Chevrolet Trax: Chassis control module programming and setup

NOTE:

• DO NOT program a control module unless directed to by a service procedure or a service bulletin. If the control module is not properly configured with the correct calibration software, the control module will not control all of the vehicle features properly.
• Ensure the programming tool is equipped with the latest software and is securely connected to the data link connector. If there is an interruption during programming, programming failure or control module damage may occur.
• Stable battery voltage is critical during programming. Any fluctuation, spiking, over voltage or loss of voltage will interrupt programming. When required install the EL-49642 SPS Programming Support Tool to maintain system voltage. If not available, connect a fully charged 12 V jumper or booster pack disconnected from the AC voltage supply. DO NOT connect a battery charger.
• Turn OFF or disable systems that may put a load on the vehicles battery such as; interior lights, exterior lights (including daytime running lights), HVAC, radio, etc.
• During the programming procedure, follow the SPS prompts for the correct ignition switch position.
• Clear DTCs after programming is complete. Clearing powertrain DTCs will set the Inspection/Maintenance (I/M) system status indicators to NO.

Unsuccessful Programming Recovery

In the event of an interrupted or unsuccessful programming event, perform the following steps:

1. Ignition ON. Ensure the control module, DLC and programming tool connections are secure and the SPS software is up to date.
2.  Verify the control module can be reprogrammed.

• If the control module cannot be reprogrammed

1. Ignition OFF for one minute, ignition ON.
2. Verify the control module can be reprogrammed.

• If the control module cannot be reprogrammed, replace the control module.
• If the control module can be reprogrammed.

3. All OK.

• If the control module can be reprogrammed

3. All OK.

Repair Instructions

Perform the Diagnostic Repair Verification after completing the repair.

COMMUNICATION INTERFACE MODULE PROGRAMMING AND SETUP

NOTE:

• DO NOT program a control module unless directed to by a service procedure or a service bulletin. If the control module is not properly configured with the correct calibration software, the control module will not control all of the vehicle features properly.
• Ensure the programming tool is equipped with the latest software and is securely connected to the data link connector. If there is an interruption during programming, programming failure or control module damage may occur.

• During the programming procedure, follow the SPS prompts for the correct ignition switch position.
• Clear DTCs after programming is complete. Clearing powertrain DTCs will set the Inspection/Maintenance (I/M) system status indicators to NO.

Diagnostic Aids

• It is critical to use the service replacement Communication Interface Module only in the vehicle for which it was ordered.
• Failure to perform the following procedures will result in a red LED, DTC(s) being set, and limited or incomplete OnStar services.
• An OnStar button press to the OnStar call center is not required to complete the procedure.

  It may take up to 24 hours for OnStar service to become fully activated after performing the procedures.

  Perform the following procedure only once. Repeat attempts of the procedure may result in a delay of the activation process.

• To fully activate an OnStar module, both the setup and activation request procedures must be completed on all vehicles with and without an active OnStar subscription to insure the unit has been setup properly for the vehicle it has been installed into and also to update the OnStar with the correct unit information.
• To initialize the Turn-by-Turn feature, the vehicle must first be driven In open sky condition at speeds greater than 10 mph (16 kph) or more for a minimum of 5 miles (8 km) , and perform at least 2 left and 2 right 90 degree turns coming to complete stops prior to each turn.
• On vehicles up fitted with TTY capabilities, it is necessary to perform a power cycle of the OnStar Interface Module (OTIM), and toggle the TTY mode after completing the Communication Interface Module installation and setup procedures.

CONTROL SOLENOID VALVE AND TRANSMISSION CONTROL MODULE ASSEMBLY PROGRAMMING AND SETUP (6T30/6T40/6T45/6T50)

The following service procedures require either a programming or a setup event be performed for a complete repair. The transmission control module (TCM) is part of the control solenoid valve assembly, and is not serviced separately.

Transmission Control Module (TCM) Replacement

If the TCM is replaced, the following procedures must be performed:

1. TCM Reprogramming
2. The Transmission Adaptive Values Learn. Refer to Transmission Adaptive Values Learn .

TCM Reprogramming

NOTE:

•  Use a scan tool to view and record the Transmission Control Module - End Model Part Number in the original TCM prior to starting the TCM reprogramming procedure.
• In some cases, the TCM and ECM may have to be reprogrammed.

  When a selection for TCM Transmission Control Module - Programming is not available, select SEQ Programming Sequence ECM/TCM (Automatic Transmission Only).

1. If the TCM needs to be reprogrammed. Refer to Service Programming System (SPS).
2. Perform the Transmission Adaptive Values Learn. Refer to Transmission Adaptive Values Learn .

NOTE: After programming, perform the following to avoid future misdiagnosis:

1. Turn the ignition OFF for 30 seconds.
2. Turn the ignition ON with the engine OFF.
3. Use the scan tool in order to retrieve history DTCs from all modules.
4.  Clear all history DTCs.

Setup for Component Replacement

The replacement of some components will require a setup procedure for complete repair.

If any of the following components are replaced, the Transmission Adaptive Values Learn procedure must be performed:

• Transmission replacement
• Any internal transmission repair
• Any speed sensor

Refer to Transmission Adaptive Values Learn
