Enes : Hello and welcome to our web page here my name isXXXXX a Certified Volvo Car Expert Mechanic.I'm going to try today to answer your question.
Enes : checking codes without scanner on p2 volvosif u want to know if there is any codes stored in any module on your p2 Volvo follow these steps 1. turn on car and close doors and clear info display of any messages by pressing read button 2. with ur foot on the brake pedal hold down the read button and hit the rear fog lamp button twice. now your car info display will read checking dtcs in vehicle and you can scroll through each module by hitting the read button until u go through every module. this method will only tell you if there is a code stored and will not give you a specific code.
