Pickup & Pathfinder

  1. To check power source, turn ignition switch to "ON" position. On models equipped with voltmeter, check voltage between terminal No. 2 and ground. On models without voltmeter, check voltage between terminal No. 29 and ground. On all models, if 12 volts is present go to step 3).
  2. If 12 volts is not present, check for blown fusible link or fuse. Check harness continuity between battery terminal and combination meter. Check for malfunctioning ignition relay and/or ignition switch.
  3. To check voltage output, measure voltage between terminal "B" and ground. See Figure thru Figure. If there is not about 8 volts, check voltage regulator and/or printed circuit. If there is 8 volts, connect a jumper wire between terminal "C" and ground for less than 10 seconds.
  4. Fuel gauge should move smoothly from "EMPTY" to "FULL". If it does not, replace fuel gauge. If it does, perform FUEL TANK SENDING UNIT TEST . If sending unit is okay, repair or replace harness between combination meter and fuel gauge unit harness.
