Morning Everyone
I was just wondering if any one can guide me on this issue I am having with my awd system on my r32 gts4.
When I bought the car the awd system never worked and last night I thought I start playing doctor and see what is causing this system not to work.
So Symptoms
1. When you turn the key on no AWD or Hicas lights come on,
2. Checked 10A fuse under Dash, Fuse is good ( Continuity ) but once u plug it in there is no power or Continuity.
3. Ecu no red light on & no wires cut
4. Fuse under hood ( anti-skid 30am) no continuity or power when key is turned on
5. Relay in the truck next to the latch has power but no continuity
6. I bypassed the Relay, pump comes on but if you hold it there for a while it makes a nasty noise...
7. There is fluid in Tank located in the truck
I found a Attesa ECU wiring Diagram and will be working on it tonight, with searching I found that pin 42 sometimes need to be grounded.
This video Helped a lot.
I need to Test the power wire to ECU and trace the wire from fuse box under dash to its power and ground, but if any one has had this issue it be great help save me some time and money.
Cheers
Rob
