Start Clutch Check

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), and go to the A/T Mode Menu.

NOTE: If the HDS does not communicate with the PCM, troubleshoot the DLC circuit.





2. Choose Data List in the A/T Mode 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 5
^ If the HDS indicates Judder1 or Judder2, replace the CVTF, then go to step 3.

3. Choose Start Clutch Status Data Clear in Miscellaneous Test Menu, and clear the start clutch status with the HDS.
4. Choose Data List in A/T Mode 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), then go to step 5.
^ If the HDS indicates Ready, go to step 5.

5. Start the engine, and shift to the D position while pressing the brake pedal.
6. Accelerate from a stop at over 50% throttle (with 2.25 V of APP sensor voltage by monitoring the HDS), then slow down to a stop.
7. Repeat step 6 two times.
8. Choose Data List in the A/T Mode Menu, and make sure that the Start Clutch Status is Normal with the HDS.
9. To verify that the engine stalling and the judder when starting off does not occur, test-drive the vehicle for several minutes.
