ECM Terminal Arrangement

ECM terminal arrangement

1. Steering lock actuator ASSY (Steering lock ECM)





(1) Measure the voltage, resistance, and waveform.





CAUTION:
The steering lock actuator ASSY (Steering lock ECM) is incorporated with one motor and two sensors.

NOTE:
^ When performing measurements while the steering lock actuator motor is stopped, measurements can be made without any special operation.
^ When performing measurements while the steering lock actuator motor is running, the following operations are necessary.
- To unlock the steering, bring the electrical key transmitter SUB-ASSY (Electronic key) into the vehicle and turn the ignition to ACC ON or IG ON.
- To lock the steering, open a door while the vehicle is set to IG OFF & ACC OFF, and the shifter is in the P position (A/T transmission).





(2) Oscilloscope waveform.
