Inspection Procedure

HINT: 

• If DTCs relating to different systems which share terminal EIA1 as their ground are stored simultaneously, there may be an open circuit between terminal EIA1 and ground.
• Read freeze frame data using the Techstream. Freeze frame data records the engine conditions when malfunctions are detected. 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.
