DIAGNOSIS <TC-SST>

TSB Revision

TWIN CLUTCH- SPORTRONIC SHIFT TRANSMISSION (TC-SST)

22C-129

DTC P182B: Shift Fork Position Sensor 3 System (Voltage 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 voltage of the shift fork 
position sensor 3 is normal.

.

DESCRIPTIONS OF MONITOR METHODS

The voltage of the shift fork position sensor 3 is too 
high.

.

MONITOR EXECUTION

• Continuous

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

• Position sensor voltage: 3.008 V or more. (160 

millisecond)

.

OBD-II DRIVE CYCLE PATTERN

The position sensor voltage remains 3.008 V or less 
for 160 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 

− 

Troubleshooting 

P.54C-14

.) After repairing the CAN 

bus line, go to Step 2.

STEP 2. Check whether the DTC is reset.
Q: Is DTC No. P182B set?

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

P.22C-341

.)

NO :  Intermittent malfunction. (Refer to GROUP 00 

− How 

to Cope with Intermittent Malfunction

TWIN CLUTCH- SPORTRONIC SHIFT TRANSMISSION (TC-SST)

22C-131

DTC P182C: Shift Fork Position Sensor 3 System (Output 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 shift fork 
position sensor 3 is normal.

.

DESCRIPTIONS OF MONITOR METHODS

The output of the shift fork position sensor 3 is deter-
mined to be abnormal.

.

MONITOR EXECUTION

• Continuous
