Toyota Corolla (E120): Inspection procedure
1 Inspect fuse(stop)
- Turn the ignition switch to off.
- remove the stop fuse from the instrument panel j/b.
- check continuity of the stop fuse.
Ok: continuity
2 Inspect stop lamp switch assy
- Disconnect the stop lamp switch assy connector.
- check continuity between each terminal of stop lamp
switch assy.
Ok:
3 Inspect cruise control actuator assy
- Turn the ignition switch to off.
- disconnect the cruise control actuator assy connector.
- measure resistance between terminals 3 (l) and 4 (gnd)
of the cruise control actuator assy.
Ok: resistance: 34.65 – 42.35 Ω
4 Check harness and connector(between cruise control actuator assy and body ground)
- Check continuity between the terminal 4 (gnd) of the
cruise control actuator assy and body ground.
Ok: continuity
5 Check harness and connector(between cruise control ecu assy and cruise control actuator assy)
- Check for open and short circuit in harness and connector between cruise control ecu assy and cruise control actuator assy (actuator magnetic clutch)
Check and replace cruise control ecu assy

Circuit description
A flat type knock sensor (non–resonant type) has the structure that can
detect the vibration in a wider band
of frequency from about 6 khz to 15 khz and has the following features.
Knock sensors are fitted on the cylinder block to detect the engine knocking.
The sensor contains a piezoele ...
