REPAIR INSTRUCTIONS

SERVICE PROGRAMMING SYSTEM (SPS)

For step by step programming instructions, please refer to the techline information system (TIS) terminal.

Review the information below to ensure proper programming protocol.

Ensure the following conditions are met before programming a control module:

z

Vehicle system voltage

{

There is not a charging system concern. All charging system concerns must be repaired before
programming a control module.

{

Battery voltage is greater than 12 volts but less than 16 volts. The battery must be charged before
programming the control module if the battery voltage is low.

{

A battery charger is NOT connected to the vehicle's battery. Incorrect system voltage or voltage
fluctuations from a battery charger, may cause programming failure or control module damage.

{

Turn OFF or disable any system that may put a load on the vehicle's battery, such as the following
components:

z

Twilight sentinel

z

Interior lights

z

Daytime running lights (DRL) - Applying the parking brake, on most vehicles, disables the
DRL system. Refer to the Owner's manual.

z

Heating, ventilation, and air conditioning (HVAC) systems

z

Engine cooling fans, radio, etc.

z

The ignition switch must be in the proper position. The Tech 2 prompts you to turn ON the ignition, with
the engine OFF. DO NOT change the position of the ignition switch during the programming procedure,
unless instructed to do so.

z

Make certain all tool connections are secure, including the following components and circuits:

IMPORTANT: DO NOT program a control module unless you are directed by a service

procedure or you are directed by a General Motors Corporation service
bulletin. Programming a control module at any other time will not permanently
correct a customer's concern.
It is essential that the Tech 2 and the TIS terminal are both equipped with the
latest software before performing service programming system (SPS).
Some modules will require additional programming/setup events performed
before or after programming.
Review the appropriate service information for these procedures.

DO NOT disturb the tool harnesses while programming. If an interruption occurs during the
programming procedure, programming failure or control module damage may occur.

z

DO NOT turn OFF the ignition if the programming procedure is interrupted or unsuccessful. Ensure that
all control module and DLC connections are secure and the TIS terminal operating software is up to date.
Attempt to reprogram the control module. If the control module cannot be programmed, replace the
control module.
