Action Taken When the DTC Sets

WARNING: This page is about a different car, the 2002 Chevrolet Malibu. However, it is still accessible from the selected car via links, so may be relevant.

The EBCM disables the ABS for the duration of the ignition cycle.
The ABS indicator turns ON.
The DRP does not function optimally.
For DTC C1265 or C1267, the red Brake warning indicator turns ON. When both DTCs C1265 and C1267 are set or a wheel speed sensor DTC for the other wheel on the same axle is also set, the EBCM disables the DRP for the duration of the ignition cycle.
