1997 freightliner classic dies

Deleted my post, Lol. Any other use of the word on ttr is frowned upon. Lol

 

16 is coolant level code. Maybe plug the temp sensor in and start it up and after it dies run codes again. According to those codes, I’d unplug the coolant sensor, after plugging the temp sensor back in. See if it runs. Might need to jump the plug on coolant sensor. I don’t think so. Normally Yellow light will stay on with it unplugged while running. Paperclip turns light off.

 

If that 36 was the first yellow flashed, that will be the most recent fault, besides the CLS fault. Oil pressure fault IIRC.

Do as

 

But you have no reference as to when they were logged. Check oil pressure sensor first. Did you look into that fan solenoid?

 

25 is “no codes” Right now you have no codes. The red are active. The yellow are old stored codes. Right now they mean nothing. Put everything where it belongs, start it up, see what happens. Check codes again if it shuts down. Get the active red code and any new yellow code. New Yellow code ( if any) will tell you if there’s an intermittent problem.

 

Have you ever checked the grounds for the ecm at the frame near battery box? How about the power for ecm from the battery, along with the small inline fuse. Corrosion can cause havoc.
