DIAGNOSIS <SHIFT LEVER>

TSB Revision

TWIN CLUTCH- SPORTRONIC SHIFT TRANSMISSION (TC-SST)

22C-301

FAIL-SAFE FUNCTION

If an abnormality occurs to the signal of sensors, 
switches, solenoids, or others, the shift lever-ECU 
performs a control for the driver safety and system 
protection. The control contents are as follows.

FAIL-SAFE REFERENCE TABLE

HOW TO CONNECT THE SCAN TOOL (M.U.T.-III)

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 (Vehicles with 

CAN communication system)

CAUTION

To prevent damage to scan tool MB991958, always turn the 
ignition switch to the "LOCK" (OFF) position before con-
necting or disconnecting scan tool MB991958.
1. Ensure that the ignition switch is at the "LOCK" (OFF) 

position.

2. Start up the personal computer.
3. Connect special tool MB991827 to special tool MB991824 

and the personal computer.

4. Connect special tool MB991910 to special tool MB991824.
5. Connect special tool MB991910 to the data link connector.
6. Turn the power switch of special tool MB991824 to the "ON" 

position.
NOTE: When special tool MB991824 is energized, special 
tool MB991824 indicator light will be illuminated in a green 
color.

7. Start the scan tool system on the personal computer.
NOTE: Disconnecting scan tool MB991958 is the reverse of the 
connecting sequence, making sure that the ignition switch is at 
the "LOCK" (OFF) position.

FREEZE FRAME DATA CHECK

Various data of when the diagnostic trouble code is determined 
is obtained, and the status of that time is stored. By analyzing 
each data using the scan tool, troubleshooting can be per-
formed efficiently.
Display items of the freeze frame data are as follows.

Code No.

Item

Control content

P198D

EEPROM

Normal driving can be performed, and displays an occurrence of 
trouble to the multi information display to warn the driver.

P198E

Lever position sensor 
system (Malfunction of 
one sensor)

Normal driving can be performed, and displays an occurrence of 
trouble to the multi information display to warn the driver.

P198F

Lever position sensor 
system (Malfunction of 
two sensors)

The lever position cannot be identified, and the clutch open at TC-SST 
side prohibits the vehicle from driving. Then displays an occurrence of 
trouble to the multi information display to warn the driver.

DIAGNOSTIC TROUBLE CODE PROCEDURES

DTC P0563: Power Supply System

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.

.

OPERATION

The shift lever-ECU checks that the power supply cir-
cuit is normal.

.

DTC SET CONDITIONS

The voltage from the battery is determined to be 
overvoltage.

.

DTC P198E, P198F: Lever Position Sensor System

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.
