Replacing A Component
CAUTION:
Avoid touching the pins in the control module and the corresponding connector on the cable harness.
There is a risk of static discharge which could damage the control module.
Discharge yourself and tools to be used by holding the tool's metal part and touching a body part on the car just before starting to work.
If voltage is approximately 0 V on terminal #B15 on the Engine Control Module (ECM), when the gear-shift position sensor is in position P or N, the circuit for the gear-shift position sensor is working.
The fault may be in the Engine Control Module (ECM).
Try replacing Engine Control Module (ECM).
NOTE:
Before replacing the control module, ensure that all other relevant symptom tests have been carried out.
