R33 Attesa Troubleshooting

When putting my R33 gts4 on the dyno I've discovered that the 4WD is not working.  It might have actually been broken for awhile, it would explain my poor 60ft times when I was drag racing last year (a month before I had the engine rebuilt).  However in general driving I've only ever seen 4WD become active twice in the 7 years I've owned the car - I don't drive it hard on the street.  That said the 4WD light wasn't on and I know it worked because when I had an ABS sensor go it did light up.  I've now switched out my gtr ecu for a Link G4+ and a dash2pro so I don't know how to fault find on the attesa system anymore - does anyone have any ideas?

Fault finding on the Attessa is done on the Attessa  ECU where there is alleged to be a blinking light (haven't done it myself). If you haven't already you need to run a wire from the TPS to the Atessa ECU when you fit a Link. Have you checked the reservoir level? Tried bleeding it (one nipple at the back of the gearbox another above the diff)?

Doesn't the needle move? That would've been a good indicator.

Probably needs a good bleed or something died (pump?).

GTS-4 doesn't have an indicator like the GTR sadly.  

 

I have check fluid levels and they are fine.  I'll try bleeding the system.  Attesa to TPS has been done.  I'll try and find the ecu and see if there is a blinking light on it.

What the shit? Oh yeah, R33 has it in the centre triple gauges. My bad.
