V70: Electrical Resetting Parking Brake/VIDA

[morsing]

Hi all,

I've had a bit of a saga trying to replace rear brake pads on a '15 V70. To make a long story short, I couldn't get VIDA to retract the parking brake so had to do it manually.

An AA mechanic then did something with an iPad like device, and I then replaced the broken actuator.

The problem now is that the PBM says the angle sensor needs calibrating or maybe it's a different problem, not sure, but the parking brakes are clearly in some wort of service mode.

The "Activations" tab in VIDA for the PBM is greyed out. There is another place I can set the parking brake to service (the button with the "2000" module), but that does nothing

How can I get VIDA to reset or calibrate the system? Or by any other way?

Would the 2 brake modules (either side) have to be wound back to cause the pair to be in fault condition to be calibrated?

Or with them just being 12v motors, application of 12v to the motor to wind the actuator onto the pads?

Sometimes these cars are too clever for their own good.

Multiplexed systems can sometimes throw up fault reports which refer to the wrong system but surely the angle sensor is the sensor which tells the ECU in which direction the front wheels are steering and doesn't have any connection with braking functions.

It's not according to VIDA, but still doesn't help me get the brakes working.

My wife has just returned from a first attempted drive and it started saying "parking brake not fully released" even though it is.

I really don't want to pay Volvo 300gbp to press a button...

Gareth!

Possibly! Kinda rhymes with the message about them ot being fully retracted.

Yup, might try that this weekend.

Looks like the car is ready for the scrap. Independent Volvo garage says they can't reset parking brakes...

[Tatsfield]

Sorry to ask but your posting is slightly ambiguous. Do you mean that they failed to reset your brakes or that they are not able to reset any parking brakes. And what does "reset" mean? Does it mean simply winding them out and then when finished working on them winding them back in? As monkeh says, a lot of owners have posted that they just put a 12 volt battery across the brake terminals and powered the motors directly.

On my daughter’s XC70 when I renewed the rear brake pads I used the 9volt battery method to wind each of the handbrakes back, then again to wind them back in. All worked well and no messages generated.
Our main dealer renewed the rear pads again earlier this year. We had them do it as they were replacing the rear brake discs, rear springs and trailing arm bushes.
In your first post you state that you had to retract the parking brake manually. What method did you use?
You state that you replaced the broken actuator. Do you mean the motor which moves the brake on and off and what was the fault with it?
It seems strange that a so called Volvo specialist cannot reset a parking brake.
I understand that there is also a Parking Brake Module ( or Brake Module) somewhere but I have no knowledge about it.
I agree with Tatsfield that the angle sensor is a separate issue and not connected with the parking brake issue.

I never reset my electric parking brakes through VIDA - I have followed VolvoSweden's "how to" on YouTube for the last three years and it always works perfectly. You just remove the electric actuator on each calliper, wind the actuator back in using an allen key in a ratchet, refit and then follow the instructions to get the actuator to reset. It works perfectly.

Or is a 2015's setup different?

I can imagine the conversation now Henrik, "Sorry, as an independent volvo surgeon, I can't do a parking brake"

Have you checked volvosweden's channel on the youtube?

Beat me to it!
