Volvo radio doesn't accept its own code

Year of vehicle may help you get an answer as there were many radio changes. Mine has BlueTooth and many don't etc etc etc.
Why not pop into your Volvo Dealership for help.

i think this is located in the user manual for the radio IF there is one, otherwise you can search for one on google

In the owners maunel you should have a card with the radio code on it.

The radio will only display EEE or OFF when the wrong code has been entered and the radio is locked depending on model - this is due to the battery being disconnected and the incorrect radio code being entered 3 times. You will neet to reset the radio. To do this the radio has to be on for either 2 or 4 hours - see the manual for your model. If you got the code from a card from Volvo, and it didn't work, then the radio has been changed or it has been reset by the dealer and your current code is invalid. You will have to pull the radio and find the serial & model number, and get Volvo to look up the code for that radio or the dealer may be able to lookup the radio code via vin# from Volvo. The dealer can reset the radio and enter a new code. When the radio is "ready" to accept an unlock code the display will say "codE". You will need this code if your battery is ever disconnected.

I have a 2007 Volvo 670. The check vehicle ecu comes on. The fault code is MID 144 PID 191 FMI 5. THe truck won't go pass 1400 rpm, the speedometer doesn't work, the cruise doesn't work, the engine break doesn't work. I have to turn the truck off going down the road at highway speed for about 10 seconds and it'll go back to normal. Can anybody help?

consulted Volvo agency and problem solved.

remove radio by pushing in the two side tabs to alow you to remove.  Call your local volvo dealer (parts dept.) with the serial # and part # off the radio.  Type in the code and volia.

i need a code for a radio v40 2001

Did you enter the code in the proper sequence? I reprogrammed mine and it took quite awhile to reset. The manual will tell you how long it takes. It works fine now. Hope this helps.

turn off radio.remove negative batterry cable remove drive belt power steering pump.set a side do not disconnect.then remove alternator and its electrical connectors then remove alternator.

I'm pretty sure that you can call any Volvo dealer and get the code...talk to the service manager.

You can pay for codes online but there is no real need to.
