P2762
DTC P2762 Lock-up solenoid system circuit (performance)DTC P2763 Lock-up solenoid system circuit (High)
DTC P2764 Lock-up solenoid system circuit (Low)
Circuit description
The lock-up control solenoid (SLU) is controlled by the duty signal which is predetermined by the transmission control computer ASSY. Then, lock-up and flex lock-up control is performed.
Monitor description
If open or short circuit is detected in the shift solenoid valve SLU circuit, TCM recognizes it as a defect. TCM turns on MIL and records the diagnostic code.
