71-138 WIRING - SYSTEM CIRCUIT DIAGRAM

Description:

When the ignition switch is ON, the current passes through fuse F26 in the body fuse
box to pin 1 of diesel filter & heater relay R9 in the engine compartment fuse box and is
grounded at pin 2 via the coil. When the coil is energized, a magnetic field is produced
and the contact is closed. When the battery current flows from fuse F7 in the engine
compartment fuse box to pin 3 of the diesel filter & heater relay. After passing through
the contact, it outputs from pin 5 to pin A of the diesel filter & heater and is grounded via
pin B to activate the system.
