Note

Inspect the fuses for circuits related to this system before performing the following procedure.

Tech Tips

Read freeze frame data using the GTS. 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.

      The voltage between ST relay terminal 2 and body ground changes when the connector is disconnected. B

      Tech Tips


      • The voltage before disconnecting the connector refers to the value measured in step 22. Check whether the voltage after disconnecting the connector changes as compared to the voltage value measured in step 22.

      • If the voltage is the same before and after disconnecting the connector, the ECM is normal.
