thanx and bye

 

Here is a master list of Volvo DTC's...

The codes you mentioned are no where to be found. How did you get them? If you get the codes read via OBD II at any indie mechanic or autozone (usually free) with a generic reader we can probably get you going in the right direction or if you go to Volvo they will read the DCT code and and tell you what's wrong and charge you for it.

 

i actually am a auto tech , and i get those codes with my scan tool , those are specific volvo codes but i dont have the definition thanx a lot

 

Got it for you. But I can't find anything regarding the A11A code.

*Diagnostic trouble code (DTC) information ECM-250A

Condition

The engine control module (ECM) receives information from the heated oxygen sensor (HO2S) about the fuel/air mixture at different loads. The diagnostic trouble code (DTC) is stored if the engine control module (ECM) registers that the fuel/air mixture deviates too much from target lambda value, leaving the long-term trim in one of its limit positions.


Substitute value
-None.


Possible source

Upper limit
-Air leaks in the induction system.
-Air leakage in the exhaust system.
-Low fuel pressure
-Damaged mass air flow (MAF) sensor
Lower limit
-Oil level too high.
-Contaminated engine oil
-Leaking injectors
-Damaged EVAP valve.
-High fuel pressure
-Damaged mass air flow (MAF) sensor


Fault symptom[s]
-Deterioration in performance
-High fuel consumption.



*Diagnostic trouble code (DTC) information ECM-A10B

Condition

The engine control module (ECM) communicates with the alternator control module (ACM) via a standardized serial communication method, Local Interconnect Network (LIN).
The diagnostic trouble code (DTC) is stored if the engine control module (ECM) detects interference in communication with the alternator control module (ACM).
The diagnostic trouble code (DTC) can be diagnosed when the ignition is switched on.


Substitute value
-The alternator control module (ACM) charges at a fixed voltage of 13.8 V.


Possible source

-Contact resistance and oxidation in the terminals
-Short-circuit between the LIN wiring
-Open-circuit in the LIN wiring
-Internal fault in another control module in the same part of the LIN network
-Damaged alternator control module (ACM)
-Generator with a charge regulator not intended for LIN communication installed.


Fault symptom[s]
-The "Generator not charging" warning lamp is lit when the engine is running.

 

thanx a lot for helping me ! i know it is hard to find those codes and you did it thanks again , hey do you think it is possible for you to tell me where did you get that info ?
thanx anyway

 

No problem man.

I asked around and a guy from another forum sent me this. I'm assuming it's from either VADIS of VIDA or possably any other DVD based manual that a repair shop would have.

You can pick up a copy of VIDA or VADIS on Ebay for pretty cheap but I'm not sure how legit they are. I've heard they work but I've also heard they're boot leg copys. It's too much money for me to test it out. But if you got the extra cash laying around, it might be worth it for you.
