B2781
Open / Short in Steering Lock ECU
One of the following conditions is met (1-trip detection logic (Only output while a malfunction is present and the engine switch is on (IG).)):
·
The steering lock sensor or unlock sensor is malfunctioning (When both detection switches turn on, the system is determined to be malfunctioning.).
·
The steering lock motor activation circuit has a short circuit.
·
The steering lock motor activation circuit has an open circuit.
DTC Output Confirmation Operation: No confirmation operation is necessary (monitoring is continuous).
B2782
Power Source Control ECU Malfunction
Either of the following conditions is met (1-trip detection logic (Only output while a malfunction is present and the engine switch is on (IG).)):
·
The steering lock motor activation command circuit has a short circuit.
·
The steering lock motor activation command circuit has an open circuit.
HINT:
If the power supply signal from the LIN communication line does not match the power supply signal from the direct line, the system is determined to be malfunctioning.
DTC Output Confirmation Operation: Perform a steering lock/unlock operation. (The steering locks when a door is opened with the shift lever in P (for CVT) and the engine switch off. The steering unlocks when the engine switch is turned on (ACC) or on (IG) while carrying the key.)
B2788
IG2 Signal Malfunction
Mismatch between the steering lock ECU (steering lock actuator assembly) IG2 input from the LIN communication system and from the direct line (1-trip detection logic (Only output while a malfunction is present and the engine switch is on (IG).)).
DTC Output Confirmation Operation: No confirmation operation is necessary (monitoring is continuous).
