    Hi All,

    I'm hoping that I'm not the only control freak (according to my wife anyway!!) out in the motorhome world that would like to know when the ECU initiates a DPF regeneration / burn routine.

    I'm running the Torque app, with OBD2 Wifi adapter, but the only available control panel values aren't really of any help. It can monitor the EGR position, but the other important values I need are Throttle plate, Cat or DPF temp and the Torque app doesn't have these available with this van.

    Has anyone else managed to infer when a regeneration of the DPF filter is happening?

    Does anyone know of another hardware / software package that will be able to read the signals I need?

    The reason for wanting to see what's going on with the DPF regenerations is so I can prevent aborted sequences by continuing to drive until it's completed.

    I can do this with my Shogun with no problem as I'm able to read more values that are of use.

    Thanks very much for any help you guys can give.

    not technical myself but I think the engine cooling fan always cuts in when regeneration is happening.

    I've got a new reader coming tomorrow that uses wifi and an iPhone app
    I've paid for the full version so I'll see what sensors it can report on

    Thanks. As stated I'm running Torque on android so the iphone app might report on more.

    Yes I am

    Until I can connect to the new device it won't list all the sensors

    Can you give me a rough idea what roads you frequent so i can hopefully avoid them:doh::doh:
    because to be of any use you must be observing this data whilst driving:Eeek:
    Talk about OCD
    Don't take it too personally, whoever does this needs a rethink

    The problem with OBDII diagnostics is that most readers can read the generic DTC codes but not the manufacturer specific DTC's unless you buy a brand specific diagnostic tool, eg SDD/ IDS VCM for Ford, Mazda, Jaguar and Landrover. Another option is Autologic but that is a bit expensive for the DIYer, my one cost a lot but can force a DPF regen on most manufacturer brand Euro 5 power control modules. Autel do some brand specific readers for about £150, I carry an Autel unit in the MoHo as it also has SRS and ABS functionality along with Fiat specific enhanced DTC's, though it does not give the option to monitor the DPF regen cycle. Below is a post I did on a Landrover forum to explain Diagnostic Trouble Codes, DTC.



    Thought I would try and explain the differences in DTC codes. So here goes:

    There are basically two types of DTC codes for OBDII Diagnostics:

    Emissions related DTC's, Tested DTC's
    Type A

    1. Emissions related.
    2. The Malfunction Indicator Lamp (MIL) will be illuminated as soon as the error occurs.
    3. Stores a freeze frame DTC after one failed driving cycle.( history DTC is stored )

    Type B

    1. Emissions related.
    2. Sets a Pending Trouble Code after one failed driving cycle.
    3. Clears a Pending Trouble Code after one successful driving cycle.
    4. Turns on the MIL after two/three consecutive failed driving cycles.
    5. Stores a Pending Trouble Code as a DTC after two consecutive failed driving cycles.

    Conditions for Clearing the MIL/DTC – Type A or Type B

    The MIL will turn off after four consecutive driving cycles in which the diagnostic runs without a fault.
    A history DTC will clear after 40 consecutive warm up cycles without a fault.
    DTC(s) can be cleared by using a scan/diagnostic tool.

    Non–Emissions Related DTCs, Un Tested DTC's

    Action Taken When the DTC Sets

    1. The Malfunction Indicator Lamp (MIL) will not illuminate.
    2. The ECM will record a DTC at the time the diagnostic fails.

    Conditions for Clearing the DTC

    A history DTC will clear after 40 consecutive warm up cycles without a fault.
    DTC(s) can be cleared by using a scan/diagnostic tool.

    How to read a DTC Code

    The DTC value will help you narrow down the specific component or module in question. A DTC has a standardized format that can be interpreted as follows:
    The first part of the DTC is the Alpha Designator. The alpha designator will be:

    B - Body electronics (i.e., door and hood latches)
    C - Chassis (i.e., traction control or ABS)
    P - Powertrain (i.e., engine, transmission)
    U - Network communications for the different control modules

    Second Digit - Code Type
    The second digit identifies whether the code is a generic code (same on all OBD-II equpped vehicles), or a manufacturer specific code.

    0 = Generic (The diagnostic codes that are required by law on all OBD II systems are "generic" in the sense that all vehicle manufacturers use the same common code list and the same 16-pin diagnostic connector. Thus, a P0301 misfire code on a Ford means the same thing on a Vauxhall, Citroen, Toyota or Mercedes.)

    1 = Enhanced ( Each vehicle manufacturers also have the freedom to add their own "enhanced" codes to provide even more detailed information about various faults. Enhanced codes also cover non-emission related failures that occur outside the engine control system. These include ABS codes, HVAC codes, airbag codes and other body and electrical codes.)

    Third Digit - Sub-System

    The third digit denotes the type of sub-system that pertains to the code

    1 = Emission Management (Fuel or Air)
    2 = Injector Circuit (Fuel or Air)
    3 = Ignition or Misfire
    4 = Emission Control
    5 = Vehicle Speed & Idle Control
    6 = Computer & Output Circuit
    7 = Transmission
    8 = Transmission
    9 = SAE Reserved
    0 = SAE Reserved

    Fourth and Fifth Digits
    These digits, along with the others, are variable, and relate to a particular problem code error number

    So let's diagnose a DTC, I've picked P0404-73 EGR control circuit range/performance: actuator stuck closed

    so we have:
    P = Powertrain (engine, transmission)
    0 = Generic
    4 = Emissions control
    0 4 =This is the specific error code within Emission control. In this case the EGR control circuit range/performance
    -73= This is a specific problem, in this case the actuator is stuck closed. 72 means its stuck open.

    Lorryman100 - Thanks for the detailed post.

    My Mitsubishi appears to have far more data values available than Fiat are making available, I thought they would have all made the same common values available but clearly not.
