MONITOR DESCRIPTION
The No. 2 skid control ECU (brake actuator assembly) monitors the output value of the speed sensors. When the vehicle is being driven and a sudden irregular change in acceleration due to iron particles being attached to the speed sensor is detected repeatedly, or periodic sudden changes in acceleration due to iron particles being attached to the speed sensor rotor is detected, the No. 2 skid control ECU (brake actuator assembly) judges that speed sensor noise is occurring and illuminates the MIL and stores this DTC.
Also, when the vehicle is being driven and the output value of the speed sensor is momentarily interrupted repeatedly, the No. 2 skid control ECU (brake actuator assembly) judges that there is a momentary interruption in the speed sensor circuit and 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.
-
Drive the vehicle straight at a speed of 20 km/h (12 mph) or more for 15 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.
-
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.
CAUTION / NOTICE / HINT
NOTICE:
-
After replacing or removing and installing a speed sensor, perform Dealer Mode (Signal Check) inspection to confirm that the speed sensors are operating correctly.
