Air bleeding from the ABS/ESP system hydraulic circuit

The procedure must be performed with the engine stopped and the key turned to running (Key ON).
Get connected to the diagnosis take-off located in the cabin, on the passenger's side, by means of a suitable instrument. Follow
the "BLEEDING" procedure described by the instrument.
NOTE Press the brake pedal over and over again during the process.
The correct blow-off sequence for the four wheels is as follows:
- rear left wheel (RL)
- front left wheel (FL)
- front right wheel (FR)
- rear right wheel (RR)
As regards the systems of the ABS 8/ESP 8 type, no other sequence is permitted. As far as ABS 5.3 systems are
concerned, on the contrary, you may act on the single wheels without having to perform the entire procedure.
After every single wheel has been bled, visually inspect the brake fluid level and top up, if necessary. Do not fill with
fluid that has already been used.
In the event that either one single phase or the entire blow-off process is repeated, you will have to wait at least 5
minutes in order to let the system solenoid valve cool. Otherwise, the valves themselves may be damaged due to
overheating.
Prior to tightening the drain screws, make sure that the corresponding routine has been completed, and the brake
fluid flows out smoothly (no air bubbles should appear).
In order to ensure correct bleeding, the vehicle is to be set in a proper way. You will have to clean the drain screws and procure
a transparent tube and a container partially filled with brake fluid, to be connected to the screw of the wheel being bled.
