Test P: Right Turn Indicator Never/Always On

  1. Turn ignition switch to RUN position. Place multifunction switch in right turn position. If right turn signals operate properly, go to next step. If right turn signals do not operate properly, repair turn signals as necessary. See appropriate wiring diagram in EXTERIOR LIGHTS article.
  2. Turn ignition switch to RUN position. If right turn indicator is on at all times, go to next step. If right turn indicator is not on at all time, go to step  5 .
  3. Turn ignition switch to LOCK position. Disconnect multifunction switch harness connector C269. Turn ignition switch to RUN position. Measure voltage at terminal No. 5 (White/Light Blue wire) at multifunction switch harness connector C269. See Figure . If voltage is greater than 5 volts, go to next step. If voltage is 5 volts or less, replace multifunction switch.
  4. Turn ignition switch to LOCK position. Disconnect instrument cluster harness connector C251. Turn ignition switch to RUN position. Measure voltage at terminal No. 5 (White/Light Blue wire) at multifunction switch harness connector C269. If voltage is greater than 5 volts, repair short to voltage in White/Light Blue wire. If voltage is 5 volts or less, replace instrument cluster printed circuit.
  5. Turn ignition switch to LOCK position. Disconnect instrument cluster harness connector C251. Turn ignition switch to RUN position. Place multifunction switch in right turn position. Measure voltage at terminal No. 12 (White/Light Blue wire) at instrument cluster harness connector C251. See Figure . If voltage is greater than 10 volts, go to next step. If voltage is 10 volts or less, go to step  7 .
  6. Check continuity across right turn indicator bulb. If continuity exists, replace instrument cluster printed circuit. If continuity does not exist, replace bulb.
  7. Disconnect multifunction switch harness connector C269. Measure resistance in White/Light Blue wire between terminal No. 12 at instrument cluster harness connector C251 and terminal No. 5 at multifunction switch harness connector C269. See Figure and Figure . If resistance is 3 ohms or less, replace multifunction switch. If resistance is greater than 3 ohms, repair open in White/Light Blue wire.
