DIAGNOSIS <TC-SST>

TSB Revision

TWIN CLUTCH- SPORTRONIC SHIFT TRANSMISSION (TC-SST)

22C-21

DIAGNOSTIC TROUBLE CODE PROCEDURES

DTC P0630: VIN not Recorded

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 chassis number is nor-
mal.

(TC-SST-ECU receives chassis number information 
from the engine control module via CAN, and write to 
TC-SST-ECU.)

.

DESCRIPTIONS OF MONITOR METHODS

The chassis number is determined to be written 
abnormally.

.

PROBABLE CAUSES

• The CAN bus line is defective.
• Malfunction of engine control module
• Malfunction of TC-SST-ECU

DIAGNOSTIC PROCEDURE

Required Special Tools:

• MB991958 Scan Tool (M.U.T.-III Sub Assembly)

• MB991824: Vehicle Communication Interface (V.C.I.)
• MB991827 M.U.T.-III USB Cable
• MB991910 M.U.T.-III Main Harness A

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-15

.) After repairing the CAN 

bus line, go to Step 2.

STEP 2. Scan tool diagnostic trouble code
Check the engine diagnostic trouble code. (Refer to GROUP 
13A − Troubleshootin

P.13A-48

.)

Q: Is the DTC set?

YES : Perform the relevant troubleshooting.
NO :  Go to Step 3.

STEP 3. Check whether the DTC is reset.
Q: Is DTC No. P0630 set?

YES : Replace the mechatronic assembly. (Refer to 

P.22C-421

.)

NO :  Intermittent malfunction. (Refer to GROUP 00 − How 

to Cope with Intermittent Malfunction 

P.00-15

.)

DTC P0701: EEPROM System (Malfunction)

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 EEPROM and RAM in 
the TC-SST-ECU is normal.

.

DESCRIPTIONS OF MONITOR METHODS

.) After repairing the CAN 

bus line, go to Step 2.

STEP 2. Check whether the DTC is reset.
Q: Is DTC No. P0701 set?

YES : Replace the mechatronic assembly. (Refer to 

P.22C-421

.)

NO :  Intermittent malfunction. (Refer to GROUP 00 − How 

to Cope with Intermittent Malfunction 

P.00-15

.)

DTC P0702: Internal control module, monitoring processor system (Malfunction)

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 internal module and 
monitoring processor are normal.

.

DESCRIPTIONS OF MONITOR METHODS

The internal module and monitoring processor are 
determined to be abnormal.

.
