Always position driver air bag modules properly for servicing by directing the air bag main component along with deployment door and trim cover or tear seam toward the opposite direction from your body while never placing the module down with the deployment door facing the floor to prevent severe injuries. Probing the electrical connectors on air bag modules should never be attempted because accidental deployment functions could harm individuals with possibly fatal consequences. When air bag modules display discolored or damaged trim covers or deployment doors it is necessary to replace the module with a new one to guarantee proper deployment. The installation of memory saver devices raises the danger of unintended deployment so they should be avoided. The restrictions control module (RCM) air bag warning indicator becomes visible during this state because the RCM fuse is present while the ignition switch remains in the ON position. This normal warning does not imply any system malfunction. All SRS operations need to function normally and show no faults before you send the vehicle to market. The maintenance process should start with installing fresh components until the original items can be replaced to complete the diagnostic testing step once more. Begin by depowering the SRS system and unscrew the three screws attached to the steering column cover then detach the lower steering column shroud by unfastening its three screws and upper shroud untaped clamps. The process continues with removing the two screws from the instrument cluster finish panel then prying it forward together with disconnecting the in-vehicle temperature sensor assembly if present. Discard the instrument cluster finish panel with upper steering column shroud assembly after adjusting the steering column to reach maximum tilt-down position. Before removing the driver air bag module one must position the
Steering Wheel to the 12 o'clock and 6 o'clock positions to access wire clips then unclip those wires from the attachment pins while lifting the module from the steering wheel. Extract electrical connections by disconnecting the two retainers attached to each device module. When installing the vehicle ensure each wire clip is placed properly on the steering wheel but you can adjust their position if needed. Steer away the steering wheel control cables from areas where driver air bag module pins anchor to stop cable pinching when you install the system. Install the two specific electrical connectors onto the driver air bag module while making sure they fit together with the intended keyway pattern without forced insertion. The correct positioning of wire clips requires removal of the driver air bag module for installation. The driver air bag module installation requires pushing it toward the steering wheel until the wire clips achieve complete engagement. Then check their securement with a mirror. The driver air bag module requires strong pulling motions from each corner for the correct attachment. Put back the instrument cluster finish panel and steering column upper shroud while connecting the in-vehicle temperature sensor assembly (when present). The instrument cluster finish panel should be secured through screws followed by installation of the lower steering column shroud through three screws then ending with the steering column cover which requires three screws. Verifying the horn operation requires checking each corner of the driver air bag module using the SRS power. Discontinue the check if the horn fails to work so inspect the horn contacts along with the steering wheel switches connector and horn wire connectors for correct attachment. Then proceed with horn fault diagnostics.
