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.

DIAGNOSTIC TROUBLE CODE CHART
M1225000600027
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.

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
.) 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
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
.)
NO : Intermittent malfunction. (Refer to GROUP 00 − How
to Cope with Intermittent Malfunction
.)
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.
• Whenever the ECU is replaced, ensure that
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.
.
PROBABLE CAUSES
• Malfunction of the shift lever-ECU
• Malfunction of the lever position sensor

STEP 2. Check whether the DTC is reset.
Q: Are DTC Nos. P198E, P198F set?
YES : Replace the shift lever assembly. (Refer to
.)
NO : Intermittent malfunction. (Refer to GROUP 00 − How
to Cope with Intermittent Malfunction
