Speedometer Drops / ABS & Hill Assist On
Diagnosis & fix steps
LOGIC: Vehicle Speed Sensor "A" Malfunction.
ACTION: Scan the VDC/ABS control unit to isolate which individual wheel speed sensor is dropping signal. Trace wheel speed sensor harnesses along lower control arms for gravel strikes or conductor breaks.
Red Seal field insights
Hub Bearing Tone Rings: Integrated magnetic tone rings in the rear wheel wheel bearings corrode from road brine, dropping pulses and killing speedometer and cruise control logic.
