Where is the Immobilizer control unit located?

Hi ANDRIN,

Without the smart key system, the immobilizer is located at the left side the dash by the steering column. Check out the images (below). Let us know if you need anything else.

Thanks Ken, so what do I have to remove before getting to it. Yes this is without smart key. Diagram as well for the wiring.

I appreciate your fast response

You are welcome, yep, you will need to remove the steering column. I did find a better image of the unit though. Here are the wiring diagrams as well.

Found it Ken, thanks! Actually I am getting no immo light on dash when even key is in run position. Can you help me with the pin out signals on the immo ecu?

I need to find out what or who is responsible for turning the immo security on dashboard .

The PCM is responsible for turning on the security light. I would run the codes with a CAN scanner to see what codes are stored.

This video will show you how.

I can’t remember the exact code, but it did mention Smarttra open circuit or short circuit. The ECU responsible for turning the security light in dash, looking at the diagram you sent, could it be the blue cable living the junction fuse box to the ecu than enabled the ecu turn in the light?

The immobilizer unit does not have a can arear network

I would double check the "room LP" and "audio" fuses in the fuse panel inside the car.

The room lamp is find and the audio as well, when I check the diagram I saw the line for the room lamp and audio including the immo, it’s all good.

What I actually suspect is the line that turns in the Immo, if you look closely the diagram you sent. So I was wondering I I have the ecu pinout and I could locate this line and feed it with signal and see if the light turns on on run position.

Sure, here it is, check out the images (below). Let us know what you find.

You got it right Ken, this must be the line that is open or short to ground, because that was the report I got from my scan tool. I will use a multimeter to check for continuity, am sure the line must be open. A million thanks Ken.

No problem Andrin, I hope it is just a wiring issue.

I know so, I will update you with the results. Thanks I truly appreciate.

Please Ken, may I have the connector images and the images of both connectors of the ecu and the dashboard?

Am currently working on the car today.

What actually I need is the diagram of the connector which goes to the dashboard. So I can trace the orange of brown cable for open or short circuit

This is the connector to the instrument cluster, the orange and brown wire leaves the ecu into the instrument cluster

From the diagram, the wire on the ecu 69 to the instrument cluster is 13, but when I verify the connector I can’t find orange and brown on this position. If I can have a clear map on this orange and brown enough.

Following your diagram, this anti theft system is in the bcm to the pcm or from the pcm to the instrument cluster

Which of the anti theft system does it leave the pcm to? Referring the orange and brown wire.

Only the brown/org and green wire go to the cluster.

Thanks Ken, you have been super supportive. Problem solved. That connector to instrument cluster, I noticed a short on 13 pin, so I had to cut it, then the key light showed with key on run position. Later I reconnected the wire and the light stayed on and kick the car and it started.

The wire I marked in red was shorting, because I ran a continuity with a multimeter and noticed the bit was shorted to ground.

Just as the fault code described

Nice work getting the problem solved! Come back anytime.

Thanks men
