DTC C0210/33 Rear Speed Sensor RH Circuit

DTC C0215/34 Rear Speed Sensor LH Circuit

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

DTC C1274/74 Low Output Signal of Rear Speed Sensor LH (Test Mode DTC)


DESCRIPTION

The speed sensors detect the wheel speeds and send appropriate signals to the skid control ECU. The speed sensor has a magnet behind its detection terminal, and detects changes in magnetic flux density between the peaks and valleys of the magnetic rotor teeth.
The speed sensors detect those magnetic changes and send pulse signals to the skid control ECU. The ECU monitors the wheel speeds through these pulse signals to control the ABS.
DTCs C1273/73 and C1274/74 are deleted when the speed sensor sends a vehicle speed signal or Test Mode ends. DTCs C1273/73 and C1274/74 are output only in Test Mode.
HINT:
When the connectors between the speed sensor and skid control ECU are connected, the following waveform is output.

INSPECTION PROCEDURE

NOTICE:
  1. When replacing the brake actuator assembly, perform zero point calibration (Toyota Fortuner RM000000XHR02TX.html).
  2. Check the speed sensor signal in test mode after replacing parts or clearing DTCs (Toyota Fortuner RM000000XHT070X.html).
1.CHECK HARNESS AND CONNECTOR (MOMENTARY INTERRUPTION)

  1. Using the intelligent tester, check for any momentary interruption in the wire harnesses and connectors corresponding to the DTC (Toyota Fortuner RM000000XHS04KX.html).

2.READ VALUE USING INTELLIGENT TESTER (RR/RL WHEEL SPEED)

  1. Turn the ignition switch off.

  1. Connect the intelligent tester to the DLC3.

  1. Start the engine.

  1. Select the Data List mode on the intelligent tester (Toyota Fortuner RM000000XHW080X.html).

    ABS/VSC/TRC
    Tester Display
    		Measurement Item/Range
    		Normal Condition
    		Diagnostic Note
    RR Wheel Speed
    		Rear wheel RH speed sensor reading / min.: 0 km/h (0 mph), max.: 326 km/h (202 mph)
    		Actual wheel speed
    		Similar to speed indicated on speedometer
    RL Wheel Speed
    		Rear wheel LH speed sensor reading / min.: 0 km/h (0 mph), max.: 326 km/h (202 mph)
    		Actual wheel speed
    		Similar to speed indicated on speedometer

  1. Check that there is no significant difference between the speed value displayed on the intelligent tester and the speed value displayed on the speedometer when driving the vehicle.

    HINT:
    Factors that affect the indicated vehicle speed include tire size, tire inflation, and tire wear. The speed indicated on the speedometer has an allowable margin of error. This can be tested using a speedometer tester (calibrated chassis dynamometer). For details about testing and the margin of error, see the reference chart (Toyota Fortuner RM0000011JB00MX.html).
    OK:
    The speed value displayed on the intelligent tester is almost the same as the actual vehicle speed measured using a speedometer tester (calibrated chassis dynamometer).
