Diagnostic Module

The Restraints Control Module (RCM) requires servicing under two conditions: first check that the ignition switch is off and secondly maintain the RCM at its original horizontal position when connected because any modification to the position poses a significant risk of Safety Canopy(R) deployment leading to fatal injuries. The RCM and impact sensor mounting areas should be checked for deformation after any crash incident because new parts must be installed under all circumstances regardless of air bag deployment status. Run Programmable Module Installation (PMI) during new RCM installation to eliminate system failure occurrences. Before disconnection of the large RCM electrical connector through the thumb tab press and connector position assurance lever pivot you must depower the Supplemental Restraint System (SRS). After RCM extraction install the new unit using 12 Nm (106 lb-in) torque for right-hand bolts and the left-hand bolt to match this value. The proper alignment of the large RCM connector should be verified prior to connection by applying gentle force until an audible click forms and finally locking it with the connector position assurance lever. The SRS system should be powered up without immediate proof testing followed by completion of the PMI procedure when installing a new RCM. The verification of SRS functions requires a sequence of switching the ignition from ON to OFF and waiting 10 seconds before returning it to ON while watching the air bag warning indicator which should activate for 6 seconds before shutting off. Further inspection is necessary for the warning indicator when it fails to illuminate or stays on continuously or flashes at 5 Hz rate. The process needs all persistent Diagnostic Trouble Codes (DTCs) to be eliminated from both the RCM and Occupant Classification System Module (OCSM) through scan tool diagnostics.

The service of air bag control modules requires safety glasses to prevent injuries that may occur from accidental air bag activation. A correct orientation of the restraints control module (RCM) is necessary for proper air bag operation thus inspect the RCM mounting and bracket for deformation after any collision that damaged the center tunnel area; replace the module if it shows any damage. The use of memory saver devices to protect from personal injuries should be avoided by technicians. Vehicle owners should install the appropriate RCM because safety curtain and side air bag version connectors differ from standard models while connector force can damage the system. The modules inside your vehicle exhibit sensitivity to static electricity therefore proper protection measures should always be followed. Prepare all new configuration data through the diagnostic tool before removing the module to use during the new module installation. A warning lamp from the RCM fuse becomes activated during ignition ON conditions but signifies only a normal system state without any failure. It is crucial that the SRS functions without flaws when the customer receives the vehicle and new part replacements must be used for all repairs. The sequence to remove the RCM consists of these steps: depower the system, remove the two right-hand side retaining bolts, arrange the carpet one way, disconnect the big connector along with the small connector and completely extract the module from its location. Total Installation success requires new RCM configuration before mounting followed by retaining bolt tightening to 12 Nm (9 lb-ft). First align the large connector and then connect the small electrical connector while applying light force so that the position assurance lever can be engaged. An operator should execute a download of saved configuration information to the new RCM after finishing SRS repowering. The verification process for the SRS begins by turning ignition from ON to OFF for 10 seconds before returning to ON position while checking the air bag indicator which will stay on for around 6 seconds before turning off. When the indicator fails to show light or stays lit or flashes at 5 Hz rate it is necessary to diagnose and rectify any existing faults. A diagnostic tool should be used to erase all ongoing diagnostic trouble codes that exist in both RCM and occupant classification sensor (OCS) modules.
