Good
- Check ECM, ICU (CGW), SCC/FCA module connectors for looseness, poor connection, bending, corrosion, contamination, deterioration, or damage. Repair or replace as necessary and then Go to "VERIFICATION OF REPAIR " procedure.
No Good
- Check for open or short in harness.
- Repair as necessary and then Go to "VERIFICATION OF REPAIR " procedure.
