CHECKING STORED OR INTERMITTENT CODES

With the Scan Tool, record and erase all DTC’s from all Airbag modules.

If equipped with Passenger Airbag On - Off switch, read the DTC’s in all switch positions.

If any ACTIVE codes are present they must be resolved before diagnosing any stored codes.

WARNING: TO AVOID PERSONAL INJURY OR DEATH, TURN THE IGNITION OFF, DISCONNECT THE BAT-
TERY 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 broken, bent, pushed out, spread, corroded, or
contaminated terminals.

The following additional checks may assist you in identifying a possible intermittent problem.

Reconnect any disconnected components and harness connector.
