I suspect it’s your rubber hoses leaking still, or the t case switch.
Hello friend, I don't know what to do. I'm going to update you on everything I've done and they still keep flashing.
- new front actuator switch, new selenoids,
- check and clean all transmission and transfer
- case connections,
- check the vacuums with a manual vacuum pump, - check the plugs that connect to the selenoids,
- check the connections and wiring of the ECU that is behind the glove box.
- clean and grease actuator pin.
Everything I checked there was nothing bad or defective, the vacuum lines are ok
The only thing I saw and I don't know if it has anything to do with it is a blocked vacuum connection, but one of the ones on the elnoid engine delenoids, which has green spots. Photo 1
And of the selenoid lines, the only one that could not hold pressure was the one that goes to the connections that go to the engine photo 3 color pink, and checking that line I saw a white non-return valve, I think that may be the problem. Photo 2
another thing my delics have an oil catch can
and when I start the vehicle I don't feel a vacuum in any of the hoses as if no air was passing through there, that is, dead.
I do not know what to do
