SNOW MODE SWITCH
Revision: 2004 November 2004 FX35/FX45
SNOW MODE SWITCHPFP:25130
DescriptionABS00CFL
NOTE:
If DTC U1000 or U1001 are displayed, first perform the trouble diagnosis for DTC U1000, U1001.
Refer to EC-792, "
DTC U1000, U1001 CAN COMMUNICATION LINE" .
The snow mode switch signal is sent to the “unified meter and A/C amp.” from the snow mode switch. The
“unified meter and A/C amp.” then sends the signal to the ECM by CAN communication line.
The snow mode is used for driving or starting the vehicle on snowy roads or slippery areas. If the snow mode
is activated, the vehicle speed will not be accelerated immediately than your original pedal in due to avoid the
vehicle slip. In other words, ECM controls the rapid engine torque change by controlling the electric throttle
control actuator operating speed.

to BCM terminal 55.
through 15A fuse [No.22, located in the fuse block (J/B)]
to BCM terminal 42.
With the ignition switch turned to ON or START position,
Power is supplied
through 15A fuse [No.1, located in the fuse block (J/B)]
to BCM terminal 38.
Ground is supplied
to BCM terminal 49 and 52
through body grounds M35, M45 and M85.
to A/C and AV switch terminal 5
through body grounds M35, M45 and M85.
to IPDM E/R terminals 38 and 60
through body grounds E21, E50 and E51.
When rear window defogger switch in A/C and AV switch is turned to ON,
Ground is supplied
to BCM terminal 9
through A/C and AV switch terminal 16
through A/C and AV switch terminal 5
through body grounds M35, M45 and M85.
Then rear window defogger switch is illuminated.
Then BCM recognizes that rear window defogger switch is turned to ON.
Then it sends rear window defogger switch signals to IPDM E/R, display control unit (with navigation system)

through body grounds E21, E50 and E51,
and then rear window defogger relay is energized.
When rear window defogger relay is turned ON,
Signals are transmitted,
through rear window defogger relay terminals 5 and 7
to rear window defogger terminal 1
Rear window defogger terminal 2 is grounded through body grounds B15 and B45.
With power and ground supplied, rear window defogger filaments heat and defog the rear window.
When rear window defogger relay is turned to ON,
Power is supplied
through rear window defogger relay terminal 7
through fuse block (J/B) terminal 2C
through 15A fuse [No. 8, located in the fuse block (J/B)]
through fuse block (J/B) terminal 5B
