WARNING: This page is about a different car, the 2004 Ford Escape, 2003 Ford Escape, and 2002 Ford Escape. However, it is still accessible from the selected car via links, so may be relevant.
  1. Connect New Generation Star (NGS) tester to Data Link Connector (DLC). Turn ignition switch to RUN position. Using NGS tester, perform Powertrain Control Module (PCM) self-test. If no DTCs exist, go to next step. If any DTCs exist, perform appropriate test. See DIAGNOSTIC TROUBLE CODE DEFINITIONS  under SELF-DIAGNOSTIC SYSTEM.
  2. Turn ignition switch to LOCK position. Disconnect NGS tester. Disconnect generator 3-pin harness connector. Connect a fused (15-amp) jumper wire between ground and generator harness connector terminal No. 1 (Gray/Orange wire). See Figure. Turn ignition switch to RUN position. If warning indicator does not illuminate, go to next step. If warning indicator illuminates, replace generator.
  3. Disconnect PCM harness connector. Inspect connector for corrosion and pushed out pins. Connect PCM harness connector. Ensure connector is seated properly. Operate system. If problem still exists, replace PCM. If system is operating properly, problem may have been caused by a loose or corroded connector. Clear DTCs. Repeat PCM self-test.
