NOTICE:

Connect the correct terminals to avoid a malfunction.

(b) Check for DTCs (History DTCs).

(1) Turn the ignition switch off.

SST: 09843-18040

NOTICE:

Connect the correct terminals to avoid a malfunction.

(3) Turn the ignition switch ON, and wait for at least 60 seconds.

(c) Read the DTCs.

(1) Read the blinking patterns of the DTCs. As an example, the blinking patterns for the normal system code and DTCs 11 and 31 are shown in the illustration.

  • Normal system code indication (without history DTCs)

    The light blinks twice per second.

  • Normal system code indication (with history DTCs)

    When a history DTC is stored in the airbag sensor assembly, the light blinks only once per second.

  • DTC indication

    The first blink(s) indicate the first number of the DTC. The second blink(s) indicate the second number of the DTC and occur after a 1.5-second pause.

NOTICE:

When a DTC includes a letter (such as DTC 8A), the light blinks 8 times and then blinks 10 times to indicate the A after a 1.5-second pause.
