Clutch: Testing and Inspection

Start Clutch Check

NOTE: If the transmission acts abnormally when the vehicle starts off, check the start clutch with the HDS.

1. Connect the HDS to the DLC (A) located under the driver's side of the dashboard.





2. Turn the ignition switch to ON (II).

3. Make sure the HDS communicates with the PCM, and go to the A/T Data List. If it does not, go to the DLC circuit troubleshooting DLC Circuit Troubleshooting (PGM-FI System).

4. Select Data List in the A/T SYSTEM Menu, and monitor the Start Clutch Status with the HDS.

- If the HDS indicates Normal, the start clutch is OK, then disconnect the HDS.
- If the HDS indicates Unchecked, go to step 7.
- If the HDS indicates Judder1 or Judder2, replace the CVTF CVT Fluid Replacement, then go to step 5.

5. Select Start Clutch Status Data Clear in the Miscellaneous Test Menu, and clear the start clutch status with the HDS.

6. Select Data List in A/T SYSTEM Menu, and monitor the Start Clutch Status Diagnosis condition with the HDS.

- If the HDS indicates Not ready, warm up the engine to normal operating temperature (the radiator fan comes on twice), then go to step 7.
- If the HDS indicates Ready, go to step 7.

7. Start the engine, and shift the shift lever to D, while pressing the brake pedal.

8. Accelerate from a stop at over 50% throttle (with 2.75 V of the APP sensor voltage by monitoring APP Sensor A (V) with the HDS), then slow down to a stop.

9. Repeat step 8 two times.

10. Select Data List in the A/T SYSTEM Menu, and make sure that the Start Clutch Status is Normal with the HDS.

11. Test-drive the vehicle for several minutes, make sure the engine does not stall or flare when starting off, and verify that a problem does not occur on the start clutch pressure control system.
