|DTC Code||DTC Name|
|B2781||Open / Short in Steering Lock ECU|
The steering lock ECU and steering lock actuator assembly are supplied as a unit.
The steering lock ECU detects the steering lock position through the signals from the lock and unlock position sensors.
The steering lock ECU activates the steering lock motor based on permission signals from the power management control ECU and the certification ECU.
The diagnosis information of the steering lock ECU is transmitted to the intelligent tester via the certification ECU as the steering lock ECU is not connected to the CAN communication system.

Either condition is met:
CAUTION / NOTICE / 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.
If the steering lock actuator assembly (steering lock ECU) is replaced, with the engine switch off and the shift lever in P (except Manual Transaxle), open and close the driver side door to record the current lock position into the steering lock ECU. If this is not performed, the engine may not start.
When replacing the steering lock ECU, registration must be performed. Refer to the Service Bulletin for the registration procedure.
