Good
- Check terminal of battery, all connectors (and connections) for looseness, bending, corrosion, contamination, deterioration, and/or damage.
- Repair or replace TCM or ICU as necessary and then go to "Verification Of Repair " procedure.
No Good
- Repair open or short in circuit and then go to "Verification Of Repair " procedure.
