Nagging P0573 Ailment Humbles Volvo V70 2.4T With No Cruise Control On The Open Roads
OBD2 Diagnostic Trouble Codes (DTC):
P0573 Brake Switch A Circuit High - Engine System Service Required
VIDA Diagnostic Trouble Codes (DTC):
BCM-0103 Pedal Position Sensor faulty signal
ECM-9400 Brake Pedal Sensor - Signal too high
This is my second go-around with P0573 in the V70 - hence the name 'Brakin' II'. I first encountered brake system DTC's for the V70 approximately January 2022 leading to replacement of Brake Position Sensor (aftermarket replacement), Brake Pedal Sensor (aftermarket replacement), and Brake Control Module (XemodeX rebuild) in February 2022. Everything drove perfectly before an unexpected return of the dreaded P0573 July 2022. The code cleared on my cheap Autel OBD2 unit but then returned with increasing frequency until it would simply no longer clear.
IPD provided a replacement Brake Position Sensor (aftermarket replacement) under the original unit warranty but the P0573 code remained after installation December 2022. The car drove flawlessly except the Cruise Control would not activate due to the P0573 DTC.
With an upcoming road trip planned in the V70, I decided to pursue solving the P0573 riddle hoping for a return of Cruise Control for the open highway driving anticipated on my spring 2023 road trip.
Follow along in my travails pursuing the P0573 demon deep within the 2002 Volvo V70 2.4T.
Sometimes you just have to throw-in-the-towl when a project is beyond your own limited abilities. I have been taking our V70 and XC70 to The Volvo Pro's at Dynamic Import Service since 2019:

I had replaced the brake position sensor but one of the contacts was slightly askew and not making full contact inside the connector. Dynamic replaced the aftermarket unit with Volvo OEM as well. It's been working perfect since March 2023.
