Diagnostic Aids

An intermittent condition is likely to be caused by a short between circuits 347 and 348, 1403 or 1404 or a malfunctioning shorting bar on driver-side inflator module connector or SIR coil assembly which would require replacement of component.

NOTE: Step numbers refer to step numbers on diagnostic chart. For circuit number identification, see WIRING DIAGRAM .

1) DTC 16 and 22 will set simultaneously when DRIVER SIDE HI circuit is shorted to PASSENGER SIDE HI circuit due to parallel current paths.
3) This test checks if malfunction is in driver-side inflator module circuitry or in SDM wiring harness circuitry.
4) This test checks for short from DRIVER SIDE HI circuits to DRIVER SIDE LO circuit.
5) This test checks if malfunction is in driver-side inflator module or SIR coil.
6) This test checks for short from DRIVER SIDE HI to PASSENGER SIDE LO.
