New Problems

[markh29]

Hi

I have now had the DPF replaced after alot of messing about, the garage took it to be reset blah blah and now i have more fault codes
Hopefully someone here can help me with them? they are

ECM-0183 Fuel Temperature sensor .Signal too high
ECM-C301 Control Module, faulty software checksum ECM
ECM- 2584 Additive dosing module (ADM)
ECM- 2585 Additive dosing module (ADM)

Im getting really stuck now! The fluid was topped up aswell

Cheers

i found something for one of the codes that you get

it looks like you will need volvo for ECM-C301

ECM-C301


*** "Internal Control Module Software Incompatibility, D4204T" ***

Condition:

The control modules communicate with each other for exchange of information in a network via a standardised serial communication procedure - CAN (Controller Area Network). The Central electronic module (CEM) regularly transmits messages on the CAN network. These messages contain information about which signal configuration ID applies to the vehicle. The control modules on the CAN network have the same signal configuration ID so that they can communicate with each other.
The control module compares its configuration ID with the signal configuration transmitted on the control area network (CAN) by the central electronic module (CEM).
The diagnostic trouble code (DTC) is stored if the control module detects that:

* The control module's configuration ID differ from the ID that the Central electronic module (CEM) transmits.

The control module's test for the diagnostic trouble code (DTC) starts in the event of:

* Ignition switch position II.
* Starting the control module's CAN communication.

Note! The control module can only detect the fault once the test has been started and the diagnostic trouble code (DTC) is stored when the conditions are met.


Substitute Value:

* Control module shuts itself off ("bus-off").

Note! When the diagnostic trouble code (DTC) is stored, the control module responds to the diagnostic commands.


Possible Source:

* Incorrect configuration ID (the control module is not intended for this vehicle, for example it is a used control module with different software/hardware).

* Open-circuit in the CAN cables between the control module and the Central Electronic Module (CEM).


Fault symptom[s]:

* None

-------------------------------------------

*** "Faulty Configuration" ***

General information:
The diagnostic trouble code (DTC) is stored when the communication between the central electronic module (CEM) and the relevant control module has been interrupted. There can be a number of causes for interruptions in the communication:

* Faulty signal configuration in the control module that stored the diagnostic trouble code (DTC). The fault can be due to a customer or workshop replacing a control module without downloading new software for the replacement

* Intermittent open-circuit in one or both CAN cables in part of the network

* Intermittent short-circuits between the CAN cables

* Intermittent short-circuits between one of the CAN cables and ground or supply voltage

* Internal fault in the control module that stored the diagnostic trouble code (DTC).

The fault can also be due to faulty software in a control module, a hardware problem in the CAN network (faulty cables) or a fault in a control module.

Note! If there is a diagnostic trouble code (DTC) for a communication fault in a control module, check whether diagnostic trouble codes (DTCs) have been stored in the central electronic module (CEM). The central electronic module (CEM) monitors the voltage level in the CAN cables and is the only control module that can directly store a diagnostic trouble code (DTC) for a short-circuit in one of the cables for ground or supply voltage. Do not replace the central electronic module (CEM) in the event of a CAN fault unless fault-tracing has indicated that the central electronic module (CEM) has an internal fault.[/B]

Corrective Actions:
1. If this diagnostic trouble code (DTC) is the only communication diagnostic trouble code (DTC) stored in one of the control modules in the high speed network, try to remedy the fault by downloading new software for the control module that stored the diagnostic trouble code (DTC)

2. Check the cables in the CAN network according to the following fault-tracing

3. The control module should be replaced as a last resort.


Other Information:
To download software to the relevant control module, see Replacement parts catalogue/Software index or the Software manager.

Cheers Askim, its strange given that its not had any modules changed and the code wasnt always there

Its booked in to a Volvo Specialist next Tuesday 45 quid plus VAT for them to read the codes again!
I guess i will have to see what happens

Cheers

could be only a corrupted software in this new machine can happen

[markh29]

The Fuel Temp one relates to Circuit A apparently if that helps at all

Cheers

All fixed now, took it to Volvo Specialist in Wirral and they were excellent

Software updates were needed, the ecu wouldntbtake the update though, other modules did. No more dash light and they told me not to panic over ecu, its working normally

good enjoy your light free dash

Went into limp mode twice today! It's not set the light off on the dash though.
On my reader it says particulate filter restriction, ash accumulation! I'm really peed off.
The dpf is brand new, the dpf sensor is brand new, the fluid is 13/15 full so why is it reading this

Mark

did you change as well the pressure sensor?


as it could be the culprit of the problem.

[markh29]

yes pressure sensor was changed, the machine is now showing high back pressure on the dpf apparently, the dpf is brand new
