    • Repair any CAN related DTCs first and then carefully re-do this troubleshooting guide steps.

Thoroughly check terminal of battery, all connectors (and connections) for looseness, bending, corrosion, contamination, deterioration, and/or damage.
    • Repair or replace as necessary and then go to "Verification of Vehicle Repair " procedure.
