Disconnect the F15 and F16 power management control ECU connectors.

Measure the voltage and resistance according to the value(s) in the table below.

HINT:

Measure the values on the wire harness side with the connector disconnected.

HINT:

The waveform of the steering lock actuator motor stopped can be checked without performing any particular operation.
The waveform of the steering lock actuator motor operating can be checked if either of the following operations is performed:
- To unlock the steering, bring the electrical key transmitter sub-assembly into the cabin and turn the power switch on (ACC) or on (IG).
- To lock the steering, open a door with the power switch off and the shift lever in P.

Using an oscilloscope, check the waveform of the ECU.

NOTE:

The oscilloscope waveform shown in the illustration is an example for reference only. Noise, chattering, etc. are not shown.
