Air Bag Systems

DTC 25 - DRIVER INITIATOR CIRCUIT SHORT TO IGNITION

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 voltage measured at "Driver Side Low" is above a specified value for specified time.





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

1) This test determines whether the malfunction is occurring in the driver air bag (inflator) module circuitry.
2) This test checks for a short from "Driver Side High" to B+.
3) This test checks for a short from "Driver Side Low" to B+.
4) This test determines whether the malfunction is in the driver air bag (inflator) module or contact coil assembly.

DIAGNOSTIC AIDS:
An intermittent condition is likely to be caused by a short to B+ in the driver air bag (inflator) module circuits. A DTC 25 history would be accompanied by DTC 7~ current. A careful inspection of the circuits and components indicated on DTC 25 charts is essential to ensure that the replacement SDM will not be damaged.
