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.
  1. If any other DTCs are set, perform those diagnostics first.
  2. 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.
