If You’re Seeing GMC Code P2108 in Colleyville, TX – Here’s What You Need to Know

If you’re a repair shop, used car dealer, or vehicle owner in the Colleyville TX area and you’re seeing the diagnostic trouble code P2108 on a GMC vehicle, it’s critical to understand what this code means—and how it can impact your vehicle’s safety systems, especially the airbags.

What Does GMC Code P2108 Mean?

DTC P2108 for GMC vehicles refers to a fault in the Driver Knee Bolster Squib Control Circuit—specifically, a short to battery condition. In simpler terms, this indicates an electrical issue where the airbag squib (a small explosive component that triggers deployment) is receiving unintended voltage. This can seriously affect airbag performance and safety during a collision.

Common Causes of P2108 in GMC Vehicles

Damaged wiring or connectors in the knee airbag circuit
Frayed or exposed wires causing a short circuit to battery voltage
Faulty airbag squib in the driver’s knee bolster
Malfunctioning SRS (Supplemental Restraint System) control module
Improper module programming following a collision repair

This code is particularly common among salvage or rebuilt title vehicles, making it highly relevant for used car dealerships and body shops.

Symptoms Associated with the P2108 Code

Persistent airbag warning light in the instrument cluster
Stored SRS fault code during diagnostic scans
Increased injury risk due to non-deploying airbags in a crash
Failure of state inspection due to unresolved airbag warning

If prepping vehicles for resale, unresolved airbag faults like P2108 can negatively affect CarFax and AutoCheck reports, reducing vehicle value.
