Inspection Procedure

WARNING: This page is about a different variant/trim than selected.

When the engine 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 step to wake up the ECU:

Before starting the inspection, with the engine switch off, open the driver's door. Then (with the engine switch still off) open and close any door several times in 1.5-second intervals.

NOTE:

If the steering lock actuator assembly (steering lock ECU) is replaced, with the engine switch off and the shift lever in the N position, open and close the driver's door to record the current lock position into the steering lock ECU. If this is not performed, the engine may not start.
