3.

CHECK POWER SUPPLY AND GROUND CIRCUIT

Check the power supply and the ground circuit of the air bag diagnosis sensor unit. Refer to 

SRC-189, "Wiring

Diagram — SRS AIR BAG CONTROL SYSTEM —"

.

Is the inspection result normal?

YES (Present error)>>Replace the air bag diagnosis sensor unit. Refer to 

SRC-8, "Component Parts Loca-

tion"

.

YES (Past error)>>Error was detected in the air bag diagnosis sensor unit branch line.
NO

>> Repair the power supply and the ground circuit.
