesterday
3) The engine had no power could not get it to rev above 2000rpms
4) I shut the truck off to wait for towtruck and then tried to restart it but it would only
turn over then shut itself off immediately.
I really hope you can help me figure this out.......thanks :)

That's like diagnosing an illness over the phone. There are dozens of possibilities but GM does have a lot of trouble with their fuel pumps quitting while driving. That leaves you stranded on the side of the road. Chrysler pumps by comparison almost never do that. When they wear out they fail to start up but once they're running, they keep going. That leaves you stranded in your driveway or at work, at least not in the country on the side of the road in a puddle of tears. Both of those "pattern" failures are common enough that they are the places to start looking. Your mechanic will perform some diagnostic tests to determine if fuel pressure, spark, or some other cause led to the stalling.
