SECTION 55 - ELECTRICAL SYSTEM 171
POWERSHIFT CONTROL UNIT
The control unit receives the signals switching ON or
OFF the solenoids and allowing the desired gears to
be selected. A variable current solenoid receives a
reducing signal from the EGS controlling modulator.
The control unit is equipped with a combined tem-
perature and speed sensor which sends signals
back to the EGS.
Test Procedure
