Note
The steering lock actuator assembly (steering lock ECU) does not store past 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.
DTCs may have been stored due to problems unrelated to the steering lock actuator assembly (steering lock ECU) system. Be sure to confirm and record any DTCs output for other systems.
When using the intelligent tester with the engine switch off, perform either of the following: 1) Turn a courtesy light switch on and off at intervals of 1.5 seconds or less until communication between the intelligent tester and vehicle begins, or 2) connect the intelligent tester to the vehicle and select "MANUAL" from the initial screen on the intelligent tester, and then select "KEY REGIST" under Model Code.
