DTC C0500-12: Left Front Wheel Speed Sensor Circuit Short to Battery [09/2023 - 12/2023]: Description
WARNING: This page is about a different car, the 2024 Lexus TX 550h+ and 2024 Lexus TX 500h. However, it is still accessible from the selected car via links, so may be relevant.
The speed sensor detects wheel speed and sends the appropriate signals to the No. 2 skid control ECU (brake actuator assembly). These signals are used for brake control.
Speed sensor rotors have rows of alternating N and S magnetic poles, and their magnetic fields change when the rotors turn.
Each speed sensor detects that magnetic change and sends a pulse signal to the No. 2 skid control ECU (brake actuator assembly).
