Universal (CHT340) HS/MS-CAN Switch | ELM327 Interface Cable (USB)

The Universal CHT340 is an ELM327 interface cable equipped with an integrated HS/MS-CAN switch. This cable connects to the vehicle via the OBD2 port and communicates with a computer via a USB connection, ensuring a stable and reliable connection for diagnostic purposes.

The unique feature of this interface cable is the built-in switch that allows easy switching between High-Speed CAN (HS-CAN) and Medium-Speed CAN (MS-CAN) networks. This significantly expands diagnostic capabilities by providing access to modules located on the MS-CAN network, such as air conditioning, audio, and other comfort systems, alongside the standard engine and transmission control systems on the HS-CAN.

Application and functionality:

This interface cable is suitable for performing various diagnostic tasks and adjusting parameters in compatible vehicles.

• HS/MS-CAN Switch: Enables access to both HS-CAN and MS-CAN networks, increasing diagnostic coverage for specific vehicles.
• Fault Code Diagnosis: Reading and clearing diagnostic trouble codes (DTCs) from various modules.
• Live Data Monitoring: Real-time reading of sensor data and operational parameters of the vehicle.
• Module Configuration: Provides the ability to configure or activate certain settings and functions of vehicle modules.
• Software Compatibility: Works with ELM327-compatible diagnostic software that supports the HS/MS-CAN switch function.

Compatible vehicles and applications:

This interface is suitable for a wide range of OBD2-compatible vehicles. The integrated HS/MS-CAN switch makes the adapter specifically useful for extensive diagnostics and functionality in vehicles from, among others, Ford, Mazda, and Lincoln, where these separate CAN networks are common.

• All OBD2-compatible vehicles (from 1996 in the US, 2001 in Europe for gasoline vehicles, and 2004 for diesel vehicles).
• Specifically enhanced functionality for Ford, Mazda, and Lincoln vehicles with HS-CAN and MS-CAN networks.

Compatible software and applications:

This ELM327 interface cable works with various diagnostic software packages that support the ELM327 protocol and can specifically utilize the HS/MS-CAN switch.

• FORScan (Windows): Provides extensive diagnostics, monitoring, and configuration for Ford, Mazda, and Lincoln vehicles, including access to MS-CAN modules.
• ELMConfig (Windows): Specifically designed for adjusting parameters and functions in Ford vehicles.
• FoCCCus (Windows): A tool for diagnosis and configuration of specific Ford models such as the Focus and Kuga.
• ScanMaster ELM (Windows): A general OBD2 diagnostic program for reading basic information.

Compatible operating systems:

The USB interface makes this cable compatible with the following operating systems.

• Windows: Windows XP, Windows Vista, Windows 7, Windows 8, Windows 10, Windows 11 (both 32-bit and 64-bit versions)

Supported protocols and systems:

This interface supports the standard OBD2 protocols and offers extensive compatibility with vehicle networks by enabling switching between CAN buses.

• ISO 15765-4 CAN (HS-CAN): The most common CAN protocol for engine and transmission control, standard OBD2 communication.
• ISO 15765-4 CAN (MS-CAN): Used for modules such as air conditioning, audio, and comfort systems, often found on Ford vehicles.
• ISO 14230-4 KWP (KWP2000): An older protocol, used in many Asian and European vehicles.
• ISO 9141-2: An older protocol, widely used in Asian, European, and Chrysler vehicles.
• J1850 VPW / J1850 PWM: Protocols mainly used in American vehicles (GM and Ford respectively).
