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

Circuit description
When the ignition switch is turned on, battery positive voltage is applied to
the coilwhich closes the contacts
of the efi main relay (marked: efi) and supplies power to terminal +b of the ecm.
This signal causes current to flow to the coil, closing the contacts of the efi
relay and supplyin ...

Monitor description
The ecm continuously monitors its internal circuits. This self–check insures
that the ecm is functioning properly.
If a malfunction is detected, the ecm will set the appropriate dtc and
illuminate the mil.
