WIRING DIAGRAM
Refer to DTCs C1403 and C1404 Click here.
INSPECTION PROCEDURE
Note
When replacing the brake actuator assembly, perform zero point calibration and store system information Click here.
PROCEDURE
CHECK HARNESS AND CONNECTOR (MOMENTARY INTERRUPTION)
Using the GTS, 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 | - |
OK |
---|
Normal (there are no momentary interruptions). |
Tech Tips
Perform the above inspection before removing the sensor and disconnecting the connector.
NG |
OK |
READ VALUE USING GTS (RR/RL WHEEL SPEED)
Turn the engine switch off.
Connect the GTS to the DLC3.
Start the engine.
Turn the GTS on.
Enter the following menus: Chassis / ABS/VSC/TRC / Data List.
Tester Display | Measurement Item/Range | Normal Condition | Diagnostic Note |
---|---|---|---|
RR Wheel Speed | Rear speed sensor RH/ min.: 0 km/h (0 mph), max.: 326 km/h (202 mph) | Actual wheel speed | No large fluctuations when driving at a constant speed. |
RL Wheel Speed | Rear speed sensor LH/ min.: 0 km/h (0 mph), max.: 326 km/h (202 mph) | Actual wheel speed | No large fluctuations when driving at a constant speed. |
Check the speed value output from the speed sensor displayed on the GTS.
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 GTS is similar to the speed indicated on the speedometer. |
Tech Tips
If troubleshooting has been carried out according to the problem symptoms table, refer back to the table and proceed to the next suspected area Click here.
NG |
OK |
RECONFIRM DTC
Clear the DTCs Click here.
Turn the engine switch off.
Start the engine.
Drive the vehicle at a speed of 20 km/h (12 mph) or more for at least 15 seconds.
Check if the same DTC is output Click here.

CHECK REAR SPEED SENSOR INSTALLATION
*a | No clearance |
*b | OK |
*c | NG |
Check the speed sensor installation.
OK |
---|
There is no clearance between the sensor and the rear axle carrier. |
The installation bolt is tightened properly. |
NG |
INSTALL REAR SPEED SENSOR CORRECTLY Click here |
OK |
CHECK REAR SPEED SENSOR TIP
Remove the rear speed sensor Click here.
Check the speed sensor tip.
OK |
---|
No scratches, oil, or foreign matter on the sensor tip. |
Note
If no damage to the speed sensor tip is found during this inspection, do not replace the speed sensor.
Check the speed sensor signal after cleaning or replacement Click here.
NG |
CLEAN OR REPLACE REAR SPEED SENSOR |
OK |
CHECK REAR SPEED SENSOR ROTOR
Remove the rear axle hub (rear speed sensor rotor) Click here.
Check the speed sensor rotor.
OK |
---|
No scratches, oil, or foreign matter on the rotors. |
Note
Check the speed sensor signal after cleaning or replacement Click here.
Tech Tips
The rear speed sensor rotor is incorporated into the rear axle hub and bearing assembly.
If the rear speed sensor rotor needs to be replaced, replace it together with the rear axle hub and bearing assembly.
NG |
CLEAN OR REPLACE REAR SPEED SENSOR ROTOR |
OK |
CHECK HARNESS AND CONNECTOR (SKID CONTROL ECU - REAR SPEED SENSOR)
Turn the engine switch off.
Make sure that there is no looseness in the locking part and connecting part of the connectors.
Disconnect the A13 skid control ECU (brake actuator assembly) connector.
Disconnect the U32 and/or T30 rear speed sensor connector.
Check the connector case and terminals for deformation and corrosion.
Standard condition |
