Using Cruise Control Light

  1. Turn ignition switch to ON position. Turn cruise control main switch on. Ensure cruise indicator light illuminates. If cruise indicator light does not illuminate, service before continuing.
  2. Press and hold RESUME/ACCEL switch for at least 3 seconds. Cruise indicator light will illuminate for 3 seconds, and then go out for 2 seconds. Cruise indicator light will flash condition detection mode output patterns. On 2-digit output patterns, a short pause separates each digit of output pattern (example of 15: long flash, short pause, 5 short flashes). If no DTCs are present, light will not flash. Go to step  10 . If any DTCs are present, go to next step.
  3. If DTC 01 does not exist, go to next step. If DTC 01 exists, check actuator circuit. See DTC 01: ACTUATOR CIRCUIT  under CIRCUIT TESTS.
  4. If DTC 05 does not exist, go to next step. If DTC 05 exists, check brake switch circuit. See DTC 05: BRAKE SWITCH  under CIRCUIT TESTS.
  5. If DTC 07 does not exist, go to next step. If DTC 07 exists, check brake switch circuit. See DTC 07: BRAKE SWITCH  under CIRCUIT TESTS.
  6. If DTC 11 does not exist, go to next step. If DTC 11 exists, check cruise control switch circuit. See DTC 11: CRUISE CONTROL SWITCH (SET/COAST SWITCH)  under CIRCUIT TESTS.
  7. If DTC 12 does not exist, go to next step. If DTC 12 exists, check cruise control switch circuit. See DTC 12: CRUISE CONTROL SWITCH (RESUME/ACCEL SWITCH)  under CIRCUIT TESTS.
  8. If DTC 13 does not exist, go to next step. If DTC 13 exists, check cruise control switch circuit. See DTC 13: CRUISE CONTROL SWITCH (GROUND CIRCUIT)  under CIRCUIT TESTS.
  9. If DTC 15 does not exist, no DTCs exist at this time. Go to next step. If DTC 15 exists, see DTC 15: CRUISE CONTROL MODULE  under CIRCUIT TESTS.
  10. To cancel condition detection mode, drive vehicle at a speed greater than 10 MPH or turn cruise control main switch off. Ensure cruise indicator light goes out.
