InstallatIon, servIce and troubleshootIng Procedures
DO NOT allow the cable to rub against
a sharp edge of a hole or straight edge
of a structural member. Use grommets
and/or loom to protect the cable from
sharp edges.
To restrain the harness:
1. Route harness under trailer as required.
2. Secure harness every 12 to 18 inches using
nylon ties or other wire management hardware
such as conduit or wire trays.
3. Support harness near connectors, as shown
in Figure 42, so the weight of the cable is
not supported by the connectors. Make sure
connections are secure and not able move around
during vehicle operation.
4. Bundle excess cable as shown in Figure 42.
TRAILER-MOUNTED INDICATOR LAMP INSTALLATION
Unless configured with lamp option, a trailer-mounted
indicator lamp (incandescent or LED) is NOT provided
with TIREMAAX
®
systems. Refer to Figure 41 on
page 33 for indicator lamp and wiring options and
details. Reference Refer to TMC RP 161 and 704.
Mount indicator lamp to trailer as follows:
1. Determine best location on the front corner or
side of the trailer within view of the driver side
view mirror.
NOTE: On truck applications with large wind fairings,
locating the indicator lamp near the left rear
wheels (near the ABS warning lamp) may be
preferable.
2. Mount indicator lamp at determined location
(fasteners not provided). Recommended assembly
torque is 17.5
±
2.5 in. lbs. (2.0
±
0.3 N•m) with
a #10 machine screw.
3. Connect indicator lamp wires according to
information provided in Figure 41 on page 33
and wire harness installation instructions on
page 34.
SYSTEM INTEGRITY CHECK
After the installation is complete, but before the trailer
is put into service, all air system connections must be
tested. To accomplish this:
A. Complete the procedure CHECKING FOR AIR LEAKS
on page 44.
B. Perform the INDICATOR LAMP TEST on page 45.
For PRO - The test procedure for validating proper
TIREMAAX PRO controller function during the
application of the emergency brakes should be as
follows:
1. Set the trailer emergency brakes by removing the
emergency/supply gladhand or simulating this
event by exhausting the pilot pressure at the PRO
controller.
Upon setting the emergency brakes, a brief
audible exhaust will be present at the controller.
The maximum allowable time limit for the audible
exhaust to be present is 10 seconds.
2. Once the audible exhaust has dissipated, a small
airflow can continue to be detected at the exhaust
port of the controller. Use leak detection solution
and observe bubble formation.
The maximum allowable time limit for bubble
formation to be present is 5 minutes. If the system
conforms to the allowable limits for audible
exhaust and leak detection criteria above, the
controller is considered to be within allowable
factory specifications.
SYSTEM SETUP
The TIREMAAX
®
controller is pre-programmed from
the factory, therefore no additional setup is required.
To program a pressure other than the factory setting,
follow the appropriate procedure:

PRESSURE on page 49
For PRO -
