STEP 3. Using scan tool MB991958, check the DTC
STEP 4. Check for wheel speed sensor <RL> installation
STEP 5. Check for wheel speed sensor <RL> output current
STEP 6. Check for wheel bearing looseness
STEP 7. Check of wheel speed detection encoder
Check the encoder for adhesion of foreign materials or deformation.Is the check result normal?
Go to Step 8. (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.
STEP 8. Check whether the DTC is set again.
