9A1-18 RESTRAINT CONTROL SYSTEM

DTC Will Clear When
The ignition switch is turned “OFF.”

DTC Chart Test Description
Number(s) below refer to step number(s) on the
diagnostic chart:
2.
This test determines whether the malfunction is in
the SRS control unit.
3.
This test verifies connection of the yellow connector.
4.
This test cheeks for proper operation of the shorting
clip in the yellow connector.
5.
The test checks for a malfunction passenger air bag
assembly.
6.
This test determines whether the malfunctioning is
due to shortening in the wiring.
Diagnostic Aids
An intermittent condition is likely to be caused by a short
between circuits “Passenger Bag High” and “Passenger
Bag Low” or a malfunctioning shorting clip on the
passenger air bag assembly which would require
replacement of the air bag assembly. The test for this
diagnostic trouble code is only run while “AIR BAG”
warning lamp is performing the bulb check. 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.

RESTRAINT CONTROL 9A1-21

DTC Will Clear When
The ignition switch is turned “OFF.”

DTC Chart Test Description
Number(s) below refer to step number(s) on the
diagnostic chart:
2.
This test determines whether the malfunction is in
the SRS control unit.
3.
This test verifies proper connection of the yellow
connector.
4.
This test checks for proper contact and/or corrosion
of the yellow connector terminals.
5.
The test checks for a malfunctioning passenger ai
r
bag assembly.

This malfunction is no longer occurring and the ignition
switch is turned “OFF”.

DTC Chart Test Description
Number(s) below refer to circled number(s) on the
diagnostic chart.
2.
This test determines whether the SRS control unit is
malfunctioning.
