Test 2: Cruise Control Indicator Does Not Illuminate

WARNING: This page is about a different car, the 2002 Mazda 626. However, it is still accessible from the selected car via links, so may be relevant.
  1. Inspect METER (10-amp) fuse. If fuse is okay, go to next step. Replace fuse if faulty, then retest cruise control system. If fuse blows immediately, go to next step.
  2. Turn ignition off. Disconnect cruise control actuator harness, then turn ignition on. Using DVOM, measure voltage between cruise control actuator harness terminal "J" (White/Blue wire) and ground. If battery voltage is present, replace cruise control actuator. See ACTUATOR  under REMOVAL & INSTALLATION. Retest system. If voltage is not present, go to next step.
  3. Remove instrument cluster. See INSTRUMENT CLUSTER REMOVAL & INSTALLATION. Inspect cruise control indicator bulb and bulb connector. Repair if necessary, then retest cruise control system. If bulb is okay, go to next step.
  4. Measure voltage between instrument cluster terminal 3N (Yellow/Red wire) and ground. See Figure . If voltage is present, go to next step. If voltage is not present, repair wiring between METER (10-amp) fuse and instrument cluster. See INSTRUMENT CLUSTER REMOVAL & INSTALLATION.
  5. Turn ignition off. Check continuity between instrument cluster harness terminal 1J (White/Blue wire) and ground. If continuity exists, repair wiring harness between instrument cluster and cruise control actuator. See WIRING DIAGRAMS  . If continuity does not exist, replace instrument cluster. Then retest cruise control system.
