Attessa Codes

[blind_elk]

I'm starting to get the ATTESSA / HICAS warning lights combination on (cold) startup. Generally, if I stop then re-start the engine, the error goes away.

ATTESSA reservoir level is OK.

I checked the ATTESSA ECU (that's the one on the passenger side?) for an error code - all I get is 1 flash every 3 seconds. What does that mean?

i havent got the codes on me, but i think three will be one of the wheels sensors have a fault.

lol have you memorised the bloody things Russ?

1 is right front wheel speed sensor, it is at the hub.

But do you have ABS? I would have thought it would be on as well since it uses the wheel speed sensor too.

[blind_elk]

Yes, probably is the ABS, not HICAS error.

So, possibly a bad earth or something similar? Might be a bad battery - been having some trouble starting recently. High charge rate might indicate a problem to the ATTESSA ECU. Who knows what Nissan built into these things.

i know 11 and 12 are the g sensors, i get them all the time but i enjoy rocking the rwd action from time to time

I've never had trouble with them.

This is what nissan says

I have had trouble caused by a bad earth before, so maybe bad voltage is giving you intermittent problems too.

Seems as though it is probably battery related. If I let the engine run for a few minutes, then stop and immediately re-start the engine, I don't have the problem.
