WARNING: This page is about a different car, the 2018 Ford F-550 Super Duty, 2018 Ford F-450 Super Duty, 2018 Ford F-350 Super Duty, and 2018 Ford F-250 Super Duty. 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 component.

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 component.

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 as follows: Turn the ignition from ON to OFF. Wait 10 seconds, then turn the ignition back to ON and monitor the air bag warning indicator with the air bag modules installed. The air bag warning indicator illuminates continuously for approximately 6 seconds and then turns off. If a SRS fault is present, the air bag warning indicator either fails to light, remains lit continuously or flashes.
- The flashing might not occur until approximately 30 seconds after the ignition has been turned from OFF to ON. 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 sounds in a pattern of 5 sets of 5 beeps. If this occurs, diagnose and repair the air bag warning indicator and any SRS faults.
