Toyota Corolla (E120): Inspection procedure
1 Check d squib circuit(airbag sensor assy center – horn button assy)

- Disconnect the negative (–) terminal cable from the battery, and wait at least for 90 seconds.
- disconnect the connector between the airbag sensor assy center and the horn button assy.
- for the black connector (on the spiral cable sub–assy
side) between the horn button assy and the spiral cable
sub–assy, measure the resistance between d2+ and
body ground.
Ok: resistance: 1 mw or higher


2 Check air bag sensor assy center
Sst 09843–18040

- Connect the connector to the airbag sensor assy center.
- using a service wire, connect d2+ and d2– of the black connector (on the spiral cable sub–assy side) between the horn button assy and the spiral cable sub–assy.
- connect the negative (–) terminal cable to the battery, and wait at least for 2 seconds.
- turn the ignition switch to on, and wait t least for 20 seconds.
- clear the dtc stored in memory .
- turn the ignition switch to lock, and wait at least for 20 seconds.
- turn the ignition switch to on, and wait at least for 20 seconds.
- check the dtc .
Ok: dtc b1182/19 is not output.
Hint
: codes other than code b1182/19 may be output at this time, but they are not relevant to this check.


3 Check d squib
Sst 09843–18040

- Turn the ignition switch to lock.
- disconnect the negative (–) terminal cable from the battery, and wait at least for 90 seconds.
- connect the horn button assy connectors.
- 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 20 seconds.
- clear the dtc stored in memory .
- turn the ignition switch to lock, and wait at least for 20 seconds.
- turn the ignition switch to on, and wait at least for 20 seconds.
- check the dtc .
Ok: dtc b1182/19 is not output.
Hint
: codes other than code b1182/19 may be output at this time, but they are not relevant to this check.


4 Use simulation method to check


Replace all srs components including the wire harness
5 Check instrument panel wire(airbag sensor assy center – spiral cable sub–assy)

- Disconnect the connector of the instrument panel wire.
- for the connector (on the spiral cable sub–assy side) between
the airbag sensor assy center and the spiral cable
sub–assy, measure the resistance between d2+ and
body ground.
Ok: resistance: 1 mΩ or higher


6 Check spiral cable sub–assy

- For the black connector (on the spiral cable sub–assy
side) between the horn button assy and the spiral cable
sub–assy, measure the resistance between d2+ and
body ground.
Ok: resistance: 1 mΩ or higher


7 Use simulation method to check


Replace all srs components including the wire harness
Other materials:
Adjustment
1. Check and adjust brake pedal height
Inspect brake pedal height.
Pedal height from asphalt sheet:
m/t: 134.9 – 144.9 Mm (5.311 – 5.703 In.)
A/t: 136.0 – 146.0 Mm (5.353 – 5.747 In.)
Disconnect the connector from the stop lamp
switch.
Remove the stop lamp ...
Inspection procedure
