Test G: Instrument Cluster Module Does Not Respond To NGS Tester
WARNING: This page is about a different car, the 2002 Ford Pickup. However, it is still accessible from the selected car via links, so may be relevant.
- Turn ignition switch to LOCK position. Disconnect instrument cluster White 22-pin harness connector C220b. Inspect harness connector for damage. If harness connector is okay, go to next step. If harness connector is damaged, repair as necessary.
- Measure resistance in Tan/Orange wire between instrument cluster harness connector C220b terminal No. 1 and Data Link Connector (DLC) terminal No. 2. Measure resistance in Pink/Light Blue wire between instrument cluster harness connector C220b terminal No. 2 and DLC harness connector terminal No. 10. See Figure and Fig 1 . If both resistances are 5 ohms or less, replace instrument cluster and perform data link diagnostics. See INSTRUMENT CLUSTER in REMOVAL & INSTALLATION. See DATA LINK DIAGNOSTIC TEST . If either resistance is more than 5 ohms, repair Tan/Orange wire and/or Pink/Light Blue wire between instrument cluster and DLC. See WIRING DIAGRAMS .
