Diagnostic Test

RECORD AND ERASE ALL RESTRAINT SYSTEM DTC
1. With the scan tool, record and erase all Diagnostic Trouble Code (DTC) from all restraints system modules. Monitor for any active codes as you work through the following steps.
  - Review the code monitor and set conditions for any DTC that are stored and attempt to reproduce the conditions listed
  - Wiggle the wiring harness and connectors of the related airbag circuit, sensor or component
  - If codes are related to the Driver Airbag circuits, rotate the steering wheel from stop to stop
  - Turn the ignition off. Refer to any Technical Service Bulletins (TSB) that may apply
  - Note: If equipped with an airbag on/off switch, perform the steps above in all switch positions.
  Was the source of the customer complaint found or did any DTC appear and stay active?

ATTEMPT TO REPRODUCE THE CONDITION
1. In the event the customer complaint cannot be duplicated due to an intermittent condition in the restraints system, the following may aid in attempting to reproduce the condition.
  WARNING:
  Turn the ignition off, disconnect the battery and wait two minutes before proceeding. Failure to follow these instructions may result in possible serious or fatal injury.
  
  CAUTION:
  Disconnecting or connecting the OCM connectors with the battery connected permanently damages the OCM.
  - Using the wiring diagram/schematic as a guide, inspect the wiring and connectors related to the stored code or component in question.
  - Look for chafed, pierced, pinched or partially broken wires and broken, bent, pushed out, spread, corroded or contaminated terminals.
  - Reconnect any disconnected components and harness connectors and make sure they are properly seated.
  - Note: If equipped with an airbag on/off switch, perform the steps above in all switch positions.
  - If numerous trouble codes were set, use a schematic and inspect any common ground or supply circuits.
  Was the source of the intermittent condition located?
