T

, erase DTCs.

6. If the ECM has been replaced, perform steps 11 through 13, then continue with the verification.

7. If ECM has been changed and correct VIN and mileage have not been programmed, a DTC will be set in ABS
and Air bag modules. In addition, if vehicle is equipped with a Sentry Key Immobilizer Module (SKIM), Secret Key
data must be updated to enable start.

8. For ABS and Air Bag systems: Enter correct VIN and Mileage in ECM. Erase codes in ABS and Air Bag modules.

9. For SKIM theft alarm: Connect DRBIII

T

to data link conn. Go to Theft Alarm, SKIM, Misc. and place SKIM in

secured access mode, by using the appropriate PIN code for this vehicle. Select Update the Secret Key data. Data
will be transferred from SKIM to PCM

10. Turn the speed control ON (if equipped, cruise light will be on).

11. Depress and release the SET Switch. If the speed control did not engage, the repair is not complete. Check for
TSBs that pertain to speed control problem and then, if necessary, return to Symptom List.

12. Depress and hold the RESUME/ACCEL Switch. If the vehicle speed did not increase by at least 2 mph, the
repair is not complete. Check for TSBs that pertain to speed control problem and then, if necessary, return to Symp-
tom List.

13. Press and hold the COAST switch. The vehicle speed should decrease. If it did not decrease, the repair is not
complete. Check for TSBs that pertain to speed control problem and then, if necessary, return to Symptom List.

14. Using caution, depress and release the brake pedal. If the speed control did not disengage, the repair is not
complete. Check for TSBs that pertain to speed control problem and then, if necessary, return to Symptom List.

15. Bring the vehicle speed back up to 35 MPH.

16. Depress the RESUME/ACCEL switch. If the speed control did not resume the previously set speed, the repair
is not complete. Check for TSBs that pertain to speed control problem and then, if necessary, return to Symptom
List.

17. Hold down the SET switch. If the vehicle did not decelerate, the repair is not complete. Check for TSBs that
pertain to speed control problem and then, if necessary, return to Symptom List.

18. Ensure vehicle speed is greater than 35 mph and release the SET Switch. If vehicle did not adjust and set a
new vehicle speed, the repair is not complete. Check for TSBs that pertain to speed control problem and then, if
necessary, return to Symptom List.

19. Depress and release the CANCEL switch. If the speed control did not disengage, the repair is not complete.
Check for TSBs that pertain to speed control problem and then, if necessary, return to Symptom List.

20. Bring the vehicle speed back up above 35 mph and engage speed control.

21. Depress the OFF switch to turn OFF, (Cruise light will be off). If the speed control did not disengage, the repair
is not complete. Check for TSBs that pertain to speed control problem and then, if necessary, return to Symptom
List.

22. If the vehicle successfully passed all of the previous tests, the speed control system is now functioning as
designed. The repair is now complete.

23. NOTE: OVERSHOOT/UNDERSHOOT FOLLOWING SPEED CONTROL SET.

24. If the vehicle operator repeatedly presses and releases the SET button with their foot off of the accelerator
(referred to as

25. It may also decelerate to less than the desired set speed, before finally achieving the desired set speed.

26. The Speed Control System has an adaptive strategy that compensates for vehicle-to-vehicle variations in speed
control cable lengths.

27. When the speed control is set with the vehicles operators foot off of the accelerator pedal, the speed control
thinks there is excessive speed control cable slack and adapts accordingly.

28. If the

9

lift foot sets

9

are continually used, a speed control overshoot/undershoot condition will develop.

29. To

9

unlearn

9

the overshoot/undershoot condition, the vehicle operator has to press and release the set button

while maintaining the desired set speed using the accelerator pedal (not decelerating or accelerating).

30. Then turning the cruise control switch to the OFF position (or press the CANCEL button if equipped) after wait-
ing 10 seconds.

31. This procedure must be performed approximately 10-15 times to completely unlearn the overshoot/undershoot
condition.

Did the Speed Control pass the above test?

Yes

>> Repair is not complete, refer to appropriate symptom.

No

>> Repair is complete.

and Air bag modules. In addition, if vehicle is equipped with a Sentry Key Immobilizer Module (SKIM), Secret Key
data must be updated to enable start.

10. For ABS and Air Bag systems: Enter correct VIN and Mileage in ECM. Erase codes in ABS and Air Bag mod-
ules.

11. For SKIM theft alarm: Connect scan tool to data link connector to Theft Alarm, SKIM, Misc. and place SKIM in
secured access mode by using appropriate PIN code for this vehicle. Select Update the Secret Key data. Data will
be transferred from SKIM to PCM.

12. If a Comprehensive Component DTC was repaired, perform steps 10-13. If a Major OBDII Monitor DTC was
repaired skip those steps and continue verification.

13. After the ignition has been off for at least 10 seconds, restart the vehicle and run 2 minutes.

14. If there are no new DTC’s, the repair was successful and is now complete. Erase DTC’s and disconnect the
