86-5-14 DESCRIPTION AND OPERATION
The immobilisation ECU is powered by a permanent battery feed from the passenger compartment fusebox. It also
receives an auxiliary power feed and an ignition power feed from the ignition switch. Power for the starter motor
solenoid is supplied to the immobilisation ECU when the ignition switch is in the crank position (on Td6 models) or on
a permanent feed from the passenger compartment fusebox (on V8 models). A connection with the K bus provides
the immobilisation ECU with engine speed and locking system status.
