INSPECTION CHART FOR DIAGNOSIS CODE


warning When touching the throttle valve, surely shut off the driving circuits of the throttle valve. In the event that the throttle valve is operated, a finger might be injured as the result of being caught by the throttle valve.
caution When the ignition switch is turned ON with the connector disconnected in proceeding with troubleshooting, the diagnosis code may be stored in other systems. Erase codes if diagnosis codes of all the systems are checked and the codes are output after completion of the troubleshooting.
Code No.

note
  • Do not replace the engine-A/T-ECU until a through terminal check reveals there are no short/open circuit.
  • Check that the engine-A/T-ECU earth circuit is normal before checking for the cause of the problem.
note *1: Carry out the troubleshooting of the installation instructions packaged together with the remote control engine starter.
note *2: When the diagnosis codes relating to the CAN communication error are output, make sure of the vehicle equipment. When the vehicle is not equipped with the system the engine-A/T-ECU communicates to, the diagnosis code is always output. This is not abnormal.
