Useful checks before replacing parts
- Check network voltage, termination where applicable, shifter module power and grounds, connector condition, and short-to-ground faults.
- Verify whether the gear shift module communicates with a scan tool and whether selector position data reaches other modules.
- Inspect console harness routing, water intrusion, damaged network wires, and aftermarket equipment tied into the same circuits.
