Control Module

The first technical step for repairing an Air Bag Control Module requires checking that back up power supply drains completely to minimize both accidental air bag activation risks and personal injuries. First remove the ground connection from the battery while waiting for at least one minute. Additionally disconnect all auxiliary batteries together with power supplies if the vehicle has them. The orientation of the Restraints Control Module (RCM) serves as a crucial condition for system functionality hence inspect the mounting and bracket for damage when the vehicle was in a crash that hit the right cowl A-pillar area and install a new RCM if damage is detected regardless of air bag deployment status. Attempt to handle electronic digital modules with care since static electrical discharge creates harm. First detach the ground cable of the battery and take off the right-hand side sill plate and push the carpet to one side. Unplug the locking clips from the RCM electrical connector before disconnecting its wires while removing three mounting bolts to extract the RCM. Reinstall the RCM by following the removal steps backwards and make sure to correct the torque setting of retaining bolts to achieve operational system functionality. Check air bag system functionality as a last step after installation. Use the Restraint System Diagnostic Tool only for service work because operating it without removing it first from the vehicle creates safety risks that violate vehicle safety standards.

A new Restraint Control Module (RCM) requires programming using the correct vehicle specifications during installation. First verify that all SRS components are properly installed together with an attached battery. The Data Link Connector (DLC) should receive a scan tool while you turn the key to the RUN position. The scan tool demands following its programming instructions to apply the side air bag configuration on the RCM equipment according to specifications where "air bag Configuration 16" corresponds to Town Cars with side air bags and "air bag Configuration 17" matches Town Cars without side air bags exclusively used for limousines and hearses. Turn the key to OFF mode after configuration procedures and proceed with system proofing. The proven results of Lamp Fault Codes (LCFs) require consulting the Diagnostic Trouble Code (DTC) Priority Table to continue diagnostics.
