Good
- Check ECM, IGPM (CGW), SCC (FCA) 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/short in harness.
- Repair as necessary and then go to "VERIFICATION OF REPAIR " procedure.
