Searching fuse/relay box for DCHA..
2 Attachment(s)
To keep the troops busy I have yet another question :D
I cant find a reason why my DCHA is not working so I dived into my fuse/relay box .. But I can't see a fuse or relay about a DCHA or Auxilery Heater. :confused: Methinks the "fuel heater" would be the only suspect although I am pretty sure the DCHA does not heat the fuel.. Anyone any thoughts on this? below a pic of my fusebox and the layout in the lid. |

That's the one reading CD11/L P on the "lid layout" and named: 15 internal (diesel) on the manual list. :confused: not very clear ..
Anyway that fuse looks fine.. Must look elsewhere I guess |

Did you chase the wiring from the butt harness connector under the car [see 8.5.12 C330 HARNESS CONNECTOR (DCHA)] making sure it hasn't burnt on the exhaust or chafed on metal ? Its a 6 pin connector but only 3 pins are used. Ditto pis 5 & 6. :
Attachment 2408 Pin 2 is the SCI which should go to the IPM Fuse #15, for the diags see page 499. |
Yep followed that bunch of wires and fiddled with the connector.. all looked good to me but didn't have time to thorough check that out.
The DCHA is not enourmous important to me, but it would be nice to get it running again so I think I try to check those wires next week when my car is in the garage getting a new crankshaft seal. In the meantime I gather as much tips and info as I can to know in advance what I can check :) Edit, I walked through most diagnostics in the manual and there's tons of tests, almost everyone resulting in the conclusion "replace DCHA" .. I found one thing I can try.. removing the nr 15 fuse with engine running.. Ill try that one tomorrow |
