BYD ATTO 3 (e-Platform 3.0) C050600 Right Front Wheel Speed Sensor Open Circuit

C050600 indicates an open circuit involving the right front wheel speed sensor circuit. The fault affects the ABS and wheel-speed monitoring system, which uses individual wheel-speed signals to support ABS, traction control, electronic stability control, and related vehicle functions. The BYD ATTO 3 uses BYD’s e-Platform 3.0 architecture, with this generation introduced from 2022 and continuing onward.

Symptoms

• ABS warning light illuminated
• Traction control or stability control warning
• Wheel-speed-related fault stored in the vehicle
• ABS or stability control functions may be disabled
• Regenerative braking behaviour may be affected
• Warning messages displayed on the instrument cluster
• Right front wheel-speed data may be missing or implausible
• Fault may occur intermittently or remain continuously active

Possible Causes

• Open circuit in the right front wheel speed sensor wiring
• Failed or damaged right front wheel speed sensor
• Loose, damaged, or corroded electrical connector
• Broken wiring near the wheel hub or suspension
• Poor connector terminal contact
• Damaged sensor mounting or harness
• Water or road contamination entering the connector
• Incorrect sensor installation after brake or suspension work
• Fault within the ABS/ESC control system

Diagnosis

Diagnosis should begin by confirming C050600 with a suitable diagnostic system and checking live wheel-speed data to determine whether the right front signal is missing or implausible. The sensor connector, wiring, circuit continuity, electrical supply or signal characteristics, and ABS/ESC control-system inputs should then be assessed against manufacturer specifications. The sensor and harness should also be inspected around the wheel hub and suspension for physical damage, contamination, or poor routing. Many independent workshops throughout New Zealand rely on OEM diagnostic information to verify faults before replacing components.

Accurately diagnosing this fault often requires manufacturer testing procedures, wiring diagrams, connector pinouts, specifications, and system calibration information. Access to the factory service manual significantly reduces diagnostic time and helps prevent unnecessary parts replacement.
