Function of the SRS Warning Light
Function of the SRS warning light1. Primary check.
Turn the ignition switch to the LOCK position. Wait at least 2 seconds, then turn the ignition switch to the ON position. The SRS warning light comes on for approximately 6 seconds and the diagnosis of the SRS airbag system (including the seat belt) is performed.
HINT: If trouble is detected during the primary check, the SRS warning light remains on or blinks even after the primary check period (for approximately 6 seconds) has elapsed.
2. Constant check.
After the primary check, the airbag sensor assembly center activates the SRS airbag system and monitors it for trouble constantly.
HINT: If trouble is detected during the constant check, the airbag sensor assembly center functions as follows:
- The SRS warning light comes on or blinks.
- The SRS warning light comes on, and then goes off. This blinking pattern indicates the source voltage drop.
- The SRS warning light goes off 10 seconds after the source voltage returns to normal.
3. Review.
1. When the airbag system is normal;
The SRS warning light comes on only during the primary check period (for approximately 6 seconds after the ignition switch is turned to the ON position).
2. When the airbag system has trouble;
- The SRS warning light remains on or blinks even after the primary check period has elapsed.
- The SRS warning light goes off after the primary check, but comes on or blinks again during the constant check.
- The SRS warning light does not come on when turning the ignition switch from the LOCK to ON position.
HINT: The airbag sensor assembly center keeps the SRS warning light ON if the airbag has been deployed.
