Mitsubishi Lancer Evolution X. Manual — part 517

DIAGNOSIS <TC-SST>

TSB Revision

TWIN CLUTCH- SPORTRONIC SHIFT TRANSMISSION (TC-SST)

22C-25

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. Check whether the DTC is reset.
30 seconds after turning ON the ignition switch, check that the
diagnostic trouble code is reset.
Q: Is DTC No. P0712 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 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

.

MONITOR EXECUTION CONDITIONS

in memory for the item monitored below)

• P0712: TC-SST-ECU temperature sensor system

(Output low range out)

• P1808: TC-SST-ECU temperature, fluid tempera-

ture sensor system (Correlation error)

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.

• Whenever the ECU is replaced, ensure that

the CAN bus lines are normal.

.

DIAGNOSTIC FUNCTION

TC-SST-ECU checks that the input shaft 1 (odd num-
ber gear axle) speed sensor is normal.

.

DESCRIPTIONS OF MONITOR METHODS

The output of the input shaft 1 (odd number gear
axle) is determined to be too high.
