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
  • During diagnosis, a diagnosis code associated with other system may be set when the ignition switch is turned on with connector(s) disconnected. On completion, confirm all systems for diagnosis code(s). If diagnosis code(s) are set, erase them all.
  • If an incorrect variant code is entered in the ABS/ASC-ECU, ETACS-ECU and Engine-ECU or Engine-A-M/T-ECU, the system may not work normally. Before inspection, confirm that a correct variant code has been entered.(Refer to GROUP 00, Precautions Before Service - How to Perform Variant Coding .)
note When the engine ECU stores the diagnosis code, the learning of the estimated ethanol is not carried out. For this, the difference can possibly arise between the ethanol concentration stored by the engine ECU and the ethanol concentration in the fuel tank. After the troubleshooting, therefore, perform the forced learning of the estimated ethanol concentration. (Refer to GROUP 00 - Precautions Before Service - Forced Learning of Estimated Ethanol Concentration ) <FFV>

note
  • Do not replace the engine-ECU or engine-A-M/T-ECU until a through terminal check reveals there are no short/open circuit.
  • Check that the engine-ECU or engine-A-M/T-ECU earth circuit is normal before checking for the cause of the problem.
