NOTE:

.

1. *1: If the vehicle condition returns to normal, the diagnosis code will be automatically erased, and the SRS

warning lamp will return to normal.

2. *2: However, if no diagnosis code resets, the SRS warning lamp will be switched off (The diagnosis code

will be retained).

3. *3: Vehicles without side air bag
4. *4: Vehicles with side air bag
5. If the vehicle has a discharged battery, it will store the diagnosis code 41 or 42. When these diagnosis

codes are read, check the battery.

OPERATION

•

When the left and right front impact sensors
detect a collision, the switches inside the sensors
turns ON.

•

SRS-ECU judges how severe a collision is by
detecting signals from the front impact sensors
and the front air bag analog G-sensor. If the
impact is over a predetermined level, the
SRS-ECU outputs an ignition signal. At this time,
if the front air bag safing G-sensor is on, the SRS
air bag will inflate.
