DIAGNOSIS CODE CHART

caution

During troubleshooting, a diagnosis code associated with other system may be set when the electric motor switch is set to ON with connector(s) disconnected. On the completion of troubleshooting, confirm all systems for diagnosis code(s). If diagnosis code(s) are set, erase them all.
Be careful that when three minutes or more elapse since the electric motor switch is turned to the ON position without starting the electric motor unit, the EPS-ECU may store diagnosis codes U1100, U1102, U1108, and U1109 as the historic trouble.
