Codes that run both fans..
I was wondering, what trouble codes, make both of your fans run at all times?
This is just another one of my problems, from another topic that I posted...(can't communicate with pcm) I have an obd1, 94'z 383-LT1, A4 swapped to an M6. |
It's most of them. There are probably few that don't. I don't have a list.

Lol, ah no way. Thats not the answer I was hopin' for...I guess I'll start with my wiring problem first, then I'll deal with the SES light/both cooling fan problem.
Thanks Rob! :) |
thought I would bring this back to life because I have the same problem on my 94 z28.I did have mine scanned today and it's showing Torque converter quad drive module and something like EGR quad drive.

Codes are essential, particularly when the 94 does not have quad driver modules. 93 was the last year for that. That's the problem with using a "generic" code list, or relying on the generic code display that is provided by some scanners.

It will set codes if the EVAP and EGR solenoids and AIR pump are not connected (with a faulty fuse in the AIR circuit). Using the incorrect code list, those will show up as "quad driver" problems. Swapping to the M6 means the PCM is still looking for the 4L60E electronic control interfaces inclduing the TCC lockup, and can't find them, which sets codes. Common code in a 94 is DTC 29 for the AIR pump. That definitely turns on both fans. The cure is to put a good fuse in the AIR circuit, even if the pump is disconnected.
For the exact determination of the meaning of the codes, you need an LT1-specific code list. Shoebox has one on his website. http://shbox.com/1/Dtcs.htm I'm guessing you got DTC 26 and DTC 27. Look at the right side column for the 1993 code description, and you will see references to the quad-driver modules. But you have to use the left hand side of the page, for the 94/95. |
