Examples, the blinking patterns for the normal system indication, the past DTC indication, and the present DTC indication are shown in the illustration.
- Normal system indication The SRS warning light blinks twice per second.
- Past DTC indication When any past DTCs are stored in the center airbag sensor assembly, the SRS warning light blinks only once per second.
- Present DTC indication The first blinking indicates the first digit of a 2-digit DTC. The second blinking occurs after a 1.5-second pause to indicate the second digit.
If there are more than one DTC, there is a 2.5-second pause after each one. After all the DTC are displayed, there is a 4.0-second pause, and they are repeated.
HINT:
- If 2 or more malfunctions are found, the indication begins with the smaller numbered code.
- If DTCs are indicated without connecting the terminals, proceed to the "TC and CG Terminal Circuit".
