Diagnostic Module

For front impact severity sensor servicing the driver should use safety glasses to protect themselves from accidental air bag deployment incidents. Vehicle sensor orientation must be checked to maintain proper system functioning while inspections of sensor mounting brackets and supplemental restraint wiring pigtail happen for deformation and all damaged components need proper replacement before sensor installation even if air bags did not trigger. Memory saver devices should never be utilized because they create safety hazards for humans. The air bag warning lamp turns on during this condition because of the removed RCM fuse when the ignition switch is ON. This normal state does not indicate any problems with the supplemental restraint system. Check that the SRS functions properly along with its faultless operation before handing over the vehicle to customers. The repair work should start with new part installation followed by original part reinstallation when the issue remains to perform diagnostic check again. Begin with depowering the system before unfastening the top radiator grille screws while pulling it forwards to unlock lower mounting clips. The front air foil needs to be lowered and the electrical connector must be detached from the front impact severity sensor before sensor boltted access becomes possible. The correct system operation depends on tightening every retaining bolt of the front impact severity sensor to 12 Nm (9 lb-ft) while maintaining clean and debris-free surfaces between the sensor and radiator support. Recharge the system following the reverse order of uninstallation then replace the sensor along with its two bolts.

Safety glasses should always be worn when servicing the air bag control module to prevent injuries from possible accidental deployment. A correct orientation of the restraints control module (RCM) ensures proper air bag deployment in any situation but checking the mounting and bracket for deformation becomes necessary after a collision damages the driver seat floor area. Replace the RCM immediately in such cases. The RCM installation area needs to maintain its original state and you should never employ memory saver devices to decrease personal injury threats. Start the process of disconnection or reconnection of RCM electrical connectors by depowering the SRS and securely anchoring the RCM along with its bracket to the floor pan to safeguard against damage. The RCM fuse removal with ON ignition turns on the air bag warning lamp but this illumination is normal and means no faults exist. The SRS component requires depowering during all seat-related servicing operations. Verification of the installed RCM together with functional SRS testing and absence of faults must be completed before returning the vehicle to its customer. Replace each faulty part with new components yet return the original part in case the problem persists beforehand conducting another diagnostic check. The processing sequence begins with depowering the system followed by removing the driver seat and prying from the sides to get rid of the RCM cover clips before pulling it backward. Cleared the large RCM electrical connector through lever disengagement beginning at the thumb tab followed by pivot positioning of the connector assurance lever backward while removing it from its socket. Detach the small RCM electrical connector before unfastening the three bolts securing both RCM and bracket assembly. The RCM bracket retaining bolts require a torque of 12 Nm (9 lb-ft) but inspection for any corrosion should happen first. Connect the small RCM electrical connector only after the large RCM connector position assurance lever is completely open and released to do so. When installing the large RCM electrical wiring connector avoid angling it to prevent bad connections and component damage since light pressure should be used before using the lever for full connector seating. To complete the process install the RCM cover while reinstalling the driver seat then power on the system.

Workers should wear safety glasses during air bag control module servicing steps to protect themselves from possible air bag deployments that could result in injury. Complete air bag functionality depends on the correct orientation of the restraints control module (RCM) while any damage in the driver seat floor area following a crash demands complete examination of mounting and bracket systems; an RCM replacement is mandatory even if air bags have not deployed. The area surrounding the RCM needs to be put back to its original state while memory saver devices should not be used because they increase personal injury risks. The RCM along with its bracket must be fastened to the floor pan and SRS depowering should happen before electrical connector handling to protect the RCM from static damage that affects electronic components. The air bag warning lamp will turn on when the RCM fuse is removed with the ignition switch ON yet this operation indicates no fault exists. Service a seat that has SRS components by power-down the SRS system while installing only the correct RCM to prevent reading incorrect DTCs. Returning a vehicle to the customer requires that the SRS operates properly with no detected faults. Repair procedures begin by installing new parts while you should return to the diagnostic process if the problem continues even with reinstallation of the original component. The procedure starts with system depowering before removing the driver seat and methodically unfastening the RCM cover through outward clipping while pushing it backward. Unplug the large RCM electrical connector through the tab pinch method followed by rotating the connector position assurance lever until you can easily remove the connector. The RCM assembly requires removal of its small electrical connector before extracting the bracket retaining bolts. The RCM bracket retaining bolts need 12 Nm (9 lb-ft) torque setting when installing them yet check for any corrosion first. Complete installation of the large RCM electrical connector by letting go the position assurance lever before linking the small RCM electrical connector. During installation do not angle the large RCM electrical wiring connector to stop bad connections and component damage then position the connector lightly before using the lever for complete seating. Conclusion of the procedure involves placing the RCM cover properly while repositioning the driver seat and restoring system power.

Confirm that the SRS is fully operational and free of faults.
