Toyota Corolla (E120): Inspection procedure
1 Check operation(overdrive)
- Drive the vehicle after the engine warms up.
- check that overdrive on e off occurs by an operation of the o/d switch on–off.
2 Inspect terminal voltage(od)
- Remove the cruise control ecu assy with the connector still connected.
- turn the ignition switch to on.
- disconnect the cruise control ecu assy connector.
- measure voltage between terminal 14 (od) of harness
side connector of cruise control ecu assy and body
ground.
Ok: voltage: 10 – 14 v
3 Inspect terminal voltage(ect)
- Connect the cruise control ecu assy connector.
- perform the test drive after engine warms up.
- check voltage between terminal 6 (ect) of cruise control
ecu assy connector and body ground when o/d switch
is on and off.
Ok:
4 Check harness and connector(between cruise control ecu assy and electronically controlled transmission solenoid)
- Check for open and short circuit in harness and connector between cruise control ecu assy and electronically controlled transmission solenoid
Check and replace cruise control ecu assy
5 Check harness and connector(between cruise control ecu assy and ecm)
- Check for open and short circuit in harness and connector between cruise control ecu assy and ecm
Check and replace cruise control ecu assy
