Checking Automatic Stop (Montero, Pickup & Ram-50)
1)Operate wiper motor at low speed. See CHECKING WIPER MOTOR
OPERATION. Disconnect battery voltage to stop motor in any position
except park.
2) Using a jumper wire, connect 2 terminals indicated. See
AUTOMATIC STOP CHECK table. See Fig. 1. Connect 12 volts to terminal
indicated in table, and ground wiper motor bracket. Ensure motor parks
wiper arm.

FRONT WIPER RELAY
NOTE: On Pickup, Ram-50,intermittent wiper relay is incorporated
into wiper switch. See STEERING COLUMN SWITCHES article in
the ACCESSORIES/SAFETY EQUIP Section. Precis does not have a
front wiper relay.
Continuity Check (Montero)
Remove relay. Relay is located behind driver's kick panel.
Make sure continuity is present between terminals No. 2 and 5. See
Fig. 2 .

Intermittent Operation Check (Montero)
1) Connect battery voltage to terminal No. 1 and ground
terminal No. 6. See Fig. 2. Connect a jumper wire with test light
between battery positive and terminal No. 2.
2) Connect one end of a jumper wire to terminal No. 3 and
touch the other end to negative terminal on battery. Test light should
illuminate briefly and then go out after terminal No. 3 is touched to
battery ground.
FRONT WIPER SWITCH
NOTE: Front wiper switch is located on steering column.
See STEERING COLUMN SWITCHES article in the
ACCESSORIES/SAFETY EQUIP Section.
REAR WIPER MOTOR
Operation Check (Montero)
Disconnect wiring connector from wiper motor. Connect battery
voltage to one terminal and ground to other terminal to ensure
automatic operation. See REAR WIPER MOTOR OPERATION CHECK table for
terminal numbers and model application. See Fig. 3.

Automatic Stop Check (Montero)
1) Start motor operation by connecting battery voltage to one
terminal and grounding another terminal. See
REAR WIPER MOTOR OPERATION CHECK table. See Fig. 3. Disconnect wires
during operation to stop motor in mid-sweep.
2) Jumper terminals No. 2 and 3 together. Connect battery
voltage to remaining terminal and ground wiper motor bracket. Ensure
motor parks wiper arm.
REAR WIPER RELAY
Operation Check (Montero)
Relay is located to right of heater blower assembly. Leave
intermittent relay connected to wiring harness. Operate rear wiper and
check voltage at terminal No. 1. See Fig. 4. There should be 12 volts
when rear wiper stops. Zero volts should be present when rear wiper is
operating.

WIRING DIAGRAMS
How To Use The Wiring Diagrams
WIRING DIAGRAMS
INTRODUCTION
The wiring diagrams and technical service bulletins,
containing wiring diagram changes, are obtained from the domestic and
import manufacturers. These are checked for accuracy and are all
redrawn into a consistent format for easy use.
All diagrams are arranged with the front of the vehicle at
the left side of the first page and the rear of the vehicle at the
right side of the last page. Accessories are shown near the end of the
diagram.
Components are shown in their approximate location on the
vehicle. Due to the constantly increasing number of components on
vehicles today, it is impossible to show exact locations.
In the past, when cars were simpler, diagrams were simpler.
All components were connected by wires, and diagrams seldom exceeded 4
pages in length. Today some wiring diagrams require more than 16
pages. It would be impractical to expect a service technician to trace
a wire from page 1 across every page to page 16.
Removing some of the wiring maze reduces eyestrain and time
wasted searching across several pages. Today, the majority of diagrams
now follow a much improved format, which permits space for internal
switch details and connector shapes.
Any wires that don't connect directly to their components are
identified on the diagram to indicate where they go. There is a legend
on the first page of each diagram, detailing component location. It
refers you to sub-systems, using grid NUMBERS at the top and bottom of
the page and grid LETTERS on each side. This grid system works in a
manner similar to that of a road map.
HOW TO USE THE WIRING DIAGRAMS
1) On the first page of the diagram, you will find a listing
of major electrical components or systems. Locate the specific
component or system you wish to trace. A grid number and letter will
follow the component's name.
2) Use the grid NUMBERS (arranged horizontally across the top\
and bottom of each page) to find the page of the wiring diagram that
contains the component you're seeking. When you reach this page, use
the grid LETTERS on the side of the page to determine the component's
vertical location.
3) Locate the circuit you need to service. The internals are
shown for switches and relays to assist you in understanding how the
circuit operates.
NOTE: In some of the newer wiring diagram articles in this
product, there is a Legend for the wiring diagrams that has
been created to make locating components easier. For these
articles, there will be a COMPONENT LOCATION MENU title in
the article main menu. These articles will also have the
original legend available on the first graphic.

WIRING DIAGRAM SYMBOL IDENTIFICATION
NOTE: Standard wiring symbols are used on diagrams. The list below
will help clarify any symbols that are not easily understood
at a glance. Most components are labeled "Motor", "Switch" or
"Relay" in addition to being drawn with the standard symbol.
