What does ACM stand for on a Freightliner Cascadia?
Freightliner Aftertreatment Control Modules (ACM)
What is SCR catalyst conversion efficiency?
This measurement happens between your inlet and outlet NOx sensors and it’s called your SCR NOx efficiency. If the SCR NOx efficiency goes below 70%, then these fault codes get set “Active.” The only way you can clear these codes is by doing a forced regen with the SCR NOx efficiency above 70%.
What is a NOx conversion test?
– A NOx Conversion should be run to check NOx sensor signal and function for any of the above codes. A NOx conversion test only checks NOx sensor function. The test compares the. NOTE: readings of the two sensors as the engine cycles through multiple conditions to confirm they.
Where is the ACM on a Cascadia?
Its in between left side front fender and battery box. Fairly easy to find . Unless its GHG17 than it may be on right side behind Aftertreatment filter.
How is SCR efficiency calculated?
Therefore, SCR conversion efficiency is calculated as 0.9×0.3+0.6×0.7=0.69 in the condition that the temperature of the SCR 10 is 225° C., which is the activation temperature, the loading amount of a NH3 is 1% (1000 mg), and the reference control signal of the dosing module 20 is 30%.
How long does a NOx sensor last?
between 50,000 and 60,000 miles
In addition to high heat, the sensor can be affected by other things, including contaminants in the exhaust, excessive amounts of unburned fuel in the system and more. Generally speaking, your oxygen sensor should last somewhere between 50,000 and 60,000 miles.
Where is the ACM on a Freightliner Cascadia?
I am having a tough time trying to locate the ACM on a cascadia,can anyone please ponit me in the right dirrection.Pictures will be great. The ACM looks just like the MCM and will be located near the emission control equipment on the frame rail or a mounting bracket.

Where is the fuel tank on a Freightliner Cascadia?
Its behind front drive side wheel plastic fender in between fuel tank . go underneath and check in between front wheel and tank. If I helped you in anyway, then please press Thanks. Just like torqueman said well kind of. Its in between left side front fender and battery box.
