Thread: Diagnostic plug under panel near left drivers knee?

I'm not sure which plug you are referring to under the kick panel?

The OBD2/J1962 connector under the left black plastic is the one that you connect the diagnostic equipment to.

So I presume if I got a reader it should work?
I had both the Dealer and an aftermarket Rover shop pull the kick panel off and connect diagnostic stuff to a plug in there. Hence the Question.

I've never done it, but RAVE says that is the plug for the T4 diagnostic equipment, the OBD2 one.

Anyone actually done it?

That plug near your left knee is OBD11. I have used it to clear faults with my ABS.

Strictly speaking that is not possible. OBDII refers to engine diagnostics so you cannot clear ABS faults with an OBDII connection.

However, the socket may be an SAE J1962 connector.

I don't recall seeing that connector in my D1.

Ron,
It is definitely OBD11 and you can clear ABS faults, I have done it.

Hiya all, i hope you don't mind me adding my tuppence worth to the conversation.

The commonly referred to as "OBDII Connector" itself is designed under the SAE J1962 standard which is incorporated as part of the Later OBDII standard. There is now even a designated 24Volt variant

Technically although a 16 pin connector, it needs only a couple of pins or so to facilitate connection to the Engine management and Auto Box using one of the incorporated OBDII communication standards and nothing more, as only access to some diagnostic capability of these ECU's is legislated. This is the part that your typical OBDII scan tools can access. The other pins are free for use as desired by any vehicle manufacturer.

In some LR's they may have this connector fitted, but comms with ECU's such as the ABS, Airbag or EAS is facilitated using other connectors also fitted in the vehicle using an entirely custom and secret to LR only communication protocol that is certainly part of no published standard.

In others however the other ECU's are connected to the same connector although they still use secret communication protocols. In fact some anti access features are added to stop any Tom Dick or Harry from doing that.

Some companies such as ours have however managed to reverse engineer and understand these secret communication protocols and have for some time been supplying equipment capable of connecting and communicating with them regardless of weather they use a seperate connector or the J1962 OBDII connector. There are now a few around

But it is important to note that these other vehicle systems are not OBDII complient, they do not follow any standard and cannot be communicated with using any generic OBDII equipment regardless of if they also use the J1962 connector or not. Even the engine management still has a lot of info that cannot be accessed using a generic OBDII scan tool.

This is why there is always such a big price difference between Generic OBDII scan tool equipment and that which can access the other ECU's
Because an OBDII scan tool requires no reverse engineering to make, but a system that can access all other ECU's does.

I hope i have been able to help clarify a few mis conceptions etc.

warmest regards

Colin

Go back and re-read what I said. Also read what Colin wrote under your post.
