Inspection Procedure
HINT:
- The following troubleshooting procedure is based on the premise that the engine is cranked normally.
If the engine does not crank, proceed to the Problem Symptoms Table. Refer to PROBLEM SYMPTOMS TABLE .
- Read freeze frame data using the Techstream. The ECM records vehicle and driving condition information as freeze frame data the moment a DTC is stored. When troubleshooting, freeze frame data can help determine if the vehicle was moving or stationary, if the engine was warmed up or not, if the air fuel ratio was lean or rich, and other data from the time the malfunction occurred.
