1 Introduction The Telematics Control Unit (TCU) integrates an on-board cellular communication module with a WiFi hotspot functionality and interacts with remote call/data centers to provide valuable services to the vehicle customer. 1.1 Purpose and Scope This document aims to describe the device operating principles and provide installation instruction to OEM to insure safe use of the device. 1.
1.3 Power and Grounding The TCU is designed to operate via an unfiltered 5 A fused input from the vehicle battery: Vbatt Ground return is through a single ground pin: GND 1.3.1 Power and Grounding Operating voltage range is provided in the following table. Table 3.1.1 TCU Operating Voltage Conditions Voltage Range (Vdc) 9.0 < VBATT < 16.0 Subsystem Operating Conditions Normal operation. TCU is fully functional The VBATT connection (pin 17) shall support up to 2.5A current draw with 4.5A peaks.
The threshold voltage transition from Backup Battery to Vehicle Battery: If the VBATT voltage transitions upward from <7.7V to >9.0V AND BUB voltage > 2.0V, the DCM shall begin using the VBATT as a power source (i.e. switch to +B). The DCM shall continue to be OPERATING ON VBATT until the conditions of DCM_02552 or DCM_00031 are met. 1.3.2 Backup Battery (BUB) BUB refers to the Back-up Battery installed in the DCM; the DCM is shipped to Subaru with a BUB installed.
1.4 WiFi The TCU supports IEEE 802.11a/b/g/n/ac 2.4/5GHz WiFi. 1.4.1 WiFi internal Antenna The TCU contains integrated pcb type F dual band antenna with the following maximum gain Frequency 2442 MHz 5220 MHz 5785 MHz MAX Gain 3.14 dBi 0.68 dBi 1.94 dBi 1.5 Connectors 1.5.1 USB Connector 2 4 1 3 Shield USB Connector – pin details (View from mating side) Pin No.
1.5.2 RF Connector RF Connector – pin details (View from mating side) Terminal Name Primary Secondary GPS Terminal Description Input(I) / Output(O) TEL MAIN antenna signal TEL MAIN antenna GND TEL SUB antenna signal TEL SUB antenna GND GNSS antenna signal GNSS antenna GND I GND I GND I GND 1.5.
1.6 TCU Module Label The TCU labeling shall comply with the regulatory homologation compliance mark(s) that are required by law in those countries. Art work for Subaru T19Plus US is shown below: The module is marked with the Automotive OEM company trademark, engineering part number, and supplier code. 1.
2 Vehicle Installation Guidelines Normal operating conditions are between -30°C to +85°C. The sheet metal cover is designed to be a heat sink. A gap between the heat sink and the mounting surface is recommended to facilitate heat transfer out of the module. Exceptions can be made if the module is mounted to a surface that can help facilitate heat transfer such as a large aluminum body panel. The device does not have sealed connectors.
3 Regulatory Compliance Notes FCC: This device complies with Part 15, Part 22(H), Part 24(E) and Part 27 of the FCC Rules. The FCC ID for this device is LHJ-STRLNK2P. It also contains a certified module with FCC ID: LHJ-BL28NA003. Part 15 (WiFi) operation is subject to the following two conditions: 1. This device may not cause harmful interference. 2. This device must accept any interference received, including interference that may cause undesired operation.
4 External Antenna Requirements for use with T19Plus US Device The T19Plus US device is for use with external antennas ONLY, except for Wi-Fi which uses an internal antenna.
