The CCM rotors and pads on the Giulia QV can cost upwards of $15,000.00 when time to replace. I track Giulia, and since I don't have THAT kind of disposable cash, I decided to replace (preserve) my CCM brakes by installing the Girodisc replacements ( www.girodisc.c... ).
Well, I didn't follow proper procedure for replacing pads/rotors and ended the job with a Bazillion errors message. Here's why:
Without first disconnecting the negative lead, when pushing back the pistons to install newer (thicker) pads, the car will see excessive fluid flow (reseating the pistons/pads) and assume a leak, thus closing the leaking circuits to prevent total-fluid-loss (only two calipers work in this failsafe mode). This causes errors for apparent dependency systems as well.
* To recover from this, use MultiECUscan ( www.multiecusc... ) to connect to the ABS system and clear the codes. This is what I'm showing you how to do in this video.
* To prevent these errors from ever happening during a pad/rotor change (seems to have worked consistently)
-- disconnect the negative battery terminal.
-- perform the pad/rotor service.
-- pump brake pedal to reseat pads/pistons
-- reconnect negative battery terminal
-- perform procedure to clear codes caused by battery disconnect
