Fault code 9? (MAS controller)
 

Hi!
I made a homebrew fault code reader last week..
Plugged it in (socket 14) and got 9 blinks, the analog code table shows that I got a circuit 50 failure.. But what does it mean?
Is my MAS controller broke.. :confused:

Everything else seems to be ok (at socket 3 & 8).(I have a 16-pin connector).

I've started to notice a rough idle some weeks ago, my duty cycle fluctuate around 20-30% at idle.. can the MAS have something to do with it?

I cleared the fault code memory and now I got 1 blink = ok!
the circuit 50 failure hasnt showed up after that.
and now, after I have cleared the memory my dutycycle is around 46-54%...strange!

My idle and HC is still not perfect, but that is probably related to some other problems. Shall check the distcap, rotor, coil and wires tomorrow.
