What Does DTC P1603 Mean?

The DTC P1603 for Cadillac vehicles specifically refers to an issue with the Anti-lock Braking System (ABS), particularly focusing on the wheel speed sensor or the ABS sensor rotor system. This code indicates that one or more of the wheel speed signals from the vehicle’s four wheels exhibit abnormal acceleration, deviating from the preset specifications. The malfunction in signal wave patterns from the ABS wheel speed sensors is typically at the root of this issue. For precise details, check your vehicle’s specifics using our VIN Decoder.
