A VCI number does not allow you to access calibrations that are designated “Not
Selectable.” It is important to ensure you have the correct VCI number to access the
calibrations before reprogramming.
Selecting the Right Calibration
When reprogramming a vehicle, selecting the right calibration is critical. You will only see
calibrations that are valid for the VIN entered. Be sure to check the history of each
calibration. The history lists an explanation of the calibration file, telling what the calibration
is for and whether it supersedes any other calibrations. It is helpful to read the latest
bulletins to stay up to date on why certain calibrations have been released. Related bulletin
numbers are sometimes listed along with the calibration files.
Based on the calibration history and bulletins, select the appropriate calibration file. For
many vehicles equipped with VCMs, you’ll also need to complete the multiple tab
selections. Each tab is for a distinct calibration file contained in the VCM. An unchecked
box on a system tab indicates that a necessary selection has not been made.
If you need a VCI number, contact the ACDelco Aftermarket Support Center 888.212.8959.
Once you have the VCI number, it must be entered in the entry screen when requested by
the SPS.
The two main SPS methods are:
• Remote Programming
• Pass-Thru Programming
Regardless of the vehicle involved, the general three-part process for SPS programming is
as follows:
1.
Check the vehicle’s control module to determine which, if any, calibration file is
currently stored.
2. Determine if an update is required.
3.
Transfer the selected data to the vehicle’s control module.
NOTICE:
Prior to performing SPS, it is important to heed the following precautions:
• Using an outdated version could damage vehicle modules. The Tech2 and the
computer must have the latest software.
• Make sure the vehicle battery is fully charged. Battery voltage for SPS should be
between 12 and 14 volts. However, a battery charger must not be connected to the
vehicle when using the Tech2.
• Make sure the cable connections are secure. A disconnected cable could cause
controller failure.
• If you use a laptop computer for pass-thru programming, ensure that the power
supply is properly connected. If powered by AC and the power cord becomes
disconnected, it could interrupt programming and cause damage to the control
module. If the laptop is operating from its internal power source (batteries), then
make sure it is adequately charged to complete the SPS process.
