Hi all, trying to get my AWD system working properly after a soup to nuts rebuild. The computer is throwing codes 8, 9 (ABS was deleted) and also code 18 which seems to be the issue. Today we tried the bleed procedure and still doesn’t work.
Here’s the description from the builder: on ignition the pump pumps oil, when the pressure reaches the desired value, the pump turns off and the oil is stored in the tank by closing the check valve, in our case it seems to me that it does not work and when the pump pumps up the pressure to the operating level , the sensor turns it off and the liquid is squeezed back through the pump into the tank, you can even hear the pump spinning in the opposite direction, the pressure decreases and the sensor turns on the pump again, and this all repeats endlessly.
The AWD system worked after I bought the car but not since the rebuild. I changed the G sensor to the Do-Luck unit, maybe that could also be the issue? It’s a pain to change so we haven’t tried it yet
Hopeful to get this worked out, I really wanted an AWD skyline. Thanks 🙏
