Be sure to correctly follow the removal and installation procedures for the SRS parts.

NOTICE:: If there is any damage or deformation of airbag installation components or the areas they are installed to, do not attempt to repair them. Replace the damaged components with new ones.

CHECK SRS WARNING LIGHT

Primary check

Turn the ignition switch to ON and check that the SRS warning light turns on.

ii.

Turn the ignition switch off. Wait for at least 2 seconds, and then turn the ignition switch to ON. The SRS warning light comes on for approximately 6 seconds and diagnosis of the airbag system (including the seat belt pretensioners) is performed.

NOTICE:: Turn the ignition switch off when the battery is connected.

HINT:: ·

If the warning light remains on for approximately 6 seconds or more after the ignition switch has been turned to ON, there may be a malfunction with the SRS airbag system.

·

If the warning light occasionally turns on approximately 6 seconds or more after the ignition switch has been turned to ON, 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 ignition switch off or 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.

INSPECT AIRBAG COMPONENTS

Inspect the SRS parts in table below.

Component to Inspect	Procedure
