DIAGNOSIS <TC-SST> TSB Revision TWIN CLUTCH- SPORTRONIC SHIFT TRANSMISSION (TC-SST) 22C-41 DIAGNOSTIC PROCEDURE STEP 1. Scan tool CAN bus diagnostics YES : Go to Step 2. − Troubleshooting .) After repairing the CAN bus line, go to Step 2. STEP 2. Check whether the DTC is reset. YES : Replace the TC-SST assembly. (Refer to NO : Intermittent malfunction. (Refer to GROUP 00 − How to Cope with Intermittent Malfunction .) DTC P0841: Clutch 1 Pressure Sensor System (Poor performance) CAUTION • If there is any problem in the CAN bus lines, an incorrect diagnostic trouble code may be • Whenever the ECU is replaced, ensure that the CAN bus lines are normal. .
