  17. Connect the driver air bag module.
    1. Connect the horn electrical connector.
      2. NOTE: The clockspring electrical connectors are unique and cannot be reversed when connected to the driver air bag module. Match the electrical connector key to the keyway in the driver air bag module. Do not force the electrical connectors into the driver air bag module. Damage to the connector or component may occur.
    2. Connect the driver air bag module electrical connectors as noted during removal.
    3. Install the driver air bag module electrical wiring into the driver air bag wiring clip.

    NOTE: With the driver air bag module held as close to the steering wheel as possible, take up the slack in the wiring by gently tucking any excess length into the pocket at the bottom of the steering wheel before rocking the driver air bag module into place.
  18. Align the 4 driver air bag module locking pins to the openings in the steering wheel and position the driver air bag module in place.

    WARNING: Remove restraint system diagnostic tools from the vehicle prior to road testing. If tools are not removed, the supplemental restraint system (SRS) device may not deploy in a crash. Failure to follow this instruction may result in serious personal injury or death in a crash and possibly violate vehicle safety standards.
  20. Make sure all Restraint System Diagnostic Tool(s) that may have been installed during the repair have been removed from the vehicle and all SRS components are connected.
  21. Turn the ignition switch from OFF to ON.
  22. Install the RCM fuse 22 (10A) to the CJB and install the cover.
    23. WARNING: Make sure no one is in the vehicle and there is nothing blocking or placed in front of any air bag module when the battery is connected. Failure to follow these instructions may result in serious personal injury in the event of an accidental deployment.
  23. Connect the battery ground cable. For additional information, refer to BATTERY, MOUNTING & CABLES article.
  24. Prove out the SRS as follows:

    Turn the ignition key from ON to OFF. Wait 10 seconds, then turn the key back to ON and visually monitor the air bag warning indicator with the air bag modules installed. The air bag warning indicator will light continuously for approximately 6 seconds and then turn off. If an air bag SRS fault is present, the air bag warning indicator will:

    - fail to light.

    - remain lit continuously.

    - flash.

    The flashing might not occur until approximately 30 seconds after the ignition switch has been turned from the OFF to the ON position. This is the time required for the RCM to complete the testing of the SRS. If the air bag warning indicator is inoperative and a SRS fault exists, a chime will sound in a pattern of 5 sets of 5 beeps. If this occurs, the air bag warning indicator and any SRS fault discovered must be diagnosed and repaired.

    Clear all continuous DTCs from the RCM using a scan tool.
