DIAGNOSIS <TC-SST>
TSB Revision
TWIN CLUTCH- SPORTRONIC SHIFT TRANSMISSION (TC-SST)
22C-325
STEP 2. Check whether the DTC is reset.
Q: Is DTC No. P2814 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 P2815: Clutch/Shift Switching Solenoid 2 System (Short to power supply)
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 clutch/shift switching
solenoid 2 circuit is normal.
.
DESCRIPTIONS OF MONITOR METHODS
The clutch/shift switching solenoid 2 circuit is deter-
mined to be short to power supply.
.
MONITOR EXECUTION
• Continuous
