Hello to each other, last year I completely renewed my brakes at the rear, because the brake piston was hanging on one side. I installed completely new brake calipers, so all parts of the electric parking brake were also renewed. Now I wanted to pull the fuse of the parking heater last week to learn the remote control. Unfortunately it was not possible to access the fuses with tools, because the fuse box is nested and I can not get the upper fuses out. The manual also only reveals where the fuses are sitting but not how to get there. At such moments I really wish my V70 II (the last car developed by Volvo) back, because half of the components that come from Ford were of poor quality. Anyway, I just stuck off the battery and was able to easily learn the heater remote control. I only stuck off the battery for about 5 seconds, so that both the time and time of the car can be used. Since then I have had the problem that the electric parking brake should be maintained again and again. Sometimes the symbol of the parking brake flashes and goes away only after a new engine start. I have to say that I use the brake only very rarely, because I drive the automatic and “P” completely sufficient. The mentioned messages are therefore not related to the use of the parking brake. . The brake itself works perfectly, I tested it many times and also started different programs with VIDA, all without any problems. Once again, the battery has not improved. When reading out, I only got the error message that the electric motors were left and right not contactable. That it really is due to the motors is unlikely, since both are affected. I would guess that the ECU somehow It was only since then that the fault occurred and it was also very sporadic and usually disappeared again after a few seconds. Maybe someone had the problem before or has a tip what I can still do? Terminal again with the battery and run the programs in Vida as well as press the parking brake I did everything I could think of in terms of possibilities.
