What are DLCs?
Diagnostic Link Connectors (DLCs) allow the Code Scanner or Scan Tool to communicate or "plug into" your vehicle's computer(s). Before OBD II was enforced, manufacturers used different data link connectors to communicate with the vehicles. The proper cable must be used to connect the tool to the vehicle's DLC. The vehicle's DLC may be found in several different places and have many different configurations depending on the make and model. Check for the necessary DLC and its location in pre-OBD II (1995 and older) domestic vehicles:
- Chrysler (1989 -1995)
- Ford and Lincoln/Mercury (1984 -1995)
- GM (1981 - 1995)
All OBD II (1996 and newer) vehicles are required to have a 16-pin "D" shaped diagnostic link connector located on the driver's side and under the dash near the steering wheel.
