Using Cruise Indicator Light
NOTE:
If RESUME/ACCEL switch is malfunctioning, cruise indicator light will not provide a correct indication when cruise system is inspected. Use NGS tester procedure.
NOTE:
Cruise indicator light will flash output patterns during this next procedure. A long pause separates each output pattern. On 2-digit output patterns, a short pause separates each digit of output pattern (for example: 2 long flashes, pause, then 1 short flash indicates output pattern 21). If no output pattern is present, light will not flash.
- Turn ignition switch to RUN position. Ensure cruise control main switch is off. Press and hold cruise control RESUME/ACCEL switch then press cruise control main switch to activate system inspection. Cruise indicator light should illuminate for 3 seconds.
- Press SET/COAST switch. If output pattern 21 is retrieved, go to next step. If output pattern 21 is not retrieved, check cruise control switch circuit. See CRUISE CONTROL SWITCH CIRCUIT under CIRCUIT TESTS.
- Press RESUME/ACCEL switch. If output pattern 22 is retrieved, go to next step. If output pattern 22 is not retrieved, check cruise control switch circuit. See CRUISE CONTROL SWITCH CIRCUIT under CIRCUIT TESTS.
- Depress brake pedal. If output pattern 31 is retrieved, go to next step. If output pattern 31 is not retrieved, check brake switch circuit. See BRAKE SWITCH CIRCUIT under CIRCUIT TESTS.
- Place gear selector in Park or Neutral. If output pattern 35 is retrieved, go to next step. If output pattern 35 is not retrieved, check transmission range switch circuit. See TRANSMISSION RANGE (TR) SWITCH CIRCUIT under CIRCUIT TESTS.
- Drive vehicle at a speed greater than 25 MPH. If output pattern 37 is retrieved, operation mode has passed. Perform condition detection mode. See CONDITION DETECTION MODE . If output pattern 37 is not retrieved, check vehicle speed sensor circuit. See VEHICLE SPEED SENSOR CIRCUIT under CIRCUIT TESTS.
