	Risk of injury to skin or eyes from hydraulic fluid spraying out under pressure. Risk of poisoning from swallowing hydraulic fluid.	Release the pressure in the hydraulic system completely before starting any work on the system. Wear protective clothing and safety glasses.	AS00.00-Z-0013-01A
1	Loosen leaky line, center and tighten without tension to 50...55 Nm	Wait for pressure relief in ABS system. Pressure is relieved 10 minutes after engine is shut down so that the ABC high pressure line can be opened. It is only possible to ensure that the line connections are properly tightened when they are positioned tension-free with particular care (tighten nuts as far as possible without using tool) and then tighten to specified torque.

2	Check system for leakage	For this purpose: Clean leaky point. Spray line/component with leak detection spray. Connect STAR DIAGNOSIS. Select menu item "Actuation" in the ABC system and allow the vehicle to run for at least 10 min in the "Rodeo" program (whereby the system heats up to reach operating temperature). Perform visual check. If the system is still leaky: ↓ Remove/install/replace leaky lines. Check system for leakage For this purpose: Clean leaky point. Spray line/component with leak detection spray. Allow vehicle to run for at least 5 min in the "Rodeo" program. Perform visual check. If the system is still leaky: ↓ Remove/install/replace the corresponding counterpiece for the line terminal (e. g. valve block, T-piece) Check system for leakage For this purpose: Clean leaky point. Spray line/component with leak detection spray. Allow vehicle to run in the "Rodeo" program for a further 5 minutes. Perform visual check.
