DIAGNOSIS <TC-SST>

TSB Revision

TWIN CLUTCH- SPORTRONIC SHIFT TRANSMISSION (TC-SST)

22C-133

DIAGNOSTIC PROCEDURE

STEP 1. Scan tool CAN bus diagnostics
Using scan tool MB991958, diagnose the CAN bus lines.
Q: Is the check result normal?

YES : Go to Step 2.
NO :  Repair the CAN bus lines. (Refer to GROUP 54C 

− 

Troubleshooting 

P.54C-14

.) After repairing the CAN 

bus line, go to Step 2.

STEP 2. Check whether the DTC is reset.
Q: Is DTC No. P182C set?

YES : Replace the TC-SST assembly. (Refer to 

P.22C-341

.)

NO :  Intermittent malfunction. (Refer to GROUP 00 

− How 

to Cope with Intermittent Malfunction 

P.00-15

.)

DTC P182D: Shift Fork Position Sensor 3 System (Neutral)

CAUTION

• If there is any problem in the CAN bus lines, 

an incorrect diagnostic trouble code may be 
set. Prior to this diagnosis, diagnose the CAN 
bus lines.

• Whenever the ECU is replaced, ensure that 

the CAN bus lines are normal.

.

DIAGNOSTIC FUNCTION

TC-SST-ECU checks that the shift fork position sen-
sor 3 is normal.

.

DESCRIPTIONS OF MONITOR METHODS

The shift fork position sensor 3 is determined to be 
abnormal.

.

MONITOR EXECUTION

• Continuous

.
