2004 Mack Granite Fault Codes

Recommended Posts

I bought another Granite at an auction,  seems to run fine but has 3 codes

2-9 (ASET CEGR) Combustion temperature sensor

3-5 Engine Brake Output #1- This wire was connected

3-6 Engine Brake Output #2 - This wire was laying on the manifold, I reinstalled it and the code did not reset and of course the engine brake does not work


Any insite where I can find the Combustion temperature sensor and how to test the engine brake?  can you just wire it up like a dynatard?
