Toyota Corolla (E120): Inspection procedure
1 Check security indicator light
- Set the system in 30 seconds after filliping the security indicator to check if the alarm is triggered.


2 Check glass breakage sensor ecu (glass breakage sensor)

- Check the continuity and voltage of the glass breakage sensor ecu, as shown in the illustration and table.
Standard:



3 Check wire harness (tvip ecu glass breakage sensor ecu)

- Disconnect the tvip ecu and glass breakage sensor ecu connectors.
- check the continuity and between the connectors on the harness side, as shown in the illustration and table.
Standard:



4 Check wire harness (glass breakage sensor ecu body ground)

- Disconnect the glass breakage sensor ecu connector.
- check the continuity between the terminal of the glass breakage sensor ecu connector and the body ground, as shown in the illustration and table.

1. Inspection throttle body idle speed control valve assy
Notice:
it is impossible to check the resister value and the operation
of isc valve by itself, because the isc valve
has an ic circuit inside it, which transforms the duty
signal from the ecm to the derive signal.
After check ...
