2.5TL & 3.2TL

  1. Disable air bag system. See appropriate AIR BAG RESTRAINT SYSTEMS article in the ACCESSORIES/SAFETY EQUIPMENT section. Remove instrument panel lower cover and knee bolster. Turn ignition switch to OFF position. Disconnect cruise control unit Gray 14-pin connector. See CRUISE CONTROL UNIT GRAY 14-PIN CONNECTOR TERMINAL ID (2  .5TL & 3.2TL) table. Also, see Fig 1 . Ensure connector terminals are not bent, loose or corroded. Repair as necessary and recheck system.
  2. Turn ignition on. Push cruise control main switch to ON position. Depress and release brake pedal. Measure voltage at cruise control unit Gray 14-pin connector terminal No. 2 (Gray wire). Battery voltage should exist when brake pedal is released and zero volts should exist when brake pedal is depressed. If voltage is as specified, go to next step. If voltage is not as specified, check brakelight switch. See BRAKELIGHT SWITCH  under COMPONENT TESTING. Check for an open, or loose or disconnected terminals in Gray wire between cruise control unit and brakelight switch. See WIRING DIAGRAMS  .
  3. Turn ignition off. Using an ohmmeter, check for continuity between cruise control unit Gray 14-pin connector terminal No. 3 (Black wire) and ground. If continuity exists, go to next step. If continuity does not exist, check for an open, or loose or disconnected terminals in Black wire between cruise control unit and ground connection located behind left kick, below hood release. See WIRING DIAGRAMS  .
  4. Measure voltage at cruise control unit Gray 14-pin connector terminal No. 4 (Green/White wire). Depress and release brake pedal. Battery voltage should exist when brake pedal is depressed and zero volts should exist when brake pedal is released. If voltage is as specified, go to next step. If voltage is not as specified, check brakelight switch. See BRAKELIGHT SWITCH  under COMPONENT TESTING. Check for an open circuit, or loose or disconnected terminals in Green/White wire between cruise control unit and brakelight switch.
  5. Measure voltage at cruise control unit Gray 14-pin connector terminal No. 5 (Light Green/Red wire). Depress SET button. If battery voltage exists, go to next step. If battery voltage does not exist, check fuse No. 30 (20-amp) on 2.5TL or fuse No. 39 (20-amp) on 3.2TL, located in engine compartment fuse/relay box. Check SET/RESUME/CANCEL switch. See SET/RESUME/CANCEL SWITCH  under COMPONENT TESTING. Check horn relay and clockspring. Check for an open, or loose or disconnected terminals in Light Green/Red wire between cruise control unit and clockspring.
  6. Measure voltage at cruise control unit Gray 14-pin connector terminal No. 6 (Light Green/Black wire). Depress RESUME button. If battery voltage exists, go to next step. If battery voltage does not exist, check fuse No. 30 (20-amp) on 2.5TL or fuse No. 39 (20-amp) on 3.2TL, located in engine compartment fuse/relay box. Check SET/RESUME/CANCEL switch. See SET/RESUME/CANCEL SWITCH  under COMPONENT TESTING. Check horn relay and clockspring. Check for an open circuit, or loose or disconnected terminals in Light Green/Black wire between cruise control unit and clockspring.
  7. Using a fused jumper wire, connect battery voltage to cruise control unit Gray 14-pin connector terminal No. 8 (Brown wire). Using another jumper wire, ground connector terminal No. 10 (Brown/Black wire). If cruise control actuator motor can be heard operating, go to next step. If actuator motor does not operate, check cruise control actuator. See CRUISE CONTROL ACTUATOR ASSEMBLY  under COMPONENT TESTING. Check for an open, or loose or disconnected terminals in Brown wire or Brown/Black wire between cruise control unit and cruise control actuator. See WIRING DIAGRAMS  .
  8. Turn ignition on. Using jumper wire, ground cruise control unit Gray 14-pin connector terminal No. 9 (Blue/Black wire). If instrument cluster cruise indicator light illuminates, go to next step (on 3.2TL, go to step 10). If cruise indicator light does not illuminate, check bulb. Check fuse No. 1 (10-amp) in fuse/relay box located under instrument panel. Check dimming circuit. See appropriate INSTRUMENT PANELS article in the ACCESSORIES/SAFETY EQUIPMENT section. Check for an open, or loose or disconnected terminals in Blue/Black wire between cruise control unit and instrument cluster.
  9. On 2.5TL, turn ignition on. Using a voltmeter, measure voltage at cruise control unit Gray 14-pin connector terminal No. 11 (Black/Yellow wire). If battery voltage exists, go to next step. If battery voltage does not exist, check fuse No. 4 (20-amp) in fuse/relay box located under instrument panel. Check for an open circuit, or loose or disconnected terminals in Black/Yellow wire between cruise control unit and fuse No. 4. See WIRING DIAGRAMS  .
  10. Raise and support front of vehicle. Turn ignition on. Push cruise control main switch to ON position. Connect analog voltmeter positive lead to cruise control unit Gray 14-pin connector terminal No. 12 (Orange wire) and negative lead to terminal No. 3 (Black wire). Block one front wheel, slowly rotate opposite wheel and measure voltage. Voltage should pulse between zero and 5 volts or more. If voltage is as specified, go to next step. If voltage is not as specified, check Vehicle Speed Sensor (VSS). See appropriate INSTRUMENT PANELS article in the ACCESSORIES/SAFETY EQUIPMENT section. Check for an open circuit, or loose or disconnected terminals in Orange wire between cruise control unit and VSS. Check for an open, or loose or disconnected terminals in Black wire between cruise control unit and ground connection located behind left kick panel, under hood release.
  11. Turn ignition on. Push cruise control main switch to ON position. Using a voltmeter, measure voltage between cruise control unit Gray 14-pin connector terminal No. 13 (Light Green wire) and ground. If battery voltage exists, go to next step. If battery voltage does not exist, check fuse No. 4 (15-amp) in fuse/relay box located under instrument panel. Check main switch. See MAIN SWITCH  under COMPONENT TESTING. Check for an open, or loose or disconnected terminals in Light Green wire between cruise control unit and cruise control main switch.
  12. Turn ignition off. Using an ohmmeter, check for continuity between cruise control unit Gray 14-pin connector terminal No. 14 (Pink wire) and ground. Move gearshift lever to "2", "D" or "D4" positions. Continuity should exist with gearshift lever in any specified position. Continuity should not exist in any other position. If continuity is as specified, replace cruise control unit and recheck system. If continuity is not as specified, check gearshift position switch. See GEARSHIFT POSITION SWITCH  under COMPONENT TESTING. Check for an open, or loose or disconnected terminals in Pink wire between cruise control unit and gearshift position switch. Refer to the WIRING DIAGRAMS  .
