clutch inside the torque converter is operated, and the pump impeller and turbine runner are connected. Through this, the engine and the automatic
transmission are coupled and engine output is connected directly to the automatic transmission, eliminating transmission loss. By sliding the
lock-up clutch when lock-up is in the OFF range, extends the lock-up range to low vehicle speeds. It also suppresses a rise in engine speed and
increases transmission efficiency, improving fuel economy and at the same time, through the sliding of the lockup clutch, engine vibration can be
absorbed by the torque converter.

P2762
The TCM detects the error current more than 80 mA for 2.75 ms.
P2763
The TCM detects at least 5 times less than 23 mA current consumption of the SLU control circuit for 100 ms.
P2764
The TCM detects at least 5 times more than 1.333 A current consumption of the SLU control circuit for 100 ms.
Action Taken When the DTC Sets
P2759, P2762
* DTCs P2759 and P2762 are Type B DTCs.
