Circuit/System Verification
IMPORTANT:
Disregard any transmission symptoms, antilock brake system (ABS) indicators, and traction control system (TCS) indicators until any fuel trim faults are repaired. A fuel trim fault may cause default actions such as harsh shifts and illumination of the ABS/TCS indicators.
- If any other DTCs are set, perform those diagnostics first.
- Operate the vehicle within the parameters described in Conditions for Running and Conditions for Setting. The DTC should not set this ignition.
- If the DTC sets this ignition, proceed with Circuit/System Testing.
