Toyota Corolla (E120): Inspection procedure
1 Check p squib circuit(airbag sensor assy center – instrument panel passenger airbag 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 instrument panel passenger airbag assy.
- connect the negative (–) terminal cable to the battery, and wait at least for 2 seconds.
- turn the ignition switch to on.
- for the connector (on the instrument panel passenger airbag assy side) between the airbag sensor assy center and the instrument panel passenger airbag assy, measure the voltage between p2+ and body ground.
Ok: voltage: below 1 v
2 Check air bag sensor assy center
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 connector to the airbag sensor assy center.
- using a service wire, connect p2+ and p2– of the connector (on the instrument panel passenger airbag assy side) between the airbag sensor assy center and the instrument panel passenger airbag assy.
- 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 b1188/56 is not output.
Hint
: codes other than code b1188/56 may be output at this time, but they are not relevant to this check.

Cruise control
The vehicle can be driven at
a set speed even if the
accelerator pedal is not
depressed.
Use the cruise control only
on highways and expressways.
WARNING
■For safe use
Driving safely is solely the
responsibility of the driver.
Therefore, do not overly rely on
this system. The driver is solel ...

Hint:
if different dtcs related to different systems that have terminal e2
as the ground terminal are output
simultaneously, terminal e2 may be open.
