Diagnostic Trouble Code Table
CAUTION:
- During troubleshooting, a DTC associated with other system may be set when the ignition switch is turned on with connector(s) disconnected. On completion, check all systems for DTC(s). If DTC(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 DTCs U0100 and U0121 as past trouble.
NOTE:
For electric power steering system the power supply may not shut off immediately after the ignition switch is turned "OFF".
