The defect
General Motors is recalling certain 2019-2020 Chevrolet 4500HD, 5500HD, and 6500HD Medium Duty trucks. If the vehicle's body control module (BCM) loses communication with the vehicle's electronic brake control module (EBCM), the EBCM software programming may not illuminate the vehicle's ABS malfunction indicator light (MIL). As such, these vehicles fail to comply with Federal Motor Vehicle Safety Standard (FMVSS) Number 105, "Hydraulic and Electric Brake Systems."
The risk
If a driver is unaware that the ABS system is malfunctioning, there may be an increased risk of a crash.
