  2. CHECK SRS WARNING LIGHT


    1. Primary check


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

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

        Note

        Turn the power switch off when the auxiliary battery is connected.

        Tech Tips


        • 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.

  3. FUNCTION OF PASSENGER AIRBAG ON/OFF INDICATOR (w/ Airbag Cutoff Switch)
