Using Cruise Control Light
- 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.
- 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.
- 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.
- 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.
- 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.
- 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.
- 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.
- 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.
- 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.
- 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.
