Speed Control Verification

Use this test to verify that the Speed Control symptom has been repaired and that the vehicle can be returned to the customer.

Note: If the Powertrain Control Module has been replaced and the correct VIN and mileage have not been programmed, a DTC will be set in the ABS, Airbag and the SKIM modules. In addition, if the vehicle is equipped with a Sentry Key Immobilizer Module (SKIM), Secret Key data must be updated to enable starting.

1. Inspect the vehicle to ensure that all components related to the repair are connected properly.

2. With the DRB III, clear DTC's.

3. Road test the vehicle at a speed above 35 mph.

4. Turn the Speed Control ON.

5. Press and release the SET switch. Verify that the Speed Control engages.

6. With the Speed Control engaged:

a. Press and hold the ACCEL switch. Verify that the vehicle speed increases.

b. Press and hold the SET (or DECEL) switch. Verify that the vehicle speed decreases.

c. Press and release the CANCEL switch. Verify that the Speed Control disengages.

d. Allow the vehicle speed to drop below 25 mph. Press and release the RESUME switch. Verify that the previously set vehicle speed is attained.

e. Using caution, press and release the brake pedal. Verify that the Speed Control disengages.

f. Increase vehicle speed by at least 10 mph. Press and release the SET switch. Verify that the Speed Control maintains this speed.

g. Press and release the ON/OFF switch (turn the Speed Control OFF.) Verify that the Speed Control disengages.

If any or all of these functions are not operating properly, refer to the symptom list for the appropriate diagnostic testing procedures.

7. With the DRB III, read DTC's. If the DTC returns, or any other symptom or DTC is present, refer to the symptom list for further diagnostic testing procedures. Check for any Technical Service Bulletins that may apply.

8. If there are no DTC's present and all components are functioning properly, the repair is complete.
