SRS ConfigurationNLRS0010
SRS585-D
The air bag deploys if the diagnosis sensor unit activates while the ignition switch is in the“ON”or“START”
position.
The collision modes for which supplemental restraint systems are activated are different among the SRS sys-
tems. For example, the driver air bag module and front passenger air bag module are activated in a frontal
collision but not in a side collision.
SRS configurations which are activated for some collision modes are as follows:
SRS configuration Frontal collision Left side collision Right side collision

Maintenance ItemsNLRS0012CAUTION:
Do not use electrical test equipment to check SRS circuit.
1. Check operation of“AIR BAG”warning lamp.
After turning ignition key to“ON”position,“AIR BAG”warning
lamp illuminates. The“AIR BAG”warning lamp will go off after
about 7 seconds if no malfunction is detected. If any of the fol-
lowing“AIR BAG”warning lamp conditions occur, immediately
check the air bag system. Refer to RS-45 for details.
+The“AIR BAG”warning lamp does not illuminate when the
ignition switch is turned“ON”.
+The“AIR BAG”warning lamp does not go off about 7 seconds
after the ignition switch is turned“ON”.
+The“AIR BAG”warning lamp blinks after about 7 seconds after
the ignition switch is turned“ON”.
2. Visually check SRS components.
1) Diagnosis sensor unit
+Check diagnosis sensor unit and bracket for dents, cracks and
