Solstice L4-2.0L Turbo (2008)
For step-by-step programming instructions, please refer to SI and the Techline Information System (TIS) terminal.
Review the information below to ensure proper programming protocol.
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 Multiple Diagnostic Interface (MDI) or Tech2(R) and the TIS terminal are equipped with the latest software before
performing (SPS).
^
Due to the time requirements of programming a controller, it is recommended that an external power source be used to maintain system voltage.
Stable battery voltage is critical during programming. Any fluctuation, spiking, over voltage or loss of voltage will interrupt programming. To
ensure trouble-free programming, GM recommends using one of the following external power sources:
-
A Midtronic PCS charger.
-
A fully charged 12V jumper or booster pack disconnected from the AC voltage supply.
-
Some vehicles may require the use of a CANDI module for programming.
-
Review the appropriate service information for these procedures.
-
DTCs may set during programming. Clear DTCs after programming is complete.
-
Clearing powertrain DTCs will set the Inspection/Maintenance (I/M) system status indicators to NO.
Ensure the following conditions are met before programming a control module:
^
FlexFuel (E85) Vehicles
-
The fuel composition learn function is inactive. Programming with the fuel composition learn active will result in fuel trim DTCs.
-
If necessary, drive the vehicle until the scan tool indicates that the fuel composition learn is inactive.
^
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 fully charged before programming the control module.
-
Turn OFF or disable any system that may put a load on the vehicle's battery, such as the following components:
-
Twilight sentinel
-
Interior lights
-
Daytime running lights (DRL) - Applying the parking brake, on most vehicles, disables the DRL system
-
Heating, ventilation, and air conditioning (HVAC) systems
-
Engine cooling fans, radio, etc.
^
The ignition switch must be in the proper position. SPS 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.
^
Make certain all tool connections are secure, including the following components and circuits:
-
The RS-232 communication cable port.
-
The connection at the data link connector (DLC)
-
The voltage supply circuits
^
DO NOT disturb the tool harnesses while programming. If an interruption occurs during the programming procedure, programming failure or control
