OBD port location.

[Paul H Johnson]

Hi everyone. Some advice please. Can someone please tell me what the 3 identical obd ports in the engine bay are fo ? The single one on the left is, I believe, the reset. What are the 2 on the right, next to the fuse board?
Thanks in advance for any info.

The one on the left is the 20 pin "Pacman" port for car diagnostics. The 2 on the right are for engine/transmission looms etc. They may or may not be used depending on the spec of your car.

If your car is a later model, you'll also have the OBD2 port under the steering wheel.

If you have the OBD2 port under the dash it only "talks" to the engine and Auto Gearbox ECUs. For the rest you need to connect to the 20 pin connector under the bonnet.
