This manual provides you the information
necessary for the proper operation and
maintenance of the Electronic Lock Indicator
System (ELI) for the Holland FW35 series
fifth wheels.
You must read and understand all of the
procedures presented in this manual before
operating or starting work on any Electronic
Lock Indicator System (ELI) for the Holland
FW35 series fifth wheels.
IMPORTANT: Keep this manual in
a safe location for
future reference.
Proper tools must be used to perform
the maintenance and repair procedures
described in this manual.
NOTE: In the United States, work
shop safety requirements are
defined by federal and/or state
Occupational Safety and Health
Acts. Equivalent laws may exist
in other countries. This manual is
written based on the assumption
that OSHA or other applicable
employee safety regulations are
followed by the location where
work is performed.
Throughout this manual, you will notice the
terms “NOTE,” “IMPORTANT,” “CAUTION,”
and “WARNING” followed by useful product
information. So that you may better
understand the manual, those terms are
defined as follows:
NOTE: Includes additional information
to enable accurate and easy
performance of procedures.
IMPORTANT: Includes additional
information that if
not followed could
lead to hindered
product performance.

Fifth wheel serial tags are located on the
left side of the fifth wheel top plate above
the fifth wheel bracket pin, or on the pickup
ramps as shown (Figure 1).

FAILURE TO PROPERLY INSTALL, MAINTAIN & OPERATE
THIS PRODUCT COULD RESULT IN TRACTOR TRAILER
SEPARATION CAUSING SERIOUS INJURY OR DEATH.
Read and observe all Warning and Caution
hazard alert messages in this publication.
They provide information that can help
prevent serious personal injury, damage
to components, or both.
The Electronic Lock Indicator System (ELI)
installation and maintenance must be
performed by a trained technician using
proper tools and safe procedures.
IMPORTANT: The Electronic Lock
Indicator (ELI) is a
tractor-trailer fifth
wheel coupling aid
and is intended as
an additional safety
check to assure the
driver of a safe and
complete coupling. It
does not eliminate the
requirement for a visual
inspection of the fifth
wheel. Always get out
of the tractor cab and
visually inspect the
fifth wheel coupling
before proceeding.
Failure to follow all the
operating procedures
contained in these
instructions may result
in a hazardous condition
which, if not avoided,
could result in death
or serious injury.
These instructions apply to the proper
operation of your fifth wheel only. There
are other important checks, inspections,
and procedures listed in the Owner’s
Manuals for your tractor and trailer that are
necessary, prudent, and/or required by law.
Only SAF-HOLLAND Original Parts should
be used.

fifth wheel you must be
thoroughly satisfied that
the fifth wheel has been
appropriately installed
on the vehicle.
Failure to properly install,
the fifth wheel may result
in tractor-trailer separation
which, if not avoided, could
result in death or serious injury.
1. For pulling trailers with standard SAE
kingpins which are in good condition
and securely mounted or locked in
position in the trailer.
2. To transport loads that are within the
maximum fifth wheel rated capacities:
55,000 lbs. Maximum Vertical Load
150,000 lbs. Maximum Drawbar Pull.
3. In both on-road and off-road applications.
IMPORTANT: SAF-HOLLAND definition
of off-road refers to
terrain on which a
tractor-trailer operates
which is unpaved and
rough, or ungraded. Any
terrain not considered
part of the public
highway system falls
under this heading.
4. As recommended in SAF-HOLLAND
literature available at www.safholland.us.
4. Fifth Wheel
NON-Intended Use
1. Use with non-SAE kingpins, such as
kingpins which are bent, improper size
or dimensions, not secured to maintain
SAE configuration, or which are installed
in warped trailer bolster plates, or upper
coupler and fifth wheel lube plates
that do not maintain the SAE kingpin
dimensions. Refer to SAF-HOLLAND
Service Bulletin XL-SB004-01 (available
on the Internet at www.safholland.us)
for more information on fifth wheel
lube plates.
Failure to couple with a
proper kingpin may result
in improper coupling,
allowing tractor-trailer
separation, which if not
avoided, could result in
death or serious injury.
2. Tow-away operations which damage
or interfere with the proper operation
of the fifth wheel.
3. The attachment of lifting devices.
4. The transport of loads in excess of
rated capacity.
5. Applications other than recommended
in SAF-HOLLAND literature available at
www.safholland.us.
5. Coupling Preparation
NOTE: Follow the coupling and
uncoupling instructions
published in your Fifth
Wheel Owner’s Manual.
6. Operation Procedures
The Electronic Lock Indicator (ELI)
automatically turns on when the tractor
is started and remains on until the vehicle
is turned/shut off.
When the tractor is started, the display
first performs a short system check,
indicated by the brief illumination of
all three display icons.
After the system check, one of three
displays will appear:
t5IFEJTQMBZJOEJDBUFTBZFMMPXGJGUI
wheel icon when the fifth wheel is
in the proper position for coupling.
There is not a kingpin in the fifth
wheel lock and the fifth wheel
lock mechanism is in the unlocked
position (Figure 3). Follow the
coupling procedure in the Fifth Wheel
Owner’s Manual that came with your
fifth wheel.
NOTE: If you will be traveling without
a trailer, this display will remain
lit for approximately seventeen
(17) minutes before turning
off. The display will turn back
on during the next coupling
process, or the next time it is
turned on.

lock icon when the fifth wheel is
properly coupled to a trailer kingpin.
The kingpin is in the lock at the proper
height and the lock mechanism is
fully closed in the locked position
(Figure 4). Proceed with a visual
inspection. The display will remain lit
for approximately eight and one-half
(8-1/2) minutes before turning off.

The open lock icon is flashing red in
this mode (Figure 5). The Stand-Alone
On-Dash mounted unit will also display
one of nine (9) error codes (see page 8
for error code descriptions).
The proper response to improper couple
signal (Figure 6) is as follows:
IMPORTANT: If a flashing red fifth
wheel icon and open
lock icon appears while
operating the vehicle,
immediately pull over
in a safe area out of the
flow of traffic. Follow
the steps outlined
below to determine
if the fifth wheel is
properly coupled.
1. Perform a visual inspection referring
to the instructions included in the
Owner’s Manual that came with your
fifth wheel.
2. If the visual inspection indicates that
the fifth wheel is properly coupled:
