Driver's Seats With Memory

Connect NGS tester to Data Link Connector (DLC) located below instrument panel. Using NGS tester, perform data link diagnostic test. See DATA LINK DIAGNOSTIC TEST under SELF-DIAGNOSTIC SYSTEM in MODULE COMMUNICATIONS NETWORK - EXPLORER & MOUNTAINEER article. If NGS tester displays CKT 914, CKT 915 or CKT 70=ALL ECUS NO RESP/NOT EQUIP, repair module communications concern. See MODULE COMMUNICATIONS NETWORK - EXPLORER & MOUNTAINEER article. If NGS tester displays NO RESP/NOT EQUIP for Driver's Seat Module (DSM), perform TEST K: NO COMMUNICATION WITH DRIVER'S SEAT MODULE (DSM) under SYSTEM TESTS.
If NGS tester displays SYSTEM PASSED for DSM, retrieve and record continuous DTCs using NGS tester. Erase continuous DTCs. Using NGS tester, perform DSM self-test. If any DSM DTCs are retrieved, perform appropriate test under SYSTEM TESTS. See DRIVER'S SEAT MODULE (DSM) DTC INDEX table. If no DTCs are retrieved, repair by symptom. See SYMPTOM INDEX table under SYSTEM TESTS.
