24 DEB
OPERATION
A voltage is applied to D813 (gearbox gate
safety electronic unit), D550 (ABS/ASC-D
electronic unit) and to contact 3 of relay G243
(engine brake micro relay) through fuse E019. If
the ABS/ASC-D electronic unit is not active, the
voltage is also applied to both switch C754
(engine-brake switch VF engine) and the Daf
Cummins Interface electronic unit. Depending
on the Daf Cummins Interface electronic unit or
the position of switch C754, relay G243 will be
activated and a voltage applied to valves B247
and B248.
If no Cummins Celect is present, relay G243 is
activated directly by CTE-2 (D550).
