Toyota Corolla (E120): Inspection procedure
1 Check operation(starter)
- Check that the starter operates normally and that the engine starts.


2 Input signal check

- See input signal check on page 05–745.
- check the indicator light when shifting into except d position.
Ok: the indicator light goes off when shifting into except d position.


3 Inspect terminal voltage(d)

- Turn the ignition switch to on.
- measure voltage between terminal 4 (d) of cruise control
ecu assy connector and body ground when shifting into
d position and other positions.
Ok:



4 Check harness and connector(between cruise control ecu assy and park/neutral position switch)
- Check for open and short circuit in harness and connector between cruise control ecu assy and park/ neutral position switch


Check and replace cruise control ecu assy
