| 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 brake 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 field change and sends a pulse signal to the skid control ECU.
DTCs C1273/73 and C1274/74 are cleared when the speed sensor sends a vehicle speed signal or Test Mode ends. DTCs C1273/73 and C1274/74 are stored only in Test Mode.
| DTC Code | DTC Detection Condition | Trouble Area |
|---|---|---|
| C0210/33 C0215/34 |
When any of the following is detected:
|
|
| C1332/38 C1333/39 |
Abnormality in the resistance value of a speed sensor is detected. |
|
| C1273/73 C1274/74 |
Stored during Test Mode. |

Tech Tips
DTCs C0210/33, C1273/73 and C1332/38 are for the rear speed sensor RH.
DTCs C0215/34, C1274/74 and C1333/39 are for the rear speed sensor LH.

INSPECTION PROCEDURE
Note
When replacing the skid control ECU (brake actuator assembly), perform the engine variant learning Click here.
PROCEDURE
CHECK HARNESS AND CONNECTOR (MOMENTARY INTERRUPTION)
Using the intelligent tester, check for any momentary interruption in the wire harness and connector corresponding to the DTC Click here.
| Tester Display | Measurement Item/Range | Normal Condition | Diagnostic Note |
|---|---|---|---|
| RR Speed Open | Rear speed sensor RH open detection/ Error or Normal | Normal | - |
| RL Speed Open | Rear speed sensor LH open detection/ Error or Normal | Normal | - |
| Result | Proceed to |
|---|---|
| There are momentary interruptions. | A |
| There are no momentary interruptions. | B |
| There is a constant open circuit. | C |
Tech Tips
Perform the above inspection before removing the sensor and connector.

READ VALUE USING INTELLIGENT TESTER (RR/RL WHEEL SPEED)
Turn the ignition switch off.
Connect the intelligent tester to the DLC3.
Start the engine.
Select the Data List mode on the intelligent tester Click here.
| Tester Display | Measurement Item/Range | Normal Condition | Diagnostic Note |
|---|---|---|---|
| RR Wheel Speed | Rear speed sensor RH reading/ min.: 0 km/h (0 mph), max.: 326 km/h (202 mph) | Actual wheel speed | Driving at constant speed: No large fluctuations |
| RL Wheel Speed | Rear speed sensor LH reading/ min.: 0 km/h (0 mph), max.: 326 km/h (202 mph) | Actual wheel speed | Driving at constant speed: No large fluctuations |
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.
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.
