Good
- Check PCM/TCM, ICU (CGW), SCC module connectors for looseness, poor connection, bending, corrosion, contamination, deterioration, or damage. Repair or replace as necessary and then go to "System Inspection " procedure.
No Good
- Check for open or short in harness.
- Repair as necessary and then go to "Verification of Repair " procedure.
