INSPECTION CHART FOR DIAGNOSIS CODE


warning
  • If the intake air control flap is operated, a finger might be injured as the result of being caught by the intake air control flap. When touching the intake air control flap, surely shut off the driving circuits of the intake air control flap.
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.
note
  • Do not replace the engine-ECU until a through terminal check reveals there are no short/open circuit.
  • Check that the engine-ECU earth circuit is normal before checking for the cause of the problem.
