I have a R33 GTR which displays the AWD and A-LSD warning lights. The 4wd is not functioning so the errors seems correct.
The computer at the rear flashes 7 slow then 5 fast, this seems to be
1,5 Front right wheel sensor and circuit
3,7 Rear right wheel sensor and circuit

The error started happening intermittently at first, now it occurs every time I start the car. If I engage the starter motor before the fuel pump has finished I often get the ABS warning light to appear as well.
I have topped up the Reservoir in the boot to a little over full when ignition is on, no change.
I have changed green 30A fuses around in the boot to no success and both looked good.
I know I can bleed the system but the error codes do not seem to say this is the problem.
Where else do people think I should look?
