Good
- Check telltale lamp and 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 airbag fuse, passenger compartment junction block, harness between junction block and SRSCM. Repair as necessary and go to "Verification Of Repair " procedure.
