Test J: Memory Seat Inoperative Using Remote Transmitter

CAUTION: Side air bag system must be deactivated for diagnosis of power seat (if equipped). See AIR BAG RESTRAINT SYSTEMS - EXPLORER & MOUNTAINEER article. Air Bag Simulator (418-F088) must be installed under seats to floor connector, and removed before operating vehicle.

NOTE: Before beginning this test, ensure seat and seat track are free from all obstructions.

Deactivate air bag system. See AIR BAG RESTRAINT SYSTEMS - EXPLORER & MOUNTAINEER article. Ensure transmission is in Park. Turn ignition switch to LOCK position. Connect New Generation Star (NGS) tester to Data Link Connector (DLC). Retrieve and record continuous DTCs. Clear continuous DTCs. Perform Driver's Seat Module (DSM) self-test. If no DTCs were retrieved during self-test, go to next step. If any DTCs were retrieved during self-test, perform appropriate test. See DRIVER'S SEAT MODULE DIAGNOSTIC TROUBLE CODE INDEX table under SELF-DIAGNOSTIC SYSTEM.
Disconnect memory switch 10-pin harness connector C511. Disconnect Remote Anti-Theft Personality (RAP) module 22-pin harness connector C338. RAP module is located behind left rear quarter panel. Measure resistance of Brown/Light Green wire between memory switch harness connector C511 terminal No. 4 and RAP module harness connector C338 terminal No. 6. See Figure and Figure . Measure resistance of Black/Orange wire between memory switch harness connector C511 terminal No. 3 and RAP module harness connector C338 terminal No. 18. If resistance is 5 ohms or more in either measurement, repair open in appropriate wire(s). If resistance is less than 5 ohms in both measurements, check for open and/or short circuits in remote keyless entry system. See REMOTE KEYLESS ENTRY SYSTEMS - EXPLORER & MOUNTAINEER article.
