Air Bag Systems

DTC 22 - DRIVER INITIATOR CIRCUIT RESISTANCE LOW

CAUTION:
- When measurements are requested in this chart use specified digital multimeter with correct terminal adapter from special tool (Connector test adapter kit).
- When a check for proper connection is requested refer to "INTERMITTENTS AND POOR CONNECTIONS" in this section.
- When an open in air bag wire harness, damaged wire harness, connector or terminal is found, replace wire harness, connectors and terminals as an assembly.

DTC WILL SET WHEN:
The combined resistance of the driver air bag (inflator) module, contact coil assembly, harness wiring and connector terminal contact is below a specified value for specified time.





DTC CHART TEST DESCRIPTION:
Number(s) below refer to circled number(s) on the diagnostic chart.

1) DTC 16 and 22 will set simultaneously when the "Driver Side High" circuit is shorted to the "Passenger Side High" circuit due to parallel current paths.
2) This test determines whether the malfunction is in the driver air bag (inflator) module circuitry or in the SDM wiring harness circuitry.
3) This test checks for a short from the "Driver Side High" circuit to the "Driver Side Low" circuit.
4) This test checks for a short from the "Driver Side High" circuit to the "Passenger Side Low" circuit.
5) This test determines whether the malfunction is in the driver air bag (inflator) module or the contact coil assembly.

DIAGNOSTIC AIDS:
An intermittent condition is likely to be caused by a short between CKT "G/R" and CKT "G", CKT "Y/R" or CKT "Y", or a malfunctioning shorting bar on the driver air bag (inflator) module or contact coil assembly which would require replacement of the component. The test for this diagnostic trouble code is only run while the "AIR BAG" warning lamp is performing the bulb check, unless DTC 17 or DTC 26 is detected. When a scan tool "Clear Codes" command is issued and the malfunction is still present, the DTC will not reappear until the next ignition cycle.
