Restraints Control Module (RCM): Installation

WARNING: This page is about a different car, the 2008 Ford RV Cutaway, 2008 Ford Econoline, 2008 Ford E450 Super Duty, and 2008 Ford Cutaway. However, it is still accessible from the selected car via links, so may be relevant.

WARNING: Always tighten the fasteners of the restraints control module (RCM) and impact sensor (if equipped) to the specified torque. Failure to do so may result in incorrect restraint system operation, which increases the risk of personal injury or death in a crash.

NOTE: Inspect the RCM bracket bolts for corrosion before securing the RCM and bracket assembly to the vehicle.

Install the RCM and bracket assembly and tighten the bolts to specification.
- Tighten to 12 Nm (9 lb-ft).
Connect the small RCM electrical connector.
Make sure the large RCM connector position assurance lever is in the full release position before attempting to connect the connector.

NOTE: Putting the large restraints control module (RCM) electrical wiring connector into the RCM on an angle can cause bad electrical connections and damage components.

NOTE: Do not push the connector to where the lever pivots and seats itself. Light pressure is needed to get the connector into position on the restraints control module (RCM) before using the lever to fully seat the connector.

NOTE: A similar RCM and connectors are shown.

Connect the large RCM electrical wiring connector.
- Using the connector position assurance lever, pivot it toward the RCM, drawing the connector into the RCM.
  - Make sure the thumb tab is engaged to the retainer on the RCM and locked in place.

Install the driver seat. For additional information, refer to SEATING article.
When installing a new RCM, carry out the steps necessary to complete programmable module installation (PMI). For additional information, refer to MODULE CONFIGURATION article.
Prove out the SRS as follows:
Turn the ignition switch from ON to OFF. Wait 10 seconds, then turn the ignition switch back to ON and visually monitor the air bag indicator with the air bag modules installed. The air bag indicator will light continuously for approximately 6 seconds and then turn OFF. If an air bag SRS fault is present, the air bag indicator will:

- fail to light.

- remain lit continuously.

- flash at a 5 Hz rate (RCM not configured).

The air bag indicator might not light 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 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 indicator and any SRS fault discovered must be diagnosed and repaired.

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