VEHICLE STABILITY CONTROL SYSTEM, Diagnostic DTC:C0210/33, C0215/34, C1273/73, C1274/74, C1332/38, C1333/39

DTC Code DTC Name
C0210/33 Rear Speed Sensor RH Circuit
C0215/34 Rear Speed Sensor LH Circuit
C1273/73 Low Output Signal of Rear Speed Sensor RH (Test Mode DTC)
C1274/74 Low Output Signal of Rear Speed Sensor LH (Test Mode DTC)
C1332/38 Right Rear Speed Sensor Circuit
C1333/39 Left Rear Speed Sensor Circuit

DESCRIPTION

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.

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.

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.

  4. READ VALUE ON INTELLIGENT TESTER (REAR SPEED SENSOR)


    1. Turn the engine switch off.

    2. Connect the intelligent tester to the DLC3.

    3. Start the engine.

    4. Select the Data List mode on the intelligent tester Click here.

      ABS/VSC/TRC
      Tester Display Measurement Item/Range Normal Condition Diagnostic Note
      RR Wheel Speed RR wheel speed sensor reading / min.: 0 km/h (0 mph), max.: 326.4 km/h (202 mph) Actual wheel speed Similar speed as indicated on speedometer
      RL Wheel Speed RL wheel speed sensor reading / min.: 0 km/h (0 mph), max.: 326.4 km/h (202 mph) Actual wheel speed Similar speed as indicated on speedometer

    5. Check that there is no difference between the speed value output from the speed sensor displayed on the intelligent tester and the speed value displayed on the speedometer when driving the vehicle.

      Tech Tips

      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 Click here.

      OK
      The speed value output from the speed sensor displayed on the intelligent tester is the same as the actual vehicle speed measured using a speedometer tester (calibrated chassis dynamometer).
