Diagnostic Aids

An intermittent condition is likely caused by short between circuit 1404 and circuit 347, 348, or 1404 or a malfunctioning shorting bar on passenger-side inflator module connector which would require replacement of module.

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

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