STEERING LOCK SYSTEM - Power Source Circuit


DESCRIPTION

This circuit supplies voltage from the battery to terminal B of the steering lock ECU (steering lock actuator assembly). This circuit is used as power source for the steering lock ECU (steering lock actuator assembly), motor, communication, and peripheral circuits.

INSPECTION PROCEDURE

NOTICE:
If the steering lock ECU (steering lock actuator assembly) is replaced, with the engine switch off and the shift lever in P, open and close the driver door to record the current lock position into the steering lock ECU (steering lock actuator assembly). If this is not performed, the engine may not start.
HINT:
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 steps to wake up the ECU:
With the engine switch off, open the driver door. Then (with the engine switch still off) open and close any door several times at 1.5 second intervals.
