Test 5B - ELEC Instrument Cluster Shorted Fuel Gauge CKT
WARNING: This page is about a different car, the 1994 Plymouth Acclaim, 1994 Dodge Spirit, and 1994 Chrysler LeBaron. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:
For connector terminal identification, see CONNECTOR IDENTIFICATION. For wiring diagram, see WIRING DIAGRAMS. After each repair, perform TEST VER-1.
- Disconnect fuel tank sending unit connector. See Figure . Turn ignition switch to ON position. If fuel gauge reads empty, go to step 4). If fuel gauge does not read empty, turn ignition switch to OFF position. Go to next step.
- Disconnect traveler module 7-pin connector. See Figure . Turn ignition switch to ON position. If fuel gauge reads empty, replace traveler module. If fuel gauge does not read empty, turn ignition switch to OFF position. Go to next step.
- Disconnect Electronic Instrument Cluster (EIC) Red 13-pin connector. Using DRB in ohmmeter mode, check resistance of EIC Red 13-pin connector terminal No. 9 (Dark Blue wire). If resistance is less than 5 ohms, repair short to ground in Dark Blue wire. If resistance is more than 5 ohms, replace EIC.
- Reconnect fuel tank sending unit connector. Ensure ignition switch is in ON position. Record fuel gauge position. Turn ignition switch to OFF position. Disconnect Electronic Instrument Cluster EIC Red 13-pin connector. See Figure . Disconnect traveler module 7-pin connector. See Figure . Go to next step.
- Using DRB in ohmmeter mode, measure resistance at traveler module connector terminal No. 6 (Dark Blue wire). If fuel gauge position matches resistance reading, replace EIC. See FUEL TANK SENDING UNIT RESISTANCE SPECIFICATIONS table. If fuel gauge position does not match resistance reading, replace fuel tank sending unit.
