Start Clutch Check
NOTE:
If the transmission acts abnormally when the vehicle starts off, check the start clutch with the HDS.
- Connect the HDS to the DLC (A) located under the driver's side of the dashboard.
- Turn the ignition switch to ON (II).
- 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 (see DLC CIRCUIT TROUBLESHOOTING ).
- 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 (see CVT FLUID REPLACEMENT ), then go to step 5.
- Select Start Clutch Status Data Clear in the Miscellaneous Test Menu, and clear the start clutch status with the HDS.
- 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.
- Start the engine, and shift the shift lever to D, while pressing the brake pedal.
- 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.
- Repeat step 8 two times.
- Select Data List in the A/T SYSTEM Menu, and make sure that the Start Clutch Status is Normal with the HDS.
- 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.
