Twin Clutch-Sportronic Shift Transmission (TC-SST)
DIAGNOSIS [TC-SST]INTRODUCTION
The TC-SST system can exhibit any of the following symptoms: noise or vibration is generated or fluid leaks.
The causes of these symptoms could come from: incorrect mounting, the fluid level may be low, or a component of the TC-SST may be faulty.
TROUBLESHOOTING STRATEGY
Use these steps to plan your diagnostic strategy. If you follow them carefully, you will find most TC-SST malfunctions.
1. Gather as much information as possible about the complaint from the customer.
2. Verify that the condition described by the customer exists.
3. Check the vehicle for any TC-SST Diagnostic Trouble Codes (DTCs).
4. If you cannot verify the condition and there are no DTCs, the malfunction is intermittent.
5. If you can verify the condition but there are no DTCs, or the system cannot communicate with scan tool, refer to the Symptom Chart Symptom Chart.
6. If there is a DTC, record the number of the code, then erase the code from memory using scan tool.
7. Reconfirm the symptom.
8. If a DTC is set again, go to the Inspection Chart for Diagnostic Trouble Codes.
9. If a DTC is not set again, the malfunction is intermittent.
10. Verify malfunction is eliminated. After repairs are completed, the complaint conditions to confirm the malfunction has been eliminated.
PRECAUTIONS FOR DIAGNOSIS
With the TC-SST assembly, the IG shutoff delay system is adopted to improve the engine starting performance.
When the ignition switch is turned OFF, the IG shutoff delay system release the gear engagement in preparation for the next engine starting. This is a system to delay the engine stop for approximately 1 second, and the delay is not a malfunction.
If the gear is not in the reverse position, the R range indicator of the multi information display (a) and the R range indicator of the floor console panel (b) flash. This is a warning to the driver, and is not a malfunction.
In this case, return the shift lever to the N range, and move it to the R range again. If the flashing of each R range indicator changes to normal illumination, it indicates that the gear is in reverse position.
