DIAGNOSIS <SHIFT LEVER>

TSB Revision

TWIN CLUTCH- SPORTRONIC SHIFT TRANSMISSION (TC-SST)

22C-321

STEP 4. Check the wiring harness between C-27 shift 
lever-ECU connector terminal No. 8 and body ground.
Check the ground line for open circuit.
Q: Is the check result normal?

YES : Go to Step 5.
NO :  Repair the wiring harness.

STEP 5. Measure the voltage at C-27 shift lever-ECU 
connector.
Disconnect the connector, and measure the voltage between 
terminal No. 12 and ground at the wiring harness side.

OK: Battery positive voltage

Q: Is the check result normal?

YES : Go to Step 8.
NO :  Go to Step 6.

STEP 6. Shift lever-ECU connector check: C-27
Check for the contact with terminals.
Q: Is the check result normal?

YES : Go to Step 7.
NO :  Repair the defective connector.

STEP 7. Check the wiring harness between C-27 shift 
lever-ECU connector terminal No. 12 and fusible link No. 
36.
Check the power supply line for short or open circuit.
Q: Is the check result normal?

YES : Go to Step 8.
NO :  Repair the wiring harness.

STEP 8. Scan tool diagnostic trouble code
Check the ETACS diagnostic trouble code. (Refer to GROUP 
54A 

− Troubleshooting 

P.54A-582

.)

Q: Is the DTC set?

YES : Perform the relevant troubleshooting.
NO :  Go to Step 9.

STEP 9. Measure the voltage at C-27 shift lever-ECU 
connector.
(1) Disconnect the connector, and measure the voltage 

between terminal No. 13 and ground at the wiring harness 
side.

(2) Turn the ignition switch to the "ON" position.

OK: Battery positive voltage

Q: Is the check result normal?

YES : Go to Step 12.
NO :  Go to Step 10.

TWIN CLUTCH- SPORTRONIC SHIFT TRANSMISSION (TC-SST)

22C-322

STEP 10. Inspection of the shift lever-ECU connector, 
intermediate connector, and ETACS-ECU connector: C-27, 
C-131, C-317
Check for the contact with terminals.
Q: Is the check result normal?

YES : Go to Step 11.
NO :  Repair the defective connector.

STEP 11. Check the wiring harness between C-27 shift 
lever-ECU connector terminal No. 13 and C-317 
ETACS-ECU connector terminal No. 5.
Check the power supply line for short or open circuit.
Q: Is the check result normal?

YES : Go to Step 12.
NO :  Repair the wiring harness.

STEP 12. Retest the system.
Q: Does a malfunction take place again?

YES : Replace the shift lever assembly. (Refer to 

P.22C-334

.)

NO :  Intermittent malfunction. (Refer to GROUP 00 

− How 

to Cope with Intermittent Malfunction 

P.00-15

.)
