DIAGNOSIS
TSB Revision
ACTIVE STABILITY CONTROL SYSTEM (ASC)
35C-81
STEP 2. DTC recheck after repairing the CAN bus line
Q: Is DTC C102A set?
YES : Go to Step 3.
NO : This diagnosis is complete.
STEP 3. Scan tool diagnostic trouble code
Check if DTC No. C1020 is also set.
Q: Is DTC C1020 also set?
YES : Carry out the diagnosis for code No. C1020. ( Refer to
P.35C-35
.)
NO : Go to Step 4.
STEP 4. Check of wheel speed sensor installation status
Check the installation status of wheel speed sensor <RL> (dis-
connection of wheel speed sensor, looseness of mounting bolt,
etc.).
Q: Is the check result normal?
YES : Go to Step 5.
NO : Reinstall the wheel speed sensor <RL> correctly.
(Refer to
P.35C-300
.) Then go to Step 9.
STEP 5. Check of wheel speed sensor as a single unit
Refer to
P.35C-303
.
Q: Is the check result normal?
YES : Go to Step 6.
NO : Replace the wheel speed sensor <RL>. (Refer to
P.35C-300
.) Then go to Step 9.
STEP 6. Wheel bearing looseness check
NOTE: Wheel bearing looseness may increase the gap
between the wheel speed sensor and the wheel speed detec-
tion magnet encoder. Check the wheel bearing <RL> for loose-
ness. (Refer to GROUP 27
−
On-vehicle Service
P.27-32
.)
Q: Is the check result normal?
YES : Go to Step 7.
NO : Replace the rear wheel hub assembly. (Refer to
GROUP 27 − Rear Axle Hub Assembly
P.27-35
.)
STEP 7. Check of wheel speed detection encoder
Check the encoder for adhesion of foreign materials or defor-
mation.
Q: Is the check result normal?
YES : Go to Step 8.
NO (Adhesion of foreign materials) : Clean the encoder
so as not to disturb the magnetization pattern on the
encoder while taking care of the magnet, magnetic
substance, and magnetic attraction.
NO (Deformation) : Replace the rear wheel hub assembly.
