DTC C1415: Rear Speed Sensor RH Output Malfunction; DTC C1416: Rear Speed Sensor LH Output Malfunction [12/2017 - 09/2018]: Description
The speed sensor detects wheel speed and sends the appropriate signals to the 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 skid control ECU (brake actuator assembly).
HINT:
When the connectors between the speed sensor and skid control ECU (brake actuator assembly) are connected, the following waveform is output.
