Sep 3, 2. It means that the engine ECU has a code in it. ECU only identifies the module, it is not a fault code. Can you hit a dash button and get more numbers?

Different trucks display faults in different ways. Post exactly what is says. GrapeApeSep 3, Oldironfan Thanks this.

Sep 3, 3. I forget exactly the way to do it, sometimes you have to hold down the buttons and for another step you have to just press. Play around with it for a bit and you should be able to get them to come up. Sep 3, 4. I have been getting that code for years it comes and goes,I just ignore it.

With these new emissions trucks the sensors will set off false warnings. Sometimes even your check engine light and emissons light will come on,And when you take it to the dealer its off and guess what they cant find nothing wrong. Sep 8, 5.Log in or Sign up. Find Trucking Jobs. Oct 20, 1.

I have a Volvo with Detroit Diesel series 60, 14 liter almost identical to a Now can not get it to start or run on it's own. Will start and run on either. I get a check engine light, run dianogists and get a code 21 active and code 51,52 inactive. Also changed the Timing REference sensor also known as the cam position senson. Replaced both these after getting the code and not starting with new sensors and still getting the same codes and not firing on it's own.

All I can think of at this point is to check the harness, though it looks in good shape. Please any suggestions is appreciated as I have so much time and money into this engine and got to get back to making so money with it.

The gears in it are often plastic- they crack and crumble when they get old. Is your electrical system letting you down? Bad battery, or shorted battery, corroded grounds- is the ecm wire corroded where it's mounted on the positive terminal on the battery? Are the connections on the ecm loose, or corroded?

How Do You Get Freightliner Codes?

Is the fuse for the ecm blown out? Is the drain valve open on the water separator? If this is the first startup after the rebuild, are the fuel lines connected backwards on the transfer pump? Good luck- hope it's an easy fix. Oct 20, 3. Flightline Thanks this.On-highway truck drivers demanded more of their on-highway truck. They wanted options.

Optional headway control in a new interactive dash display allows for adjusting following distances.Freightliner codes are obtained through diesel engine parts sites, such as DieselServiceParts. The site provides a long listing of codes that enable truckers and mechanics to diagnose a specific engine problem.

The engine control module, or ECM, constantly tracks voltage signals and records codes when values do not meet with the standard set for a specific system or part. Freightliner codes are categorized as inactive or active. If an error occurs but does not take place during diagnostic testing, it is referred to as an inactive fault. However, if the error occurs when a diagnosis is being made, it is considered an active fault. The status of a code is determined by an electronic service tool or by flash code activity.

The intake manifold pressure sensor circuit is designated by two codes, andand the coolant temperature sensor circuit has a error code.

In addition to fault codes, diesel parts sites can provide engine specs and torque specs. Common failures occur the most often in sensors, fuel pumps and parts connected to the exhaust system in trucks. Home World View. What Causes a Diesel Engine to Overheat?By peterabbeMay 1, in Engines.

I called the Allison dealer that installed the new ECU for the trans. By the way, the coach drives just fine, but has "service" illuminated on shift pad. Any help would be appreciated, thanks. Freightliner Thanks for the welcome.

I should probabley call Sparton, they made the coach. The Allison dealer also Sparton Rep. Yes, if on Spartan chassis, not Freightliner, call them: Not fun when the tps goes out, had that happen in the early 90's.

Still drove, but I had to keep moving the accelerator back and forth to keep it going. Use full throttle default, DNA. The sensor the ECM is looking for is a potentiometer, basically a pot. ECM not reading any voltage - so you might have an open 5 volt supply to the Pot, loose connector, broken part. In this case, my thought is a dirty control.

That pot is part of the throttle control!

NOTE: A good throttle position sensor should have resistance of: 1. If the original ECU now works, inspect the ECU connectors for any corrosion or damage which may cause an intermittent condition.

If the original problem reoccurs, reinstall the replacement ECU.
