Toyota Corolla (E120): Inspection procedure
1 Check connector
- Disconnect the negative (–) terminal cable from the battery, and wait at least for 90 seconds.
- check the connection of the combination meter connector and the
airbag sensor assy center connectors.
Ok: the connectors are connected.


2 Check combination meter assy

- Disconnect the connector from the combination meter.
- connect the negative (–) terminal cable to the battery, and wait at least for 2 seconds.

- Turn the ignition switch to on, and wait at least for 6 seconds.
- measure the voltage between sw and body ground.
Ok: voltage: above 8 v


3 Check instrument panel wire(airbag sensor assy center–combination meter assy)

- Turn the ignition switch to lock.
- disconnect the negative (–) terminal cable from the battery, and wait at least for 90 seconds.
- disconnect the connector from the airbag sensor assy center.
- measure the resistance between la and body ground.
Ok: resistance: 1mΩ or higher


Replace air bag sensor assy center
4 Check instrument panel wire(airbag sensor assy center–combination meter assy)

- For the connector (on the airbag sensor assy center side)
between the combination meter and the airbag sensor
assy center, measure the resistance between sw and

Inspection procedure
Hint:
hand–held tester only:
narrowing down the trouble area is possible by performing ”a/f control” active
test (heated oxygen
sensor or other trouble areas can be distinguished). Perform active test using

Inspection procedure
Hand–held tester:
1 Check operation of stop light
Check if the stop lights go on and off normally when the brake pedal is
depressed and released.
2 Inspect stop light switch assy
Check the resistance between the terminals when the
switch is turned on and off.
