ALDL 12 pins connector - frontal vision ALDL 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. 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. 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: 4A 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.
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. Some idle data transmission of trivial parameters, however, existed in many vehicles. Bidirectional communication also allowed many other functions to be performed via ALDL, such as actuator tests, parameter overrides, and in some cases even reprogramming of the itself. Multiple devices could be placed on the ALDL data line for primitive networking and communication. Many later 8192 baud vehicles, for example, had airbag control, ABS, and even climate control units sending data on the same serial bus. In both versions, ALDL data is sent in a format unique to the model of in the vehicle with little standardization between models, so a proper definition of the data is required to interpret it.
Most professional scan tools require a large database of vehicle definitions. The signaling of ALDL is similar to the standard; differing in the voltages used to denote logical one (usually 0 VDC) and logical zero (either +5 VDC or +12 VDC), and that unlike RS232, both transmit and receive functions are on the same conductor. Schematics are available on the internet for devices that can be used to convert the ALDL voltages to that of the RS-232 standard, allowing the raw data to be read with a computer having a and the proper software. Multiple scanner software programs are available. TunerPro RT is one of the most flexible and most popular. It covers most US applications.
94-95 6.5 Turbo Diesel scanner software is also available Direct USB to ALDL cables and even Bluetooth modules are available from suppliers like Red Devil River. References.
USB to ALDL CABLE Plug your laptop into the ALDL port of your 82 to 95 GM computer controlled car or truck and see what is happening under the hood. Use as a scan tool.
Compatible with GM OBDI data streams that use the 8192 Baud, Pin M protocol AND 160 Baud Pin E protocol. The cable may be ordered with the 12 pin connector shown here, the 94 & 95 16 pin connector, or with universal bare pins. 12 Pin versions have built in the 10K ohm resistor required by some ECMs. The resistor can also be switched off if needed. USB to ALDL Cable comes with 5' USB extension cable, and Driver/Software CD.
This cable is compatible with programs such as WinALDL and TunerPro RT. Use it with your Android device - Works with ALDLdroid! ALDLdroid sold separately - Check compatibility with your android device before purchasing. Ship to Connector type.
What is needed to monitor my engine? There are 3 things needed to access the diagnostic data stream from a GM based On Board Diagnostic 1 ( OBD1 ) system on your 1982 - 1995 car or truck. 1 - A laptop PC with an available USB port 2 - This ALDL to USB cable 3 - A software program running with the correct stream definition for your car or truck FAQs Q - Will this cable work with my OBD1.5? A - Yes it will. GM used 12 pin OBD1 type and 16 pin OBD2 type connectors on 94 & 95 vehicles.
Make sure you order the cable that fits your cars connector. Q.- Will this work with my 94-95 6.5 Turbo-Diesel? A - Yes it will however you will have to download and use GMTD Scan Basic (free) or GMTD Scan Tech ($) from Q - Does this cable include the 10K ohm A-B resistor needed on many 12 Pin 160 Baud ECMs? A - Yes it does.
Q - Can I disable the 10K ohm A-B resistor? A - Yes the 10K resistor can be switched off on the 12 Pin version. Q - Why would I want to disable the resistor? A - On a few select ECMs the 10K O resistor is not needed for the data flow but does alter the idle speed and timing. On MOST ECMs the 10K ohm resistor either does not affect the ECM operation, OR the 10K ohm resistor is needed for data flow. If you have questions on the 10K ohm resistor contact me.

Q - Can I get a version of the 16 pin cable with the switchable 10K O resistor? A - No, GM never required the 10K ohm resistor on the 16 Pin OBD1 vehicles and thus my 16 Pin cable has none.
