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.
Standard:

Circuit description
When a misfire occurs in the engine, hydrocarbons (hc) enter the exhaust in
high concentrations. If this hc
concentration is high enough, there could be an increase in exhaust emissions
levels. High concentrations
of hc passing through the catalyst also cause to temperature of the catalyst to ...
