Measure voltage between ground and terminal No. 9 (Pink wire) at instrument cluster harness connector C1. See Figure . If voltage is less than 10 volts, repair open in Pink wire. Perform BODY VERIFICATION TEST  under VERIFICATION TESTS. If voltage is 10 volts or greater, go to next step.
  4. Turn ignition switch to OFF position. Remove fuse No. 16 (15-amp) from power distribution center. Measure resistance between ground and terminal No. 9 (Pink wire) at instrument cluster harness connector C1. If resistance is less than 5 ohms, repair short to ground in Pink wire. Replace fuse.
