My Giulia is old enough that it is time to change the brake fluid. The procedure for bleeding the brakes looks to fairly standard EXCEPT for that the procedure calls for using a scan tool to check "volumes" via the Data Link Connector. Are there any Professionals out there that can tell me more about this? Can a home mechanic still bleed the brakes himself, or is it now necessary to have a shop hook up special diagnostic tools to do it?

From the AR Giulia Tech Authority:
  • If no components were replaced and the system was not opened, with the scan tool connected to the vehicle Data Link Connector, go to ABS control unit in the "Miscellaneous functions" menu and select:
    • Check Air Presents in ABS Module.
    • Check air in the hydraulic circuit between IBS control module and calipers. Refer to following chart for parameters.
  • Check that the value of Front Left (FL) - Front Right (FR) - Right Rear (RR) - Right Left (RL) volumes shown on the diagnostic equipment are within the ranges shown in the table.

The main issue is making sure the ABS distribution block and pressure reservoir get bled. There's also no mechanical connection between the brake pedal and the brake fluid.

bleeding the brakes requires to put the rear brakes in service mode (can be done in the infotainment), and requires a motive powerbleeder tool with the european attachment set at 30psi. I've done it on my Q4 with no issues

This was posted on a different forum:
"Put the car in brake service mode in the infotainment system. Disconnect the integrated battery sensor (IBS) then remove the negative battery connection. Then service the brakes. Reconnect the negative battery cable and then the IBS. Turn on the car, don't start it, remove brake service mode, start the car, turn the steering wheel full left and then full right, recenter the wheel, turn the car off and you should be good to go. "

This is the factory procedure, hope it helps:

I also have the service CD from MOPAR Tech Authority, and the procedure for the Giulia and the Quad are the same. The procedure looks straight forward except for the ABS scan tool measuring volumes. Are you saying that you did the bleed but not the scan of the volumes and everything was OK?

Mike, good to know about multiecuscan. Reminds me of the laptop connector cable and software that I had to purchase in order to work on my Evinrude outboard. And the oil change service interval reset is another one that has eluded me no matter what procedure I use. It is apparently a problem for the Dealer, too, since they did not reset it after their first free service.

correct, I did the bleed without the scan.

There is a program called multiecuscan which allows you to perform the operation with the proper adapter cables. I use it to reset the service interval during an oil change
Mike, I can get the MultiECUScan Interface Tool Kit with adapters for $112 from Alfissimo. But re. the software, did you find the Free version satisfactory for the home DIYer or did you pay for the Registered version?

you have to get a registered version, the free version is very limited. There are also ebay sellers in the UK which I have bought the adapters and elm327 usb from for much cheaper. I use an older spare laptop

BTW, I like your take on the transmission unlock tool. I am going to make my own, thanks for the idea!
