TEST VER-3ASPEED CONTROL VERIFICATION
Inspect the vehicle to ensure that all engine components are connected. Reassemble and reconnect
all components as necessary.
If the engine control module has been changed, do the following:
1. If the vehicle is equipped with a factory theft alarm, start the vehicle at least 20 times so that
the alarm system may be activated when desired.
Connect the DRB to the data link connector and erase the codes.
Ensure no other speed control problems remain by doing the following:
1. Road test the vehicle at a speed above 35 mph.
2. Turn the speed control ON/OFF switch to the ON position.
3. Depress and release the SET switch. If the speed control did not engage, the repair is not
complete.*
4. Quickly depress and release the RESUME/ACCEL switch. If the vehicle speed did not increase
by 2 mph, the repair is not complete.*
5. Using caution, depress and release the brake pedal. If the speed control did not disengage, the
repair is not complete.*
6. Bring the vehicle speed back up to 35 mph.
7. Depress the RESUME/ACCEL switch. If the speed control did not resume the previously set
speed, the repair is not complete.*
8. Hold down the DECEL switch. If the vehicle did not decelerate, the repair is not complete.
9. Ensure the vehicle speed is greater than 35 mph and release the SET switch. If the vehicle did
not adjust and set a new vehicle speed, the repair is not complete.*
10. With Speed Control engaged, depress the ON/OFF switch. If the speed control did not
disengage, the repair is not complete.*
If the vehicle successfully passed all of the previous tests, the speed control system is now
functioning as designed. The repair is now complete.
*Check for Technical Service Bulletins that pertain to this speed control problem and then, if
necessary, return toDTC TEST.
