TEST FOR INTERMITTENT CONDITION
With the scan tool, record and erase all DTCs from all Airbag modules.
If any ACTIVE codes are present they must be resolved before diag-
nosing any stored codes.
WARNING: To avoid personal injury or death, turn the ignition off,
disconnect the battery and wait two minutes before proceeding.
Using the wiring diagram/schematic as a guide, inspect the wiring and
connectors.
Look for chaffed, pierced, pinched, or partially broken wires and bro-
ken, bent, pushed out, spread, corroded, or contaminated terminals.
The following additional checks may assist you in identifying a possi-
ble intermittent problem.
Reconnect any disconnected components and harness connector.
WARNING: To avoid personal injury or death, turn the ignition on,
then reconnect the battery.
With the scan tool, monitor active codes as you work through the fol-
lowing steps.
WARNING: To avoid personal injury or death, maintain a safe distance from all airbags while performing the
following steps.
Wiggle the wiring harness and connectors of the related airbag circuit or component.
If codes are related to the Driver Airbag circuits, rotate the steering wheel from stop to stop.
If only stored codes return, continue the test until the problem area has been isolated.
In the previous steps you have attempted to recreate the conditions responsible for setting the active DTC in ques-
tion.
Does the scan tool display any ACTIVE DTCs?
Yes
