Audi 200 turbo quattro avant 10vt.
The ECU suffered damage: the EC36/28 output was broken. Likely due to HALL sensor connection problem. ECU output fixed (regulator swapped). Other ECU functions seem unaffected.
Before install can continue, fill in ALL outputs (injection and ignition as well!)
36/1: tps in
36/2: iat in
36/3: tacho out
36/4: fuel relay
36/14: clt in
36/27: primary trigger
36/28: +5V supply (what does "not working" mean ? Is it shorted to ground ?) Check with DVM diode mode that it's not shorted to ground or +12V
36/29: tps supply (not working)
ground: 36/5,21,22,26,32
iac 5.54kohm at 4C
clt 5.45kohm at 4C
ground checked to battery. all 0.3 ohm
36/19 iac (checked to another injector outs.. 11.2 ohm)
36/24 iac
Injector outputs Fill them in. All 5 injectors
- ... cyl3
- 36/9 inj cyl 5
- ... cyl4
- ... cyl2
- ... cyl1
TODO: Measure this: EC36/23 flyback must be connected to injector common (even with ignition off)
Ignition outputs Fill them in
36/35 coil logic level or power IGBT output needed ?
distributer ? If not, fill in:
- ... cyl3
- ... cyl5
- ... cyl4
- ... cyl2
- ... cyl1
