61-48 CIRCUIT - SYSTEM SCHEMATIC DIAGRAM

System description:
The battery provides the power to the main fan relay R05 pin 30 via the fuses F28 and F12
in the engine compartment fuse box.
Fan low speed control
The battery current provides electric power to the main fan low speed position relay R05
pin 30 via the fuses F28 and F12 in the engine compartment fuse box. The main fan low
speed position relay R05 is controlled by the engine electronic control module pin 26. The
coil is electrified to generate a magnetic field to cause the main fan low speed position
relay R05 contact closed, and the current is output from the main fan low speed position
relay R05 pin 87 via the contact into the man fan motor pin 2, earthed via the fan motor pin
3; then the main fan motor works at a low speed.
Fan high speed control
The battery current provides electric power to the main fan high speed position relay R16
pin 30 via the fuses F28 and F12 in the engine compartment fuse box, and the main fan
high speed position relay R16 is controlled by the engine electronic control module pin
27. The coil is electrified to generate a magnetic field to cause the main fan high speed
position relay R16 contact closed, and the current is output from the main fan high speed
position relay R16 pin 87 via the contact into the man fan motor pin 1, earthed via the fan
motor pin 3; then the main fan motor works at a high speed. The battery current provides
electric power to the auxiliary fan relay R04 pin 30 via the fuses F28 and F16 in the
engine compartment fuse box, and the auxiliary fan relay R04 is controlled by the engine
electronic control module pin 27. The coil is electrified to generate a magnetic field to
cause the contact closed, and the current is output from the auxiliary fan relay R04 pin 87
via the contact into the auxiliary fan motor pin 1, earthed via the fan motor pin 2; then the
auxiliary fan motor starts to run.
