MONITOR DESCRIPTION
The skid control ECU (brake actuator assembly) has a speed sensor circuit self-diagnosis function.
When the vehicle is stopped, the speed sensor supply voltage exceeds a certain value, and the self-diagnosis function detects an incorrectly installed speed sensor, the skid control ECU (brake actuator assembly) illuminates the MIL and stores this DTC.

CONFIRMATION DRIVING PATTERN
NOTICE:
When performing the normal judgment procedure, make sure that the driver door is closed and is not opened at any time during the procedure.
HINT:
- After repair has been completed, clear the DTC and then check that the vehicle has returned to normal by performing the following All Readiness check procedure.
- When clearing the permanent DTCs, refer to the "CLEAR PERMANENT DTC" procedure.
- Connect the GTS to the DLC3.
- Turn the ignition switch to ON and turn the GTS on.
- Clear the DTCs (even if no DTCs are stored, perform the clear DTC procedure).
- Turn the ignition switch off.
- Turn the ignition switch to ON (READY) and turn the GTS on.
-
Wait for 3 seconds or more. [*]
HINT:
[*]: Normal judgment procedure.
The normal judgment procedure is used to complete DTC judgment and also used when clearing permanent DTCs.
-
Enter the following menus: Chassis / Brake/EPB* / Utility / All Readiness.
*: Electric Parking Brake System
-
Check the DTC judgment result.
HINT:
- If the judgment result shows NORMAL, the system is normal.
- If the judgment result shows ABNORMAL, the system has a malfunction.
- If the judgment result shows INCOMPLETE, perform driving pattern again.
PROCEDURE
|
1. |
CHECK PART NUMBER (REAR SPEED SENSOR RH) |
(a) Check that the rear speed sensor RH is installed.
OK:
Proper rear speed sensor RH is installed.
NOTICE:
If it is necessary to remove components in order to check the rear speed sensor RH, follow the relevant installation and removal procedures and precautions for those components.
HINT:
The rear speed sensor rotor RH and rear speed sensor RH are incorporated into the rear axle hub and bearing assembly RH. (for 2WD)
If the rear speed sensor rotor RH and rear speed sensor RH need to be replaced, replace them together with the rear axle hub and bearing assembly RH. (for 2WD)
