System Relay: Description and Operation
Bendix

Sent by the fuel injection ECU:

PURPOSE

The system relay  provides current to the fuel pumps, suppressor relay, idle air valve, oxygen sensor pre-heating resistor and to other ECU
controlled functions or components.

LOCATION

Located in center console behind the ash-tray.

OPERATION

The fuel injection ECU controls the relay ground connection. When ground is supplied, the system relay is activated and currant can flow to all the
related components. If the ground connection is interrupted, no current can reach the components.
