GM DPS – Development Programming System for ECU Flashing & Validation 4.54.1

thank you

hi, how can i activate remote start on bcm on 2022 chevy traverse is not showing in the system they told me only dealer can do that. is anyone that can help me here? thank you

Thanks

For a 2022 Chevy Traverse, you are likely dealing with a vehicle that requires a VCI (Vehicle Configuration Index) code to enable options that were not factory installed.

The reason it is "not showing in the system" is that the BCM configuration is locked based on the VIN's build data. The "dealer only" method refers to using SPS2, where you purchase the upgrade from GM, they generate a new VCI code for your VIN, and then SPS2 downloads the modified configuration to the car.

To do this with GM DPS, it is much more complex and risky on a 2022 model:

• You would need to read the BCM configuration (usually a specific DID).
• You need to know exactly which byte or bit controls the Remote Start RPO.
• Even if you change the bit, 2022+ modules often have checksums or digital signatures on the configuration data. If you write a modified string via DPS without the correct signature, the BCM may reject it or go into a security lockout mode.

Unless you have the specific byte mapping for that BCM and a way to calculate the checksum/signature, the SPS2 method with a purchased VCI is indeed the safest route for a 2022 vehicle.

thank you, for explanation, i have another chevy same model 2019 and it has remote start i could use to backup or so, or swap?
what you mean with SPS2 method with a purchased VCI is inneed? can i buy a program sesion online from GM that i can program my car?

Regarding the 2019 model: No, you cannot simply copy the configuration.
The configuration data in the BCM is mathematically tied to the specific VIN of the car. If you copy the string from the 2019 and write it to the 2022, the module will likely reject it due to a checksum/signature mismatch, or it will accept it but set a "Configuration Mismatch" DTC because the VINs do not match. Furthermore, the 2022 Traverse moved to the newer Global B (VIP) electrical architecture, which has much tighter security than the 2019 model.

Regarding your question about SPS2 and VCI:

• SPS2 is the official GM programming software (accessed via Techline Connect).
• VCI (Vehicle Configuration Index) is not a piece of hardware you buy. It is a server-side override code.

When you use SPS2 normally, it downloads the "As-Built" data from GM's server. Since your car didn't come with remote start, the server sends a file that says "Remote Start = Disabled."

To change this officially, the process is:

1. You purchase the official GM Accessory Remote Start kit (which usually includes new key fobs and an authorization code).
2. You purchase a programming subscription at ACDelco TDS (approx. $45 USD for 1 VIN).
3. You contact GM Techline support and provide the authorization code from the kit. They update the server for your VIN (this is the "VCI" step).
4. You run SPS2, and now the server downloads the new file that says "Remote Start = Enabled."

Without that official VCI update on the server, SPS2 will just keep flashing the original factory settings to the car.

You're welcome. Good luck with the Traverse! If you decide to go the official route with SPS2 and need help navigating the ACDelco TDS site, feel free to ask.
