C0215
BRAKE CONTROL: VEHICLE STABILITY CONTROL SYSTEM: C0210/33: Rear Speed Sensor RH Circuit
DTC C0210/33 - Rear Speed Sensor RH Circuit
DTC C0215/34 - Rear Speed Sensor LH Circuit
DTC C1238/38 - Foreign Object is Attached on Tip of Rear Speed Sensor RH
DTC C1239/39 - Foreign Object is Attached on Tip of Rear Speed Sensor LH
DESCRIPTION
The speed sensor detects wheel speed and sends the appropriate signals to the ECU. These signals are used to control the ABS, BA, TRAC, A-TRAC, VSC, AUTO LSD, downhill assist and hill-start assist control systems. This speed sensor contains a sensor IC, which consists of 2 MREs (Magnetic Resistance Element). The speed sensor rotor, which consists of 48 sets of N and S poles that are arranged in a circle, is integrated with the inner race of the hub bearing.
To detect the rotation direction, the output waves are used to determine the relationship of the pulses that are generated by the 2 MREs. Upon receiving this signal, the sensor IC outputs a signal indicating forward or reverse rotation to the ECU.
HINT:
- DTC C0210/33 and C1238/38 are for the rear speed sensor RH.
- DTC C0215/34 and C1239/39 are for the rear speed sensor LH.

INSPECTION PROCEDURE
NOTE: When replacing the master cylinder solenoid, perform zero point calibration Programming and Relearning.
PROCEDURE
1. READ VALUE USING TECHSTREAM (MOMENTARY INTERRUPTION OF REAR SPEED SENSOR)
(a) Connect the Techstream to the DLC3.
(b) Turn the ignition switch to ON and turn the Techstream main switch ON.
(c) Select "Data List" mode on the Techstream.
ABS/VSC/TRAC
(d) Check for any momentary interruption in the wire harness and connector corresponding to a DTC Check for Intermittent Problems.
OK:
There are no momentary interruptions.
HINT: Perform the above inspection before removing the sensor and connector.
NG -- REPAIR OR REPLACE HARNESS OR CONNECTOR (SPEED SENSOR CIRCUIT)
OK -- Continue to next step.
2. READ VALUE USING TECHSTREAM (REAR SPEED SENSOR)
ABS/VSC/TRAC
(a) Check that there is no difference between the speed value displayed on the Techstream and the speed value displayed on the speedometer when driving the vehicle.
OK:
The speed value displayed on the Techstream is the same as the actual vehicle speed.
NG -- INSPECT REAR SPEED SENSOR INSTALLATION
OK -- Continue to next step.
3. PERFORM TEST MODE (SIGNAL CHECK)
(a) Check if test mode (signal check) DTCs are detected.
Result:
B -- RECONFIRM DTC
A -- Continue to next step.
4. INSPECT REAR SPEED SENSOR INSTALLATION
(a) Check the speed sensor installation.
OK:
The installation nut is tightened properly.
There is no clearance between the sensor and the rear axle.
Torque: 8.3 Nm (85 kgf-cm, 73 in-lbf)
NOTE: Check the speed sensor signal after replacement Test Mode Procedure.
NG -- INSTALL REAR SPEED SENSOR CORRECTLY
OK -- Continue to next step.
5. INSPECT SPEED SENSOR TIP
(a) Remove the rear speed sensor Removal.
(b) Check the sensor tip.
OK:
No scratches or foreign matter on the sensor tip.
NOTE: Check the speed sensor signal after cleaning/replacement Test Mode Procedure.
NG -- CLEAN OR REPLACE REAR SPEED SENSOR
OK -- Continue to next step.
6. INSPECT REAR SPEED SENSOR
(a) Install the rear speed sensor.
(b) Turn the ignition switch off.
(c) Disconnect the rear speed sensor connector.
(d) Measure the resistance according to the value(s) in the table below.
Standard resistance:
for RH
for LH
NG -- REPLACE REAR SPEED SENSOR
OK -- Continue to next step.
7. INSPECT SKID CONTROL SENSOR WIRE
(a) Disconnect the skid control sensor wire.
(b) Measure the resistance according to the value(s) in the table below.
Standard resistance:
for RH
for LH
NOTE: Check the speed sensor signal after replacement Test Mode Procedure.
NG -- REPLACE SKID CONTROL SENSOR WIRE
OK -- Continue to next step.
8. CHECK HARNESS AND CONNECTOR (SKID CONTROL ECU - REAR SPEED SENSOR)
(a) Disconnect the skid control ECU connector.
(b) Measure the resistance according to the value(s) in the table below.
Standard resistance:
for RH
for LH
NG -- REPAIR OR REPLACE HARNESS OR CONNECTOR
OK -- Continue to next step.
9. INSPECT MASTER CYLINDER SOLENOID
(a) Reconnect the skid control ECU connector.
(b) Turn the ignition switch to ON.
(c) Measure the voltage according to the value(s) in the table below.
Standard voltage:
for RH
for LH
NG -- REPLACE MASTER CYLINDER SOLENOID
OK -- Continue to next step.
10. RECONFIRM DTC C0200
B -- CHECK FOR INTERMITTENT PROBLEMS
A -- Continue to next step.
11. REPLACE REAR SPEED SENSOR
(a) Replace the rear speed sensor Removal.
NOTE: Check the speed sensor signal after replacement Test Mode Procedure.
NEXT -- Continue to next step.
12. RECONFIRM DTC C0200
B -- END
A -- Continue to next step.
13. INSPECT SPEED SENSOR ROTOR
(a) Remove the rear axle bearing assembly Removal.
(b) Check the sensor rotor.
OK:
No scratches, oil, or foreign matter on the rotor.
NOTE: Check the speed sensor signal after cleaning/replacement Test Mode Procedure.
NG -- CLEAN OR REPLACE REAR AXLE BEARING ASSEMBLY (SPEED SENSOR ROTOR)
OK -- REPLACE MASTER CYLINDER SOLENOID
