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 (FRONT SPEED SENSOR RH)
|
(a) Check that the front speed sensor RH is installed.
OK:
Proper front speed sensor RH is installed.
NOTICE:
If it is necessary to remove components in order to check the front speed sensor RH, follow the relevant installation and removal procedures and precautions for those components.
OK
