Restraints Control Module (RCM): Installation

WARNING: This page is about a different car, the 2018 Lincoln Navigator. However, it is still accessible from the selected car via links, so may be relevant.

WARNING: Incorrect repair techniques or actions can cause an accidental Supplemental Restraint System deployment. Make sure the restraint system is depowered before reconnecting the component. Refer to Supplemental Restraint System (SRS) Depowering . Failure to precisely follow depowering instructions could result in serious personal injury from an accidental deployment.

To install, reverse the removal procedure.
Repower the SRS. For a new RCM, do not prove out the SRS at this time. Refer to: Supplemental Restraint System (SRS) Repowering .
NOTE: This step is only necessary when installing a new RCM.

Using a diagnostic scan tool, complete the PMI process for the RCM following the on-screen instructions.
NOTE: This step is only necessary when installing a new RCM.

Using a diagnostic scan tool, carry out the ABS module initialization following the on-screen instruction.
If a new RCM was installed, prove out the SRS. Verify all airbags are installed and connected and the ignition is OFF. Wait 10 seconds, then turn the ignition ON and monitor the airbag warning indicator. The airbag warning indicator illuminates continuously for approximately 6 seconds and then turns off. Continue to monitor the airbag warning indicator for approximately 30 seconds, as this is the time required for the RCM to complete testing of the SRS.
- *If a SRS fault is present, the airbag warning indicator either fails to light, remains lit continuously or flashes. The flashing may not occur until approximately 30 seconds after the ignition has been turned from OFF to ON. If this occurs, diagnose and repair any SRS faults before proceeding with other repairs.
- *If, after the ignition has been turned on for 30 seconds, the airbag warning indicator remains unlit with no chime or SRS message displayed in the message center, no SRS fault is present.
- *If the airbag warning indicator is inoperative and a SRS fault exists, a chime sounds in a pattern of 5 sets of 5 beeps or a message displays in the message center. If this occurs, diagnose and repair the airbag warning indicator and any SRS faults before proceeding with other repairs.
