I tested my entire 4wd system-
Actuator works with vacuum actuation
Solenoids click when manually engerized
All the vacuum lines and canister hold vacuum.
As soon as the selector goes into 4wd the lights flash. The solenoids have positive voltage on each terminal no matter what the position of the 4wd selector.
I would assume they are supposed to get a ground signal when the selector is moved but I can’t find any documentation on how the ecu functions
Does anyone have an answer?
