ALDL 12 pins connector - front view Assembly Line Diagnostic Link or ALDL is a proprietary system developed by before the standardization of. It was previously called Assembly Line Communications Link or ALCL.

The two terms are used interchangeably. This system was only vaguely standardized and suffered from the fact that specifications for the communications link varied from one model to the next.

Assembly Line Diagnostic Link or ALDL is a proprietary on-board diagnostics system. The connector is usually located under the dash on the driver's side of. Turbo Diesel scanner software is also available Direct USB to ALDL cables. Plug your laptop into the ALDL port of your 82 to 95 GM computer controlled. USB to ALDL Cable comes with 5' USB extension cable, and Driver/Software CD.

ALDL was largely used by manufacturers for diagnostics at their dealerships and official maintenance facilities. The connector is usually located under the dash on the driver's side of left-hand drive (LHD) vehicles, though this location was not standardized. For the assembly plant test system computer that was connected to this vehicle connector and known by the same name, see the article.

In the late 1980s the system was migrated to the ADTS system (ALDL Development and Test System) which utilized an industrialized IBM PC with custom interface hardware. Diagnostic connector [ ] There were at least four different connectors used with ALDL. General Motors implemented both a 5-pin connector and a 12-pin connector, with the 12 pin connector (Packard/Delco/Delphi part number 12020043) being used in the vast majority of GM cars.

Lotus implemented a 10-pin connector. The pins are given letter designations in the following layouts (as seen from the front of the vehicle connector): 12-pin ALDL connector pinout F E D C B A G H J K L M 10-pin ALDL connector pinout A B C D E K J H G F 5-pin ALDL connector pinout A B C D E Note the difference in pin ordering between the connectors and the fact that the letter I is not used.

Unfortunately, the definition of which signals were present on each pin varied between vehicle models. Calculator. There were generally only three pins used for basic ALDL —ground, battery voltage, and a single line for data—, although other pins were often used for additional vehicle-specific diagnostic information and control interfaces. No battery voltage is present in the 12 pin ALDL connector. Data stream [ ] The earliest implementations of ALDL were unidirectional and transmitted serial data at 160 using. Some 160 baud models constantly transmitted sensor data on startup, while others started transmitting data when placed in diagnostic mode with a resistor connected to the ALDL port. Later versions were bidirectional and operated at a much faster (but incredibly slow compared to today's standards) rate of 8192 baud. Implementations using the 8192 baud rate were primarily request-driven, meaning that the main diagnostic data was not transmitted until a request was made.
