ABS W/EBD System

DTC 34 LEFT REAR WHEEL SPEED SENSOR SIGNAL MALFUNCTION

CIRCUIT DESCRIPTION

DTC Detecting Conditions:

The speed sensor detects the wheel speeds and sends the appropriate signals to the skid control ECU.

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. The ECU monitors the wheel speeds according to the speed signals to control the ABS control system.

HINT:
DTC C0200/31 relates to the right front speed sensor.
DTC C0205/32 relates to the left front speed sensor.
DTC C0210/33 relates to the right rear speed sensor.
DTC C0215/34 relates to the left rear speed sensor.
