DIAGNOSIS <SHIFT LEVER>

TSB Revision

TWIN CLUTCH- SPORTRONIC SHIFT TRANSMISSION (TC-SST)

22C-369

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.

CAUTION

During diagnosis, a DTC associated with other system may be set when the ignition switch is turned 

ON with connector(s) disconnected. On completion, confirm all systems for diagnostic trouble 

code(s). If diagnostic trouble code(s) are set, erase them all.

CAUTION

During diagnosis, a DTC associated with other system may be set when the ignition switch is turned 

ON with connector(s) disconnected. On completion, confirm all systems for diagnostic trouble 

code(s). If diagnostic trouble code(s) are set, erase them all.

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.

.

PROBABLE CAUSES

• Malfunction of the shift lever-ECU
• Generator malfunction

DTC No.

DIAGNOSIS <SHIFT LEVER>

TSB Revision

TWIN CLUTCH- SPORTRONIC SHIFT TRANSMISSION (TC-SST)

22C-371

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 3.
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. Check whether the DTC is reset.
Q: Is DTC No. P0563 set?

YES : Go to Step 3.
NO :  This diagnosis is complete.

STEP 3. Generator system check
Refer to GROUP 16 − Charging System, On-vehicle Service 

P.16-7

.

Q: Is the check result normal?

YES : Go to Step 4.
NO :  Repair or replace the generator related parts.

STEP 4. Check whether the DTC is reset.
Q: Is DTC No. P0563 set?

YES : Shift lever assembly replacement. (Refer to 

P.22C-404

.)

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

to Cope with Intermittent Malfunction 

P.00-15

.)

DTC P198D: EEPROM 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 EEPROM or RAM is 
normal.

.

DTC SET CONDITIONS

The EEPROM writing data is determined to be 
abnormal.

.

PROBABLE CAUSES

• Malfunction of the shift lever-ECU

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.

the CAN bus lines are normal.

.

OPERATION

The shift lever-ECU has lever position sensors, and 
checks for abnormality.

.

DTC SET CONDITIONS

• When one position signal is determined not to be, 

P198E is set.

• When two position signals are determined not to 

be, P198F is set.
