Freightliner code

This is charge pressure fault code, but really MB uses its propriate codes for PLD (MR unit, mounted on engine) and VCU (FR in EU).

FR just translates propriate MB codes to SAE standard, so to understand what is wrong u need DDDL ore Star Diagnose. Becouse this code may be becouse of blocked muffler, DPF, stuck VNT, faulty charger lines, bad turbo....

 

I agree with Pablo, your dash is only showing the PID/SID, which is the J1587 fault. SID 155 is generally a data link fault, which could be many things. You really need DDDL to get the SPN (J1939) fault to narrow it down.

For SID 155 FMI 14, I get any of these as a possible cause:

Fuel Pressure Too High/Too Low
Smart Remote Actuator 2; No Failsafe Mode; Motor Off
Rail Pressure Governor; Valve Stays Open
Rail Pressure Governor; Leakage in High Pressure Too High
Rail Pressure Governor Sensor; Signal Drift
Rail Pressure Governor Sensor; Sensor Supply Line Broken
High Pressure Pump; Leakage or TDC Position Wrong
Smart Remote Actuator 2; Temperature Warning
MCM Fault Codes Unavailable via J1939 and J1587

Let me disagree. I think it is pre MCM engine, it is PLD View attachment ADM3-manual-rev901.pdf

MBE900 is really OM904/906/924/926 engine. MBE4000 is OM457 ore OM460. It is pushrod design engine with PLD injection (pumpe linie duse - pump line nozzle, ore electronic unit pump).

Engine ECM - VCU is really MB ADM unit.

Plz read PDF attached.

 

From MB Manual - J1708 only partly implemented

 

Here in the states, every Mercedes EPA07 I've worked on was DDEC VI. May be different in other parts of the world though.

The code descriptions I posted are all of the SID 155 FMI 14 for a 2007 Meredes with DDEC VI electronics. 90% of the time when I see an SID 155 code on these, it's a problem with communications between 2 multiplexed devices. Either a bad multiplexed component or switch sending a false signal.

 

MCM is controlled with the same ADM, so code implementation is not correct too.

Anyway, u need DDDL8 ore Star Diagnose with new version of DAS
