DIAGNOSIS <TC-SST>
TSB Revision
TWIN CLUTCH- SPORTRONIC SHIFT TRANSMISSION (TC-SST)
22C-185
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
.) After repairing the CAN
bus line, go to Step 2.
STEP 2. Check whether the DTC is reset.
Q: Is the DTC No. P1855 set?
YES : Replace the TC-SST assembly. (Refer to
NO : Intermittent malfunction. (Refer to GROUP 00
− How
to Cope with Intermittent Malfunction
.)
DTC P1857: Odd number gear axle interlock
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 gear engagement is
normal.
.
DESCRIPTIONS OF MONITOR METHODS
The two gears are determined to be engaged in the
odd number gear range.
.

DTC SET CONDITIONS
Check Conditions
• Voltage of battery: 8 V or more.
• Voltage of battery: 16.5 V or less.
• Engine speed: 500 r/min or more.
• Time since above engine condition: 400 millisec-
ond or more.
JUDGMENT CRITERIA
• Shift fork 1 and 2 position: 3.8 mm (0.15 inch) or
more. (500 millisecond)
.
