OBD Scan Tools For ALDL or OBD1 Cars
Are you looking for ways to diagnose an ALDL or OBD1 car? In this page, we'll provide some information on how you can do that. But, before we go into that, there are some facts you need to know.
What's the difference between OBD2 car compared to an ALDL or OBD1 car?
Unlike the standardised Onboard Diagnostics II (OBD-II), cars with earlier OEM-specific ALDL or OBD1 systems use manufacturers’ specific communication protocols. This means that connectors, pin locations, error codes and bus-communications varied considerably from one manufacturer to another.
Also such systems are limited in quality, quantity and speed of reported data. For example, OBD1 cars can report up to 300 data parameters (PID’s) compared to 15,000 possible data parameters for OBD2 cars. So, the type of data reported by OBD1 is not suitable if you’re after monitoring real-time gauges or diagnosing a complex DTC! To give you an idea, here’s a sample of the data stored and transmitted through the OBD1 interface:
- Catalyst converter system and alert below 60-percent efficiency
- Engine missfire monitoring
- Evaporation emissions system
- Secondary Air Injection (AIR) system
- Air Conditioning System
- Excess Fuel Trimming
- Oxygen Sensor Performance
- EGR System
As trackable data, stored codes and their definitions varied between car makers; diagnosing an OBD1 car is not as easy as diagnosing an OBD2 car. In order to diagnose an ALDL or OBD1 car; you would require a special scan tool that could adapt to myriad connector type as well as different data sets.
Here are some ways to diagnose your ALDL or OBD1 Car
Buy ALDL or OBD1 Diagnostics Scan Tool
Luckily, it's now possible to diagnose some ALDL or OBD1 compatible cars with an affordable diagnostic code readers. Instead of getting an expensive scan tool with price range of $3-15,000, some of our single car scan tools like the CARECAR Scan Tools and FOXWELL scan tools offer a great and affordable way to diagnose some OBD1 cars.
If your car uses the older OBD1 protocol and it's among the list provided in the table below, then you can use FOXWELL scan tools to diagnose, read and clear trouble codes from your car.
- Mercedes Benz & Sprinter
- GM General Motors
- Toyota (17 pins and 22 pins)
Buy a PC-based ALDL or OBD1 Diagnostics Software
The other option is to buy a suitable software such as TOAD OBD Software. You just need to download it on your PC and connect it with your car through special the 12-pin or 16-pin ALDL cable. If your car has a special OBD1 plug shape, then you’ll also need to get an extension cable and plug it with the ALDL cable. Even for OBD2 cars, TOAD offers a complete all-in-one package that will let you perform powerful and thorough health and performance checks on your car. It extracts 50-90% more fault codes and critical operations data then Android/IOS apps or generic hand-held scan tools.
Before you buy TOAD, make sure it does work with your car. To read more or purchase TOAD Click Here

1999 BH Subaru OutbackBy: Mark on 21 December 2017Bought an OBD2 scan tool to work with Bluetooth Android app. Apparently my 1999 BH 2.5 litre Subaru Outback is an OBD1. Can I buy an adapter cable to plug in to the OBD2 scan tool to find faults? If so what cable and plug do you recommend and will it be compatible with the current program app or what program would be used to run diagnostic checks? Thanks. Mark
Unfortunately the wifi/ bluetooth scanners only work with OBD2 vehicles no matter the app or cable adapter. For 1999 Outback we recommend iLink400 or AETR-SBR.
