No crank, no start, transmission gear selector stuck in p and multiple codes

Hi,

You have your hands full with this one. I reviewed the codes and the one that stands out is the P0500. That is indicating a breakdown in the CAN bus system. I would suggest checking total resistance in the under hood can system. I have a feeling there is an open circuit.

Here are the directions for testing. The attached pic correlates with the directions.

- X63/4 (CAN databus adapter connector, 2-pin)

Test sequence
- Switch off ignition
- Measurement with multimeter
- (X63/4) 2.22.1 (X63/4)
- Adapter cable no. W220 589 00 99 36 may be used.

Specified value
- [55...65] ohms

Question: Is the measured value within the specified value range?

No
- The measured value is not o.k.
Possible cause and remedy
- Cable from component N3/10 (ME-SFI control module) to component X63/4 (CAN databus adapter connector, 2-pin)
- Test terminating resistor of component X63/4 (CAN databus adapter connector, 2-pin).
- Test terminating resistor of CAN element in control module N3/10 (ME-SFI control module).
**End of test**

Yes
- The measured value is o.k.
**End of test**

Let me know what you find.

After days of tracing the problem, I shook the wires running under the trim (left hand side) at the CAN adapter connector, then the gear selector could move out of p and the car started.
Thank you so much.

Hi,

Glad to hear it's running. Was the connector loose or corroded? Regardless, glad it's running.

Let me know.
Joe

It was corroded.
Thank you one more time.

You are very welcome. Take care of yourself and please feel free to come back anytime in the future if you have questions.

Take care,
Joe
