ACTIVE STABILITY CONTROL SYSTEM (ASC)
DIAGNOSIS
STEP 4. Check of wheel speed detection encoder
Check the encoder for adhesion of foreign materials or deformation.
Oil seal
Magnetic
encoder
Wheel
bearing
AC504925 AC
Q: Is the check result normal?
YES : Go to Step 5.
NO (Adhesion of foreign materials) : Remove the foreign
materials and clean the encoder so as not to disturb
the magnetization pattern on it while taking care of the
magnet, magnetic substance, and magnetic
attraction. When the encoder is deformed, replace the
wheel bearing.
NO (Deformation) : Replace the wheel bearing (Refer to
GROUP 26 −Front axle hub assembly P.26-16).
STEP 5. Check whether the DTC is reset.
(1) Erase the DTC.
(2) Drive the vehicle at 12 mph (20 km/h) or more.
NOTE: The ABS warning light does not turn OFF in some
cases unless the vehicle runs at 12 mph (20 km/h) or
higher.
Q: Is DTC C1041 set?
YES : Replace the hydraulic unit (ASC-ECU) (Refer to
P.35C-311). Then go to Step 6.
NO : Intermittent malfunction (Refer to GROUP 00 −How to
Cope with Intermittent Malfunction P.00-13).
STEP 6. Check whether the DTC is reset.
(1) Erase the DTC.
(2) Drive the vehicle at 12 mph (20 km/h) or more.
NOTE: The ABS warning light does not turn OFF in some
cases unless the vehicle runs at 12 mph (20 km/h) or
higher.
Q: Is DTC C1041 set?
YES : Return to Step 1.
NO : The procedure is complete.
