Reprogram/Replace ECM/PCM for my 2005 Volvo S40

My 2005 Volvo S40 had front crash/ accident couple of weeks ago. When I put the key in the ignition, it just turn on with all the lights on dash board, but it won't start. I plug in the computer because it has check engine light, then it reads....two codes, P0603 and U0101. Someone told me I need to reprogram or replace the ECM in the car. Please any advice or suggestions? Thanks

The best thing is to go to your local Volvo maintenance shop or Volvo experts to find out whats the problem..usually the coomon ones I think is the programs inside its ECU unit..you try this..ask the volvo experts to reset the ECU and lets see..if problem arise then it is no doubt you might need the sensor..hope this help..

SOURCE: The Volvo S40, 2,4i, 2007, fuel cut off switch

look in the trunk... either it has side panels that can be removed... or you will see a hole in the side of the lining with a sticker that points out where it is.

SOURCE: Car won't start

Your immobilizer is enabled. Try locking/unlocking the doors with the remote five (5) times, this should remedy.

If there is a blinking car icon with an "X" over it. This icon means the Immobilizer has been activated and hence won't allow the car to start. It could be due to a bad SCU, Start Control Unit. The SCU is actually the ignition switch on these cars.
Most of the time it's triggered by the anti-theft system..You can try this trick i learned that the dealers won't tell you...try locking and unlocking of the doors five times with the remote to reset the immobilizer and see if this helps.
Good luck...i hope this helps...please take a minute to rate me a fixya.

SOURCE: Check engine light is on. OBD reads p0191 &

Replacement of the fuel pump would be the case here,unless the fuel filter needs to be changed.To find out,remove the fuel filter,and blow threw it with your mouth,kinda tast bad but it will tell you if the fuel filter is restricted.You should be able to blow threw it easy.

2005 Volvo S40 with key stuck in ignition. It turns off but key doesn't come, out of the steering wheel. Please advise needed, if lock change is required estimated cost of part and labour please.


Some ignition system locks will not release the key unless you push in towards the column while turning further off. It is a safety device to stop in advertent removal of the key while moving. Try that first.

If I replaced the PCM on the 2005 dodge ram truck would I have to reprogram the keys to make the truck run?


If you key has a chip in it, you will probably have to get your ECM reprogrammed with the proper VIN, since it no longer matches the original VIN on your Vehicle. I don't think the dealer would program your keys to a mismatched VIN number, so more than likely you will need your ECM reprogrammed with the proper VIN. This will need to be taken to the Dodge Dealership to be fixed.

What is solution for key error msg on 2004 s40?


The system should be scanned with Volvos' Vida. However, the most common problem is usually the antenna ring that is mounted around the ignition lock (where you put the key in). You should also try another key if you have one. Sometimes the key can be the problem

2005 Volvo S40 won't start


Check battery voltage while trying to start car.  May need new battery.  Since you just bought the car the battery may be weak from sitting at a car lot for a while.
