DIAGNOSIS <TC-SST>

TSB Revision

TWIN CLUTCH- SPORTRONIC SHIFT TRANSMISSION (TC-SST)

22C-21

LOGIC FLOW CHARTS (Monitor Sequence)

.

DTC SET CONDITIONS

Check Conditions

• Voltage of battery: 8 V or more.

• Voltage of battery: 16.5 V or less.

JUDGMENT CRITERIA

• Fluid temperature: −50° C (−58° F) or less. (400

millisecond)

.

OBD-II DRIVE CYCLE PATTERN

The TC-SST-ECU temperature remains

−50° C

(

−58° F) or more for 400 milliseconds.

.

PROBABLE CAUSES

• Malfunction of TC-SST-ECU

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

STEP 2. Check whether the DTC is reset.
Q: Is DTC No. P0712 set?

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

P.22C-341

.)

NO : Intermittent malfunction. (Refer to GROUP 00

DTC P0713: TC-SST-ECU temperature sensor system (Output high range out)

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 output of the ECU tem-
perature sensor is normal.

.

DESCRIPTIONS OF MONITOR METHODS

The output of the ECU temperature is determined to
be too high.

.

MONITOR EXECUTION

• Continuous

DTC P0715: Input shaft 1 (odd number gear axle) speed sensor system (Output high range out)

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.
