Thread: Ace Fault Help

I had a similar issue with a seat belt pretensioner fault if you back out of the system and go back in you may find it is clear

Don't get stressed untill you dont try with hawkeye or T4 if you have the chance... i have both testers and i can declare without any remorse that nanocom is not quite reliable when it comes to ACE, also the ACE ECU is not the most well engineered unit... as long as the warning light is not on it means that fault is hystorical not active so dont eat your nervs with it

So my guess is that the fault is still present so it clears it and then re-reads it and logs it.

Can anyone confirm this and does anyone know where or what the fault might be?

Nanocom I somtimes wonder, I had faults that Nanocom did not clear, and then plugged in my Hawkeye and cleared them just fine.
I find Nanocom sometimes decides to lose communications with ECUs for some reason. So I use both Nanocom and Hawkeye on my D2

How long since you've serviced the ace filter Dave?

Haven't yet done it, but it is on my to do list. Where are they?

And yes I know I can find it in "The Good Oil"
