STEP 2. Using scan tool (M.U.T.-IIISE), check the data list.
(1) Turn off the power supply mode of the electric motor switch.
(2) Operate the electric motor switch twice without depressing on the brake pedal and turn on the power supply mode.
(3) Wait at least 10 seconds.
(4) Check that the following data list display contents are normal (Refer to ).OK: 500 r/min
note | If the power supply mode is on (not in the READY state), the water pump does not rotate. However, if you check the data list using the scan tool (M.U.T.-IIISE) in that state, it shows that the rotation speed of the water pump is 500 r/min although it is not rotating. |
Is the check result normal?
Go to Step 3. Replace the water pump (Refer to GROUP 14B - Water Pump Removal and Installation ). Then go to Step 3.
