- The EBCM disables the ABS and may disable the DRP if more than one wheel speed sensor DTC is set.
- The ABS indicator turns ON.
- The brake warning indicator may turn ON.
The actions above are maintained during subsequent ignition cycles until the EBCM completes a power up self-test. This test concludes when the vehicle achieves a speed greater than 13 km/h (8 mph) and the wheel speeds are verified by the EBCM.
