Hint:
The standard normal voltage between each pair of ecm terminals is shown in the table below. The appropriate conditions for checking each pair of terminals are also indicated. The result of checks should be compared with the standard normal voltage for that pair of terminals, displayed in the specified condition column. The illustration above can be used as a reference to identify the ecm terminal locations.
Hint:
*: The ecm terminal voltage is constant regardless of the output voltage from the sensor.

Hint:
The waveform varies depending on the can communication signal.
Can
communication signal
Hint:
The waveform varies depending on the can communication signal.
Generator
Hint:
A constant value is not output, as the duty ratio varies depending on the electrical load and battery condition.

Hint:
A constant value is not output, as the duty ratio varies depending on the electrical load and battery condition.
Steering wheel
Adjustment procedure
1. Hold the steering wheel and
push the lever down.
2. Adjust to the ideal position by
moving the steering wheel
horizontally and vertically.
After adjustment, pull the lever up
to secure the steering wheel.
