Cat trouble codes

Do you know what the 12 fault code is or know where I can find what the fault codes mean? I have found several but none that just list one particular code. I would appreciate it.

 

Code 12 is the coolant level sensor fault. Could be that the coolant is low or the sensor is needing cleaned/replaced. If you have a CAT operation manual the codes will be listed in there.

 

i have a 2004 mbn. just put ecm off a 2000 model with serial# 6nz27647. tach wont work, engine fan wont turn on and cruise control switch is backwards. what do i need to do?

 

Hey underpsi, please send me that link

 

What was used to get the fault codes?
Are any of them active?

The reason I ask is the codes are all over the place, assuming they are PID-FMI

179-2 is Rear axle weight Data interm. or Incorrect
175-5 is Oil Temp open circuit
135-12 Extended Fuel Pressure Bad Device or Component
32-00 Transmission Splitter Position out of range
192-0 Bad message

I would concentrate only on active codes at this time or print then erase the codes and test drive to see what comes up.

 

OK.. How can I tell the date a message was posted on so I don't reply to old posts? I looked all over the header and all I see is Last Seen which could have been a few moments before I logged in.... Any help would be appreciated as I only visit this forum a few times a week so it is hard to track new and old posts without a date posted line.

I am probably missing something obvious

 

You are, but lots of folks do the same. It's in the upper left hand corner of each post.

 

Hey UnderPSI would you please send me that link that list the codes
