Check in sequence the new control module:
-
The surfaces of heat conductor pole -1- for oxidation to ensure good heat conductibility.
-
The protrusion dimension of the heat conductor pole, which must protrude 0.8 to 1.0 mm between the upper edge of the heat conductor poles
-1- and seal -2-.
-
The suspension of the heat conduction poles. For this, the heat conduction poles must be pressed and released again, during which they must
spring.
If a problem is detected during a check, the control module must be replaced.
Continuation for all vehicles
^
Clean sealing surface of the hydraulic unit e.g. with mineral spirits.
When attaching control module -a- and hydraulic unit -b-, be sure that valve domes -1- of the hydraulic unit do not jam with magnetic coils -2- of the
control module.
^
Set control module onto hydraulic unit.
^
First, thread in new bolts -1- and -2- altermatingly to end by hand.
Ensure that the control module is centered on the groove of the hydraulic unit.
^
Thread in new bolts -3- and -4- and then new bolts -5- and -6aternating to end by hand.
^
