Question about 2002 Lexus LX 470
My wife's 2002 LX-470's center diff switch has become stuck in the engaged position. I am hesitant to drive it 30 miles to the nearest service center this way. Owners manual indicates that electric service flows through fuse #40 in drivers kick panel, if I pull this fuse will the diff lock disengage? Also the switch when actuated does seem to click a relay under the glove box but car still remains in diff lock mode. Any ideas?
Yes it will, once no power is going to it it should or it could remain locked as well Give it a try . But you should have a look at the relay
that is what the pins should look lik 1 - 4 should power it
try grounding pins 1 - 4 this should lick or unlock the diff..

FOUR-WHEEL DRIVE SYSTEM
(a) Four-wheel drive control
Use the four-wheel drive control lever and center
differential lock button to select the following transfer and
center differential modes.
The "H" and "L" position of the four-wheel drive control lever
provides either lock or unlock mode of the center differential
depending on the center differential lock button position.
Use the center differential lock system if your wheels get stuck
in a ditch, or when you are driving on a slippery or bumpy
surface. When the center differential is locked, the vehicle
stability control system is automatically turned off and the
center differential lock and "VSC OFF" indicator lights come on
because the function that controls engine performance
As soon as the center differential lock switch is turned
on, the "VSC OFF" indicator light comes on. After the
wheels are out of the ditch or off the slippery or bumpy
surface, turn the center differential lock switch off.
Make sure the center differential lock indicator light and
vehicle stability control system off indicator light turn
"H" (high speed position, center differential unlocked):
Lever at "H", center differential lock button left out
Use this for normal driving on all types of roads, from dry
hard-surfaced roads to wet, icy or snow-covered roads. This
position gives greater economy, quietest ride, least wear and
better vehicle control.
"H" (high speed position, center differential locked): Lever
at "H", center differential lock button pushed in
Use this for greater traction when you experience a loss of
power, such as wheel slipping, in the center differential unlock
"N" (neutral position): Lever at "N"
No power is delivered to the wheels. The vehicle must be
"L" (low speed position, center differential unlocked):
Lever at "L", center differential lock button left out
Use this for maximum power and traction. Use this for climbing
or descending steep hills, off-road driving, and hard pulling in
sand or mud.
In this mode, the braking feeling that occurs when the wheels
are negotiating a sharp corner is further reduced than in the "L"
(low position, center differential locked) mode.
"L" (low speed position, center differential locked): Lever
at "L", center differential lock button pushed in
Use this for maximum power and traction. Use this for hard
pulling in situations the vehicle cannot negotiate even in the "L"
(low speed position, center differential unlocked) mode. Also,
using this mode when driving down steep off-road inclines will
help contribute to increased vehicle stability.
