Inspection Procedure

HINT: 

• Various systems use the vehicle speed signal distributed from the combination meter. Check all the components possibly related to speed signal.
• Read freeze frame data using 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 be helpful in determining whether the vehicle was running or stopped, whether the engine was warmed up or not, whether the air/fuel ratio was lean or rich, as well as other data recorded at the time of a malfunction. Refer to FREEZE FRAME DATA .
