DIAGNOSTIC FUNCTION


CVT-ECU conducts fault detection by monitoring the terminal voltage of the CVT fluid temperature sensor.

JUDGEMENT CRITERIA



PROBABLE CAUSES



DIAGNOSIS PROCEDURE

STEP 1. Check the following connector

  • CVT assembly connector
  • CVT-ECU connector
Check the terminals for a contact status problem and internal short circuit.

Q. Is the check result normal?
Go to Step 2.
Repair the defective connector.

STEP 2. Check for open circuit in SPWR and SGND line between the CVT assembly connector and the CVT-ECU connector

Q. Is the check result normal?
Go to Step 3.
Repair the wiring harness.

STEP 3. CVT fluid temperature sensor check
Refer to .

Q. Is the check result normal?
Go to Step 4.
Replace the CVT assembly.

STEP 4. CVT fluid temperature sensor continuity check
Disconnect the CVT assembly connector, and then check that there is no continuity between the sensor-side terminal No. 12 and the transmission case.

Q. Is the check result normal?
Go to Step 5.
Replace the CVT assembly.

STEP 5. Symptom recheck after erasing diagnosis code

Q. Is the diagnosis code stored?
Replace the CVT-ECU.
Intermittent malfunction (Refer to GROUP 00 - How to Cope with Intermittent Malfunctions .).
