Reset Your Volvo’s Computer = Big Difference

Posted on

How to do the reset? By simply starving the car’s ECU of electricity.

How to Zero out Your Volvo’s Computer and Make it Re-Learn your Driving Style

Since all 1990s and 2000s Volvos’ ECU’s haveĀ volatile memory and rely on a constant supply of 12 volts DC from the car, disconnecting the battery will do it. Follow the link below for more on this procedure.

“When my MAF sensor went bad, I changed the sensor and the car ran afterwards – but it was reaaaallllyyyy slow until the turbo picked up, and I noticed black smoke out the back. Once I reset the computer, it instantly had its pep back.”

  1. disconnected battery on a 2001 V-70 ATSR 5 cyl non turbo and lost all computers trouble codes and cannot get computer to send any codes ,

    Would not start below 30 degrees , possible ignition or fuel problem

  2. Electral issue,Volvo S80 2004,loses power to dash,AC and loses acceleration when it is hot ambient temperature outside. Will correct itself by turning off the ignition and restarting. This does not happen all the time never know when it is going to happen.There is no Volvo service center in our area. What causes this?

  3. Hi guys, was wondering if someone could help me? My wife left the lights on in the car causing the battery to go flat. After managing to jump start it I found that the trip computer in the dash wasn’t working. It no longer displays anything I.e fuel consumption or average miles etc. is there a way I can get these displays back without having to spend too much? My car is a 2005 volvo s40 diesel.

  4. After driving at highway speeds with cruise control on for about one hour the engine shut down,engine still running with no power.I have a engine code reader and it says po607 code,I erase all codes and the engine is back to normal again,should I disconnect the battery to reprogram my ECM or replace computer? 2005 xc90 t6 engine with 215000 miles. Sincerely Dan Goetz

  5. My Volvo over heated since then I can not get the motor to wind over is there any resets that I can do to get it to start the dash instruments work perfectly fine just no ignition at all

  6. I need a replacement ECU for my Volvo S80 2004 with serial number 0261204559, 01275781B. I would like to know how to go about replacing the ECU as i learnt replacement ECU’s are sourced by serial numbers. Seen a couple on Ebay but want to know which to buy.

    Thanks.

  7. Hi, I am considering purchasing a 2011 Volvo C70. The Car Fax shows several line items for “computer reprogramming”. Is this an issue or standard for Volvo? 5 in 6 years, 1 before the car even sold, oxygen sensor, than 1/2014, 3/2015, 4/2015 and 1/2016. May also have something to do with time of registration or routine service? Thank you very much for any feedback or guidance on this topic for me!
