Hydraulic unit, replacing: Removal: Notes
WARNING:
Never, under any circumstances, open the ABS hydraulic modulator. Reassembling it requires special equipment and facilities.
NOTE:
An ABS modulator for ABS has only eight valves while an ABS modulator for ABS and STC (stability and traction control) has ten valves.
The method for replacing the unit is the same for both types. Check thoroughly when installing the new unit that the unit is the correct type.
