Should be suitable for most modern GM cars - Buick, Cadillac, Chevrolet, Daewoo
GMC, Holden, Opel, Vauxhall.
Most GM cars produced in 1996-2003 use J1850-VPW interface. GM cars produced in 2003-2006 use J1850-VPW interface or CAN. Most cars produced after 2006 are equipped with CAN bus.

Some OBD-II cables schemes:
The ALDU1 is a datalogger designed to work with OBD I GM vehicles.
The ALDU1 is compatible with the CABL1 and the CABL2, which are interface cables that connect to GM OBD I and OBD II vehicle respectively.
The ALDU1 can be purchased by itself, or as a combo with either the CABL1 or CABL2.
CABL1 is used for ~88-94 GM OBD1 vehicles with a rectangular ALDL connector like this:
CABL2 is used only on 95 (and some late-year 94) vehicles that still speak ALDL but have the D shaped “OBD2-style” connector like this:
It can be interfaced with many pieces of software, including TunerPro.
In the event you need to build a custom cable, use the following pin outs for the RJ45 connector:
This is the 86-94 original ALDL connector:
- pin A is connected to RJ45 pin 1
- pin B is connected to RJ45 pin 2
- pin E and pin M are connected to RJ45 pin 3
- pin G is connected to RJ45 pin 4
- other pins are not connected
This is the late model ALDL connector used in 1995:
- Pins 4 and 5 are connected to RJ45 pin 1
- Pin 13 is connected to RJ45 pin 2
- Pin 9 is connected to RJ45 pin 3
- Pin 16 is connected to RJ45 pin 4
- Pin 2 is connected to RJ45 pin 5
- Pin 10 is connected to RJ45 pin 6
- Pin 14 is connected to RJ45 pin 7
- Pin 6 is connected to RJ45 pin 8
Take a look at the OBD1 GM section of our online store here
The first step towards determining if your ALDU1 is working correctly is to look at the USB side. Before you continue, you should have verified USB connectivity and you will need to know which COM port your cable is using. Take a look at the USB troubleshooting guide if you have any questions or concerns here.
You will need to have TunerPro RT version 5.0 or later installed.
- Start TunerPro RT with your cable plugged into your computer but unplugged from the vehicle.
- Load a valid XDF / ADS-ADX combination for your vehicle
- Go to Tools … Preferences and select “Use Plug-in” for Interface type. Then make sure “TunerPro Data Acquisition I/O Interface” is selected. Next, select “Configure Plug-in Component” Then make sure “Standard Serial” is selected and the COM port shown matches the COM port of your cable.
- Finally, click the “Test For Valid Interface Using Settings” to perform a test on the cable.
If your cable fails the above test, it will almost certainly need to come back to us for repair. If it passes the above test, the hardware has passed a basic minimal test.

Do you have a GM vehicle between 1980 to 1995? If so, there is a big chance your car has an OBD1 connector (ALDL).
This connector is unique and applies to Pontiac, Chevrolet, GMC, Oldsmobile, Cadillac, and Buick, and more. The positive thing with the OBD1 connector is you can read your trouble codes at home without any diagnostic tools.
There are special diagnostics tools for this kind of connector, but they are not necessary as you can read them just as well without a tool.
If you have a newer car after 1996, you have OBD2 codes in your vehicle and this article will not apply to your car. You can check our other article with OBD2 codes.

OBD1 Connector Location
The OBD1 connector is usually located under your steering wheel, under the dash. The connector may have a black plastic cover, which you have to remove before accessing it. The connector is often black and has 12 pins on it; pretty easy to identify.
Check the image above to see what an OBD1 connector looks like
OBD1 Connector Wirings Pinout
The OBD1 connector has 12 pins, but not all of them are used in most car models. The standard pins like the ground, power, and a diagnostic pin are the same in most car models though.
Make sure you connect your wires correctly, as if you are not careful, it may damage your vehicle’s electrical system and control units, which can be very expensive.
This is how the pinout of the OBD1 connector looks like in most car models, check your repair manual for the exact pinout:
- A = Ground
- B = Diagnosis Terminal
- C = A.I.R
- D = Service engine soon light
- E = Serial Data
- F = T.C.C
- G = Fuel pump
- H = Brake Speed input
- J = None
- K = None
- L = None
- M = Serial Data

How to Read OBD1 Codes at Home
Our reading method without a diagnostic tool is to make short the circuit of pin A and pin B. The car will then enter the diagnostic mode and flash the “check engine Light” several times, and we should count the flashes to figure out the diagnostic codes.
How to read the OBD1 codes:
- Always connect a car battery charger to your car when doing any electrical work that requires the ignition to be on. Low voltage can cause a lot of trouble with the troubleshooting and many error codes that we do not want.
- Put a jumper wire between PIN A and PIN B.
- Let the jumper wire sit there and turn the ignition to ON. Do not start the engine.
- The check engine light will begin to flash. Count the flashes. There will be a longer pause between the codes if you have several trouble codes and a shorter pause between the trouble codes’ digits. For example, code 16 = 1 flash * Pause * 6 flashes.
- When all trouble codes are outputted, it will flash the code 12 – 1 flash * Pause * 2 flashes.
- Write down all the trouble code numbers you got and check the trouble code table further down in the article.
- Remove the jumper wire and car battery charger.
OBD1 Code Reader
There are also a lot of OBD1 code readers on the market to make the job easier. With an OBD1 code scanner, you do not have to short the connector, and you do not have to count the flashes on the dashboard.
You will get the problem in clear text on your device, and this is, of course, a great investment to make if you are reading a lot of trouble codes from older vehicles.
There are several different code scanners on the market in all different price ranges. Some scanners can read both OBD1 and OBD2 codes, but these are pretty expensive. One really affordable scanner that I found is the Innova 3123. You have two different options, Ford or GM vehicles, you can choose from. If you want to take a further look at the scanner, you can find it here on Amazon:
