The tables show live connector pins and also relevant earth
destinations for given gearbox functions/systems as follows:
ECU feeds and earths
(see previous pages)
Transmission Dump
(see previous pages)
Park Brake ON (Transmission Dump)
(see previous

The information is intended as an aid when checking for
faulty wires or connectors by means of continuity tests using
a multimeter. DO NOT use a multimeter on the ECU
connector pins (connectors A and B). Only test the
associated wiring, uncouple connectors GB and GC and
then use a multimeter at the pins inside these connectors as
applicable. Use the ShiftMaster Diagnostics system to
identify possible faults with the ECU See
Powershift
Gearbox - 6 Speed, ShiftMaster Diagnostics - User
Guide
.
Remember that any interconnecting harness connectors are
not shown here. For full details see the relevant expanded
harness schematic in this section.
Diagram X
The diagram
X
(opposite) shows the electrical circuit for the
