DIAGNOSIS CODE CHART

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 more than three minutes elapse after the ignition switch is turned ON without starting engine, the electric power steering-ECU may set diagnosis codes U0100 as past trouble.

note

For electric power steering system the power supply may not shut off immediately after the ignition switch is turned "OFF".
