Hi to everyone everyone!
I’m writing from Southern Italy and I thank you all very much in advance for any help you can give me to solve my big problem with the KK.
Let me explain my ordeal in the hope that someone can point me in the right direction:
I bought the KK, with a 110.000milage, knowing the clutch needed to be redone and that the “Service 4WD” light would go off by itself after 1-2 minutes of driving, and otherwise 2WD, 4WD and 4WD-Low all worked normally...instead if i turn on the engine and don't move the "Serv 4WD" lamp stay on and conseguently I can't switch the T-CASE in any position...like a fool I thought that was normal. But in hindsight, if I leave the vehicle in a puddle in 2WD, turn it off, and restart it, I can’t switch into 4WD.
I’ve been an idiot.
Anyhow, the fault code being displayed is C140A.
In the meantime I’ve had the clutch rebuilt and all oils changed—including the transfer case and differentials—and ever since then, instead of the “Serv 4WD” light and the C140A error disappearing after a few meters, they now only go away if I make a sharp left turn or a left-hand roundabout; if I turn right, they stay on.
The problem comes back as soon as I shut off and restart the car.
Following the workshop manual, they checked the resistance values at the connector to rule out shorts, and everything is fine.
I’ve replaced the 4WD control unit with a brand-new original one with updated firmware.
I’ve replaced the transfer-case motor with a new non-OEM unit.
And the problem remains…
Does anyone have a suggestion?
Regards, Giovanni.
