(1) Turn the power switch on (IG) and check that the SRS warning light comes on.

NOTICE:
Turn the power switch off when the auxiliary battery is connected.
HINT:
- If the warning light remains on for approximately 6 seconds or more after the power switch has been turned on (IG), there may be a malfunction with the SRS airbag system.
- If the warning light occasionally turns on approximately 6 seconds or more after the power switch has been turned on (IG), there may be a short to +B, short to ground or an open in the SRS warning light circuit.
- If the warning light illuminates after turning the power switch off or on (ACC), there may be a malfunction in the power source circuit or combination meter assembly.
- The SRS warning light turns off, and then turns on. This blinking pattern indicates a source voltage drop. The SRS warning light turns off 10 seconds after the source voltage returns to normal.
