Powertrain Verification Test VER-4

1. Inspect vehicle to ensure all engine and S/C system components are properly installed and connected. Reassemble and reconnect components as necessary.
2. Turn ignition off. Install DRBIII® to DLC. Using DRBIII®, erase DTCs.
3. If PCM was not replaced, go to step  7. If PCM was replaced, go to next step.
4. If PCM was replaced, the correct VIN and mileage must be programmed or a DTC will set in ABS and air bag modules. In addition, if vehicle is equipped with SKIM, secret key data must be updated to enable engine start.
5. For ABS and air bag system, enter correct VIN and mileage in PCM. Erase DTCs in ABS and air bag modules.
6. For SKIM theft alarm, using DRBIII®, select THEFT ALARM, SKIM, MISC and place SKIM in secured access mode by entering the appropriate PIN for this vehicle. Select UPDATE SECRET KEY DATA. Data will be transferred from SKIM to PCM.
7. Turn S/C on. CRUISE indicator will illuminate (if equipped).
8. Road test vehicle at a speed more than 35 MPH. Depress and release SET button. The S/C should engage and hold the selected speed.
9. Depress and hold RESUME/ACCEL switch. The vehicle speed should increase by at least 2 MPH.
10. Press and hold COAST switch. Vehicle speed should decrease.
11. Using caution, depress and release brake pedal. S/C should disengage.
12. Bring vehicle speed back up to 35 MPH.
13. Depress the RESUME/ACCEL switch. The S/C should resume the previously set speed.
14. Hold down the SET switch. Vehicle speed should decrease.
15. Ensure vehicle speed is more than 35 MPH and release the SET switch. The vehicle should adjust and set a new vehicle speed.
16. Depress and release CANCEL switch. The S/C should disengage.
17. Bring vehicle speed is back up to more than 35 MPH. Engage S/C.
18. Depress ON/OFF switch off. CRUISE light should go off (if equipped) and S/C should disengage.
19. Note overshoot/undershoot following S/C set.
20. If the vehicle operator repeatedly depresses and releases the SET button with their foot off of the accelerator (lift foot set), the vehicle may accelerate and exceed the desired set speed by up to 5 MPH.
21. Vehicle may also decelerate to less than desired set speed, before finally achieving the desired set speed.
22. The S/C system has an adaptive strategy that compensates for vehicle-to-vehicle variations in S/C cable lengths.
23. When the S/C is set with the vehicle operator's foot off of the accelerator, the S/C determines that there is excessive S/C cable slack and adapts accordingly.
24. If lift foot sets are continuously used, a S/C overshoot/undershoot condition will develop.
25. To unlearn 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 accelerating or decelerating).
26. Vehicle operator must then turn the S/C ON/OFF switch off or press CANCEL button (if equipped) after waiting 10 seconds.
27. This procedure must be repeated approximately 10-15 times to completely unlearn the overshoot/undershoot condition.

Did the S/C pass the above test? If yes, repair is complete. If no, repair is not complete. Check for related TSBs and refer to appropriate diagnostic procedure.
