The first edition of the standard ISO 7638 was issued in 1985. Its purpose was to create a standardized system for the transfer of signals regarding the anti-lock braking system (ABS) from towing vehicles to heavy trailers. In 1997, the standard was split into two parts withISO 7638-1 covering 24V systems and ISO 7638-2 covering 12V systems. The next review was issued in 2003. It updated the previous edition concenring requirements for the connection of running gear. The latest version of the two-part standard is from 2018.
Description:
1. ISO 7638 7-pin (EBS ABS) adapter is a special cable adapter for connecting for Bosch,for autel, for launch,for Autocom and other truck vehicles. Connected to trailers (semi trailers) and trailers via ISO 7638 7-pin connectors. With 24v/5v external power supply, no tractor.(NOTE:Do not supported by Delphi systems.)
2. The ISO 7638 diagnostic adapter allows you to diagnose a trailer without connecting it to a truck.
3. The adapter can be connected to an additional 5v-24v power supply.
4. ISO 7638 cables are fully compatible with trailers equipped with Knorr Bremse tebs and tebs g2.0/2.1 braking systems.
5. The adapter has ISO 7638 "male" connector, ISO 7638 "Female" connector, OBD2 connector and connector for connecting external power supply.
6. It is connected in series with the EBS Trailer cable or only with an external power trailer.
7. The cables have been tested and are 100% compatible with Knorr tebs and tebs G2.
8. EBS ISO 7638 cable is applicable to all cargo scanners supporting K-line, can, can 5V, etc.
9. EBS ISO 7638 provides the ability to diagnose, reset errors, perform valve checks, program valves and save valve programs on disk, delete daily operations of trailers, and view current parameters.
Application and features of ISO 7638-1 and -2
The ABS/EBS (Electronic Braking System) connectors for truck and trailer are used on nearly every commercial vehicle type withABS/EBS System. They include various safety features: If a plug is incorrectly plugged in, it is automatically ejected by an ejector pin. Furthermore, the socket and plug housing of the12V and the 24V systemshow different codings. This feature effectively avoids an accidental connection between components of the standard ISO 7638-1 and ISO 7638-2 thus protecting the electrical system from possible damage.
Pins 6 and 7 of the 7-pin standard are used forCAN-Busdata lines according to ISO 11992. As a CAN-Bus connection is not necessary for the functionality of the ABS system, there is also a 5-pin variant of this connector without pins 6 and 7.
Scope of ISO 7638-1 and 7638-2
The standards ISO 7638-1 and 7638-2 specify
· the dimensional characteristics of 7-pin connectors for the electrical connection of braking systems and running gear used in towing and towed vehicles with 24 V (ISO 7638-1) or 12 V (ISO 7638-2) nominal supply voltage
· the contact allocation as well as tests and requirements for the trailer connector system
· a park socket for receiving and storing the plug when it is disconnected
Contact Allocation for Connectors According to ISO 7638-1 (24V) and 7638-2 (12V)
Trailer socket according to ISO 7638-1 or ISO 7638-2 with contact allocation in the cover.
