Air Bag Systems

DTC 18- PASSENGER INITIATOR CIRCUIT SHORT TO GROUND

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 "Passenger Side Low" 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) This test determines whether the malfunction is occurring in the passenger air bag (inflator) module circuitry.
2) This test checks for a short from "Passenger Side High" to ground.
3) This test checks for a short from "Passenger Side Low" to ground.

DIAGNOSTIC AIDS:
An intermittent condition is likely to be caused by a short to ground in the passenger air bag (inflator) module circuits. Inspect CKTs "Y/R" and "Y" carefully for cutting or chafing.
If the wiring pigtail of the passenger air bag (inflator) module is damaged the component must be replaced.
