DTC P2759 Solenoid Control Circuit Electrical (Shift Solenoid Valve SLU)

DESCRIPTION
The amount of current flow to the solenoid is controlled by the (*) duty ratio of the ECM output signal. The higher the duty ratio becomes, the higher the lock-up hydraulic pressure becomes during the lock-up operation.





(*) Duty Ratio
The duty ratio is the ratio of the period of continuity in one cycle. For example, if A is the period of continuity in one cycle, and B is the period of non-continuity, then Duty Ratio = A/(A+B) x 100(%).

DTC Detection Condition:

Reference (Using an oscilloscope):
Check the waveform between the terminals SLU+ and SLU- of the ECM connector





Standard: Refer to the illustration.





MONITOR DESCRIPTION
When an open or short in a shift solenoid valve (SLU) circuit is detected, the ECM determines there is a malfunction. The ECM will turn on the MIL and store this DTC.
