Toyota Fortuner. Dtc C0210/33 Right Rear Wheel Speed Sensor Signal Malfunction

Refer to DTCs C0200/31, C0205/32, C1235/35 and C1236/36.
DTCs C1273/73, C1274/74, C1277/77 and C1278/78 can be deleted when the speed sensor sends a vehicle speed signal or the test mode ends. DTCs C1273/73, C1274/74, C1277/77 and C1278/78 are output only in the test mode.

2.READ VALUE USING INTELLIGENT TESTER (REAR SPEED SENSOR)

Check the Data List for proper functioning of the rear speed sensor.

Skid control ECU
Item	Measurement Item / Range (Display)	Normal Condition	Diagnostic Note
RR Wheel Speed	Wheel speed sensor (RR) reading / min.: 0 km/h (0 mph), max.: 326 km/h (202 mph)	Actual wheel speed	Speed similar to that of speedometer
RL Wheel Speed	Wheel speed sensor (RL) reading / min.: 0 km/h (0 mph), max.: 326 km/h (202 mph)	Actual wheel speed	Speed similar to that of speedometer

OK:: There is almost no difference between actual wheel speed and displayed speed value.

HINT:

There is a tolerance of +/-10% in the speedometer indication.

Go to step 4

OK

3.INSPECT SPEED SENSOR AND SENSOR ROTOR SERRATIONS

Connect an oscilloscope to terminals 33 (RR+) and 34 (RR-), and 11 (RL+) and 12 (RL-) of the S2 skid control ECU connector.

Drive the vehicle at about 30 km/h (19 mph), and check the signal waveform.
OK:
A waveform is output, as shown in the illustration.
HINT:
1. As vehicle speed (wheel revolution speed) increases, the wavelength shortens and the fluctuation in the output voltage becomes greater.
2. Scratches, looseness or foreign matter on the speed sensor rotor cause noise (errors) in the signal waveform.

Go to step 8

REPLACE BRAKE ACTUATOR ASSEMBLY

4.INSPECT REAR SPEED SENSOR

Disconnect the S19 and S20 sensor connectors.

Measure the resistance of the sensors.

Standard resistance:
LH:
Tester Connection
Specified Condition
1 (RL-) - 2 (RL+)
0.75 to 2.0 kΩ
1 (RL-) - Body ground
10 kΩ or higher
2 (RL+) - Body ground
10 kΩ or higher
RH:
Tester Connection
Specified Condition
1 (RR-) - 2 (RR+)
0.75 to 2.0 kΩ
1 (RR-) - Body ground
10 kΩ or higher
2 (RR+) - Body ground
10 kΩ or higher
HINT:
Check the speed sensor signal after the speed sensor replacement.

REPLACE REAR SPEED SENSOR

OK

5.CHECK WIRE HARNESS (SKID CONTROL ECU - REAR SPEED SENSOR)

Disconnect the S2 ECU connector.

Disconnect the S19 and S20 sensor connectors.

Measure the resistance of the wire harness side connectors.

Standard resistance:
LH:
Tester Connection
Specified Condition
S2-11 (RL+) - S19-2 (RL+)
Below 1 Ω
S2-12 (RL-) - S19-1 (RL-)
Below 1 Ω
S19-2 (RL+) - Body ground
10 kΩ or higher
S19-1 (RL-) - Body ground
10 kΩ or higher
RH:
Tester Connection
Specified Condition
S2-33 (RR+) - S20-2 (RR+)
Below 1 Ω
S2-34 (RR-) - S20-1 (RR-)
Below 1 Ω
S20-2 (RR+) - Body ground
10 kΩ or higher
S20-1 (RR-) - Body ground
10 kΩ or higher

REPAIR OR REPLACE HARNESS AND CONNECTOR

OK

6.INSPECT SPEED SENSOR AND SENSOR ROTOR SERRATIONS

Connect an oscilloscope to terminals 33 (RR+) and 34 (RR-), and 11 (RL+) and 12 (RL-) of the S2 skid control ECU connector.

Drive the vehicle at about 30 km/h (19 mph), and check the signal waveform.
OK:
A waveform is output, as shown in the illustration.
HINT:
1. As vehicle speed (wheel revolution speed) increases, the wavelength shortens and the fluctuation in the output voltage becomes greater.
2. Scratches, looseness or foreign matter on the speed sensor rotor cause noise (errors) in the signal waveform.

Go to step 8

OK

7.CHECK IF DTC OUTPUT RECURS

Clear the DTCs.

Drive the vehicle at approximately 30 km/h (19 mph) or more for 60 seconds or more.

Check for DTCs.

8.INSPECT REAR SPEED SENSOR (INSTALLATION)

Check the speed sensor installation (Toyota Fortuner RM0000010JQ003X.html).
OK:
The installation bolt is tightened properly.
There is no clearance between the sensor and rear axle housing.
HINT:
Check the speed sensor signal after the speed sensor replacement.

SECURELY REINSTALL REAR SPEED SENSOR

OK

9.INSPECT REAR SPEED SENSOR (TIP)

Remove the rear speed sensor.

Check the sensor tip.
OK:
No scratches or foreign matter on sensor tip.
HINT:
1. If the sensor is contaminated with oil or other foreign material, clean the sensor.
2. If there is iron powder sticking to the rotor, this will result in a malfunction, so confirm that the rotor is not contaminated with foreign material before replacing the sensor.
3. Check the speed sensor signal after cleaning or replacing the speed sensor.
NOTICE:
Do not replace the speed sensor if no damage to the speed sensor tip is found.

CLEAN OR REPLACE SPEED SENSOR

OK

10.INSPECT SPEED SENSOR ROTOR

Remove the rear axle shaft with backing plate.

Check the sensor rotor serrations.
OK:
No scratches, missing teeth or foreign matter on sensor rotor.
HINT:
1. If foreign matter is attached, remove it and check the output waveform after reassembly.
2. Check the speed sensor signal after cleaning or replacing the speed sensor rotor.

CLEAN OR REPLACE SPEED SENSOR ROTOR

OK

11.CHECK IF DTC OUTPUT RECURS

Clear the DTCs.

Drive the vehicle at approximately 30 km/h (19 mph) or more for 60 seconds or more.

Check for DTCs.
