Instrument Cluster Ecu Power Source Circuit

  1. Check GAUGE, MPX-B and DOME fuses (10-amp). Repair as necessary. If fuses are okay, go to next step.
  2. Remove instrument cluster. With harness connectors disconnected, measure voltage between terminals No. 13 (Green/White wire) and No. 22 (White/Black wire) at instrument cluster harness connector "A". See Figure. If battery voltage is present, go to next test listed in SYMPTOM DIAGNOSIS (INDICATORS & WARNING LIGHTS)  table under TROUBLE SHOOTING. If battery voltage is not present, repair open in appropriate circuit between instrument cluster and ECM. See WIRING DIAGRAMS .
