DIAGNOSTIC TROUBLE CODE CHART
caution
  • During diagnosis, a diagnostic trouble 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 diagnostic trouble code(s). If diagnostic trouble 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 diagnostic trouble code U0100 as past trouble.
noteFor electric power steering system the power supply may not shut off immediately after the ignition switch is turned "OFF".
