B2781 - Open / Short in Steering Lock ECU
DESCRIPTION
If the steering lock ECU (steering lock actuator assembly) determines that there is a malfunction inside the ECU, it outputs this DTC. Diagnostic
communication between the steering lock ECU (steering lock actuator assembly) and the Techstream is performed via the certification ECU (smart
key ECU assembly) as the steering lock ECU (steering lock actuator assembly) is not connected to CAN.
The steering lock ECU and steering lock actuator assembly are supplied as a unit. The steering lock ECU (steering lock actuator assembly) detects
the steering lock position through the signals from the lock and unlock position sensors.
The steering lock ECU (steering lock actuator assembly) activates the steering lock motor based on permission signals from the power management
control ECU and the certification ECU (smart key ECU assembly).
INSPECTION PROCEDURE
NOTICE:
* If the steering lock ECU (steering lock actuator assembly) is replaced, with the engine switch off and the shift lever to P, open
and close the driver side 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.
* After replacing the steering lock ECU (steering lock actuator assembly), perform the key ID code registration See:
