Inspection Procedure

HINT: 

When the power switch is OFF, the main body ECU may occasionally go into a non-active state called sleep mode. Therefore, before proceeding with the inspection, it is necessary to perform the following steps to wake up the ECU:

With the power switch OFF, open the driver door. Then (with the power switch still OFF) open and close any door several times at 1.5 second intervals.

NOTE:

If the steering lock actuator assembly (steering lock ECU) is replaced, with the power switch OFF and the shift lever on P, open and close the driver side door to record the current lock position into the steering lock ECU. If this is not performed, the hybrid control system may not start.
