Multifunction Electronic Modules: Removal & Installation Mercury Mountaineer III

REMOVAL

Note. The steps included in the SJB removal and installation procedure are critical to restoring the vehicle security and tire pressure monitoring systems to normal operation. A new SJB is delivered in manufacturing mode with 6 preset diagnostic trouble codes (DTCs) related to the tire pressure monitoring system. The presence of these DTCs requires the installation procedures be followed in order to clear the DTCs and enable normal SJB operations.

Note. Prior to the removal of the SJB, it is necessary to upload the module configuration information to the diagnostic tool. This information must be downloaded to the new SJB after installation. For additional information, refer to MODULE CONFIGURATION .

1. Remove the driver door scuff plate. For additional information, refer to «INTERIOR TRIM AND ORNAMENTATION»(ref-270927) .
2. Position the LH door opening weather seal aside.
3. Remove the push pin and the cowl side trim panel.
4. Remove the 2 bolts and the parking brake release handle.
5. Disconnect the parking brake switch electrical connector.
