Document Revision History

Introduction

Document scope
This document describes the Honda 4G TCU device. The description contains a step-by-step connection guide and a description of connections. A detailed description of LED behavior and mounting instructions are provided to ensure correct usage of the device.

Hardware overview

TCU connection
Connecting the harness to the TCU.

For powering up:

• Connect KL31 to ground of power supply
• Connect KL30 to 12V power supply
• Connect KL15 to KL30 (Ignition Pin)
• Connect USB to the computer for debugging purposes

Pinout overview

Relevant PINs

LED behavior

The LEDs on the TCU are used to signal different information, depending on their state. General TCU state:

• All LEDs on for 1 second = TCU is started
• All LEDs on for approx. 10 seconds = TCU is going into suspend
• All LEDs flicker (250 ms on, 250 ms off) = Configuration (config.json) missing or invalid (wrong format or values) Individual feature state:

LED 1 (yellow) = LTE:

• Off = LTE not connected
• Blinking = Establishing LTE connection
• On = LTE connected

LED 2 (white) = Wi-Fi:

• Off = Wi-Fi not connected
• Blinking = Establishing Wi-Fi connection
• On = Wi-Fi connected

LED 3 (blue) = AWS:

• Off = AWS not connected
• Blinking = Establishing AWS connection
• On = AWS connected

LED 4 (orange) = GPS:

• Off = no GPS fix
• On = GPS fix

Mounting position of the TCU

To have a good signal reception consider the following points for mounting:

• clear view to the sky
• avoid metallized windshields
• minimum 3 cm clearance on every side of the TCU
• the TCU shall not be „boxed-in“ by metal objects
• no harness routing over or next to the antennas / the TCU
• Other devices which may cause harmful interference must be placed as far away from the TCU as possible

3rd party code and licensing

This section lists possible foreign code parts (libraries, reused components etc.) that the concept suggests. This is restricted to the application only. The platform software uses many FOSS and proprietary foreign code components that are not considered here.
FOSS Components

MQTT Library
Mosquitto, an open-source MQTT library, is used by the MosquittoClient component. Mosquito is BSD licensed (http://mosquitto.org/COPYING.txt)

Logging framework
A logging framework is included for better debugging and diagnostics. SPDLOG was integrated to that purpose, which is licensed under the MIT License.

JSON library
For creating and parsing JSON objects RapidJSON is used. RapidJSON is licensed under MIT License.

AWS IoT Core SDK
For connection to the AWS IoT Core Backend, the SDK v2 for cpp was added. It is licensed under the Apache 2.0 license.

Proprietary Components
At this time, no proprietary licensed code parts are part of the concept for the application.

Certification

Japan

• The EU variant is pre-certified by DSPR
• Model Name: STP-MID EU A3C1203560000
• Vendor Name : Continental Engineering Services GmbH
• Certified Number: 003-220347
• Certified Date: March 17, 2023

FCC ID 2BDLN-STPMIDNA

The device must be installed to provide a separation distance of at least 20 cm from all persons. This device complies with part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) This device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation.

Note: This equipment has been tested and found to comply with the limits for a Class B digital device, according to part 15 of the FCC Rules. These limits are designed to protect reasonably against harmful interference in a residential installation. This equipment generates, uses and can radiate radio frequency energy and, if not installed and used under the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. Suppose this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on. In that case, the user is encouraged to try to correct the interference by one or more of the following measures:

• Reorient or relocate the receiving antenna.
• Increase the separation between the equipment and the receiver.
• Connect the equipment into an outlet on a circuit different from that to which the receiver is connected.
• Consult the dealer or an experienced radio/TV technician for help.

NOTICE: Changes or modifications made to this equipment not expressly approved by Continental may void the FCC authorization to operate this equipment.
