1. PURPOSE
This document is the Mounting procedure of the TCU.
TCU is a part of a Tire Pressure Monitoring System.
The Telematic Control Unit (TCU) collects information on the vehicle and transmits it over the
GSM network to a back-end server. It can capture data from CAN, GPS and TPMS.

4. TCU MOUNTING INTERFACE.
The TCU is mounted on a plane surface fixed on the vehicle frame. The TCU has 3 mounting
points equipped with silent blocks. The TCU must be fixed on a support (available on demand).
This support (TCU interface) is defined in the appendix.
5. TCU MOUNTING RECOMMENDATIONS
Screws (not provided by LDL) must be tightened @ 4,5 Nm +/-0,5 Nm. It's recommended to use
an elastic washer (Belleville type) between screw head and silent block with spacer. Stainless
steel is recommended.
M6 bolts are recommended, the screw for a fixation on a base plate fixation in thickness 2mm
must have a length equal or higher than 20mm.

LDL TCU bracket combinations
To link a base support to an extension support , 2 bolts are needed, type M6, length 16mm,
with 2 M6 washers (1 standard type and 1 Belleville type).
6. TCU POWER SUPPLY CONNECTION
Cable must be fastened between 100mm and 200 mm away from its TCU starting point.
Verify that no tension stress is applied onto the harness between TCU connector and the
fixation point onto the vehicle chassis AND after connection of the harness connector onto the
TCU connector.
From the TCU connector base to the fixation point away TCU (100 to 200 mm), the harness
cable must be in line as much as possible with the TCU connector terminal axis and not curved
over 30° see picture on next page below.
The connector must be secured after clipping (move the red CPA (Connector Position
Assurance) onto the harness connector toward the TCU connector)

Cable management in the TCU neighborhood.
Incorrect wiring will prevent the system from operating properly.
TCU has to be connected to +12V or +24V through 5A fuse protection.
TCU must be connected on Ignition (IGN).
When TCU and ECU or EBS are connected to a same CAN network, they must share the
same ground.
LDL Technology can provide the wiring harness (see table below) :
Nota : This cable has a minimum curvature radius about 80mm.

7. TCU LOCATING RECOMMENDATIONS
The TCU must be fixed horizontally and upside down (connector side facing the ground):
The TCU must be free from any metallic shield in the direction of the connector side.
The antenna should be cleared as possible to optimize RF communication and reduce areas of
non-receipt.
There must be a free area of minimum 5cm wide around the TCU in all directions.
TCU must not be exposed to gritting.
Each TCU must be at a central point between the wheels that it has to receive, and aligned on
the vehicle axis. Distance between TCU and WUS must not exceed 3 meters.
When trailer is equipped with an EBS, TCU bracket should be fixed to EBS bracket.
