Owners of the 2023 Chevrolet Colorado and GMC Canyon who have a “Service Driver Assist” error message may not actually have anything wrong.
A Technical Service Bulletin (TSB) released by General Motors, titled 24-NA-014 – Information on a False DTV B17E2 Setting,” indicates that software issues may be the cause of the error message- not that anything is wrong or needs to be repaired.
This TSB applies only to the 2023 Chevrolet Colorado and 2023 GMC Canyon models and isn’t related to an issue that stopped the sale of 2024 Colorado and Canyon models.
TSB 24-NA-015 – Condition / Cause / Correction
The Technical Service Bulletin, a document written for dealership technicians, goes over the following details about the issue.
Condition: Some customers may comment on a Service Driver Assist message illuminated in the DIC. Technician may find DTC B17E2 set
Cause: The cause of the condition may be a software anomaly setting the false code.
Correction: DO NOT diagnose, this is a false code setting. The Chevrolet Colorado and GMC Canyon do not use a headrest position that sets the false code. A software update will be released to correct it.
It’s unsure if the eventual software update will be delivered over the air (OTA) or via a trip to your dealer. However, it’s reassuring to know there’s nothing really wrong or needs repair. The experts here at GM-Trucks.com will keep you updated if/when the software fix is released and how owners can go about getting it applied to their Colorado and/or Canyon.
