C0506 on Cadillac
Right Front Wheel Speed Sensor / System Circuit (manufacturer-specific)
C0506 on Cadillac vehicles indicates right front wheel speed sensor / system circuit (manufacturer-specific). Au7o has documented this code across 1 Cadillac model — most commonly on Escalade ESV. C0506 is a chassis code whose exact meaning is manufacturer- and platform-specific. On many newer GM applications it is defined as a right front wheel speed sensor circuit (open) fault, while some older or other references list it as a system/communication-related ABS code, so the precise definition should be confirmed with OEM service data for the specific vehicle. In general it points to a fault the ABS/stability module detected in a wheel-speed or system circuit, and ABS/traction/stability functions may be disabled with warning lights on. Base braking is retained. Typical repair costs on Cadillac range from $250 to $2,500, depending on the specific model and root cause.
Common Causes of C0506
- •Faulty right front wheel speed sensor (GM applications)
- •Open or damaged sensor wiring
- •Corroded or loose sensor connector
- •Debris or tone ring damage at the sensor
- •Module communication or serial-data fault (some platforms)
- •Poor ground or connection at the ABS/EBCM
- •Internal ABS module fault

Cadillac Escalade ESV(1 issue)
- Super Cruise and Driver Assistance System Faults from Camera/Radar Module Errors2021-2025
Owners have reported repeated 'Service Driver Assist System,' 'Super Cruise Unavailable,' and related warnings on current-generation Escalade ESV models. Problems are commonly tied to front camera calibration faults, radar sensor communication issues, software bugs, or poor module alignment after windshield work or minor front-end impacts. In some cases adaptive cruise, lane keeping, automatic emergency braking, and Super Cruise become unavailable until repaired.
