DTC C1273/73 Low Output Signal of Rear Speed Sensor RH (Test Mode DTC)

DESCRIPTION

DTC Detecting Condition:

The speed sensor detects wheel speed and sends the appropriate signals to the skid control ECU. These signals are used for the ABS control system. The speed sensor detects changes in the magnetic field generated by the magnetic rotor which has the north and south poles evenly located in circumferential direction and generates the vehicle speed pulse. The skid control ECU detects each wheel speed based on the vehicle speed pulse.

DTCs C1273/73 and C1274/74 can be deleted when the speed sensor sends a vehicle speed signal or the test mode ends. DTCs C1273/73 and C1274/74 are output only in the test mode.

HINT:
- DTC C0210/33 is for the right rear speed sensor.
- DTC C0205/32 is for the left rear speed sensor.
