Signal Missing
Signal missing
Checking the component and wiring
Hint: If the diagnostic trouble code (DTC) for the gear-shift position sensor is stored in the transmission control module (TCM), this diagnostic trouble code (DTC) must be remedied first.
- Check the connector for the transmission control module (TCM) control module. Check for contact resistance. Check for oxidation.
Check the signal cable between engine control module (ECM) terminal #B15 (#C15) and transmission control module (TCM) terminal #5. Check for an open-circuit. Check for a short-circuit to supply voltage. Check for a short-circuit to ground.
Remedy as necessary.

- Ignition off
- Reinstall the connectors, components etc.
- Gear selector in position P or N
- Ignition on.
Read off the values for the gear selector position.
Directly connected signals and signals via CAN communication must correspond to each other and to the selected gear position when the gear selector is in P or N.
Are the values correct?
Yes - VERIFIED
