TMS-4 OVERVIEW
The Haltech TMS-4 is a simple, plug-and-play way to
monitor tyre pressures through your Haltech ECU.
The TMS-4 system is available in two kit forms, with
different tyre pressure sensors. These can be mounted
inside the tyre (HT-011600) or externally (HT-011601).
Both sets of sensors are able to warn of air leaks,
temperature variations, and when the pressure is over
or under a set level.
The external pressure sensors provided with the TMS-4
External Sensor Kit (HT-011601) can be fitted directly to
the valves on a car’s tyres without the need to remove
the tyres.

TMS-4 INSTALLATION
Receiver installation
Install the receiver in the vehicle using the mounting
hardware supplied. For best results installation
location should be high in the vehicle.
Connection
The TMS-4 receiver connects via the supplied TE MCON
to DTM-4 CAN Cable.
Upon powering up an audible beep will be heard from
the receiver to indicate it is on.
Sensor installation: Internal
1. Deflate each tyre and remove from the wheels
2. Remove the old tyre valve from each wheel
3. Install the sensor in the corresponding wheel
according to the position sticker on the sensor
4. Re-install the tyre, ensuring sensor is not damaged
during this process
5. Reinflate the tyre to the desired pressure
6. Perform a dynamic wheel balance

TMS-4 SETUP
Sensor installation: External
1. Remove the valve cap from the valve
2. Inflate tyre to desired pressure
3. Thread the anti-theft lock nut onto the valve
4. Install the sensor in the corresponding tyre
according to the position sticker on the sensor
5. Tighten the lock nut using the spanner provided
6. Check for leaks with soapy water
Enabling the TMS-4: NSP software
In NEXUS series ECUs the receiver is enabled through
Connections > CAN > Haltech CAN System: Tyre
Monitoring (TMS-4 Enable).
It should also appear in the menu tree once detected on
the Haltech CAN Bus and enabled from there.
Enabling the TMS-4: ESP software
In Elite series ECUs the receiver is enabled via the
Main Setup (F4 page), then Devices: Tyre Monitoring
(TMS-4 Enable).
Once enabled it will appear next to CAN Devices.

TMS-4 OPERATION
Assigning sensors to wheels
Pressure sensors can be re-assigned to any wheel in
the setup menu, which allows users swap wheels and
re-assign sensors without physically swapping parts.
By default sensors are assigned as per the stickers
on the sensors. Sensors can also be turned off in the
software if monitoring that wheel is not required.
Channels
The following data channels are available in both NSP
and ESP software, as shown in this image 
TMS-4 channels can be searched for by using the
keywords “tyre”, “tire”, and “wheel”.
Channels displayed:
• Per Tyre Pressure
• Per Tyre Temperature
• Per Tyre Sensor Voltage
• Per Sensor Pressure
• Per Sensor Temperature
• Per Sensor Battery Voltage
• Air Leak Detected (1 channel covers all 4 tyres)
• Recommended Tyre Pressures
(for logging and display purposes only)
NOTE: The recommended tyre pressures are values defined by
users under the sensor setup and assignment tab of NSP and
ESP software. These figures are only used for the convenience
of display and are NOT used in any calculations.

TMS-4 OPERATION
Air Leak Detection
The TMS-4 system can warn of air leaks in tyres.
Enabled by default in the software, Air Leak Detection
can use sensor logic, or be manually user-defined.
Sensor logic relies on the sensor flagging an air leak,
then signals a DTC based on that flag.
Users can also define their own pressure drop values
in the TMS-4 setup menu. If a pressure drop of that
value (or greater) occurs over a 5 second period then
the ECU flags an air leak.
Over / Under Pressure Detection
A DTC can be flagged when the air pressure readings
fall below, or rise above, the user-defined pressure
values for the front and rear pairs of tyres.
Users can set maximum and minimum pressure values
for pairs of tyres per-axle in the TMS-4 setup menu.
A DTC is triggered if the pressure drops or rises, to
under or over the pre-set values for 3 seconds or more.
Both internal and external sensors have a working
pressure range of 0-116 psi (0-800kpa).
Sensor Signal Loss Detection
A DTC triggers if signal loss is detected from any active
sensors. Signal loss can only be detected when sensors
are known to be awake so this requires vehicle speed
to be enabled, as sensors activate during pressure
change or when tyres are moving.
Diagnostic Trouble Codes
The TMS-4 can trigger several optional DTCs, including:
• Pressure High / Pressure Low
• Temperature High
• Air Leak Detected
• Sensor Battery Voltage Low
• Sensor Signal Loss
DTCs can be enabled within the TMS-4 setup menu. If a
sensor is not assigned to a tyre, it cannot trigger a DTC.
DTCs are referenced to the wheel the sensor is
assigned to. For example, if Sensor 3 (RL) is assigned
to the front left tyre and detects pressure is too low
the “Front Left Tyre Pressure Low” DTC will trigger.
Over Temperature Alert
A DTC is flagged if any sensor is at or above the user
defined maximum temperature entered.

TMS-4 MAINTENANCE
Battery Replacement - external sensors
The CR1632 battery used in the external pressure
sensors can be easily replaced.
1. Remove the sensor from the valve stem
2. Unscrew the cover from the sensor
3. Push the battery out of its holder
4. Gently push replacement battery in
5. Re-attach sensor to the valve stem
CR1632 batteries typically have a 1-2 year lifespan.
Battery replacement - internal sensors
The CR2023 batteries used in the internal tyre pressure
sensors are not replaceable.
These units have an average lifespan of 3 years, which
is longer than the average life of a tyre.
Low battery Voltage detection
A DTC will be triggered if any sensor battery falls below
2.3V. Individual battery voltages can be monitored by
the associated TMS-4 battery voltage channels.
