Air Bag Systems

CAUTION:
- When measurements are requested in this table 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 INTERMITTENT 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 above a specified value for specified time.

DTC 21 (Steps 1 - 4):

DTC TABLE DESCRIPTION:
Number(s) below refer to circled number(s) on the diagnostic table.
1. This test determines whether the malfunction is in the driver air bag (inflator) module circuitry or in the SDM wiring harness circuitry.
2. This test checks whether the malfunction is due to high resistance in CKT "G".
3. This test checks whether the malfunction is due to high resistance in CKT "G/R".
4. This test determines whether the malfunction is in the driver air bag (inflator) module or the contact coil assembly.
