General Motors 12 Pin OBD1 - 16 Pin OBD2

OBD stands for On-Board Diagnostics. It is a standardized system built into cars and other vehicles to monitor the status of various vehicle systems. When a problem is detected, the OBD system generates an error code that can be read with an appropriate diagnostic device.

The GM 12-pin OBD1 cable allows you to read these error codes and understand what is wrong with your vehicle. This can help you identify and fix problems, or determine when professional service is needed. It can also be used to monitor certain vehicle parameters, such as engine load, rpm, vehicle speed and more.

It is important to note that although the GM 12-pin OBD1 cable can be used to connect to your car's OBD system, you will also need a suitable diagnostic device to read and interpret the fault codes.

Advantages & drawbacks
  • Using this adapter cable, you can also use a compatible reader to read an older GM before 2001.
  • Rugged materials for endless use
  • Works only with readers that also support the OBD1 protocol
