When DTC is output, be sure to confirm and record.
DTCs may have been stored due to problems unrelated to the steering lock function. Be sure to confirm and record any DTCs output for other systems.
When using the GTS with the engine switch off, connect the GTS to the DLC3 and turn a courtesy light switch on and off at intervals of 1.5 seconds or less until communication between the GTS and the vehicle begins. Then select Model Code "KEY REGIST" under manual mode and enter the following menus: Body Electrical / Entry&Start(CAN). While using the GTS, periodically turn a courtesy light switch on and off at intervals of 1.5 seconds or less to maintain communication between the GTS and the vehicle.
The steering lock ECU (steering lock actuator or upper bracket assembly) does not store history DTCs. If any DTCs are output, confirm and record them as soon as possible. Do not turn the engine switch off or clear the DTCs until the DTCs are confirmed and recorded.
