Engineering Menus

On my 2014 GC Diesel, I have used the "hidden" Engineering Menu on the 8.4AN by pressing the left hot & cold buttons together for 5 seconds.
That works fine.

Question: somewhere I heard or read that there is ANOTHER hidden menu. Does anyone know about that and how to access it?
Cheers

Try this
Hold the 3 buttons at the same time. UP DOWN temp control driver side and Windshield defrost. I've been there but i don't remember whats inside. Not much you can do anyway.

Re: Engineering Menus

Since all these systems now have Bluetooth and Wifi, it would be really nice if you could hit some button combination and print out a "health report" that would show pass/fail on all sensors and components, error codes as well as software versions and update histories. Plus, it could show upcoming maintenance due as well as current levels for fluids, air pressure, etc.

I can do similar tests with my satellite receiver, computers and tablets, phone, TV and even the printer itself. This is just another computer. It would be helpful to both the customer and the dealer to be able to access an easy to read report like that.

Re: Engineering Menus

Another idea buzzing in my head is this.
If the onboard computers can sense all of the OBD-II problems & codes etc, why can't they simply build an OBD-II code reader into it and display the whole works on the 8.4AN screen. That would save me forever plugging mine in under the dash.

To be honest, the answer to both of what we posted is this:

Car makers want the vehicle owners to be ignorant. An ignorant customer is a profitable customer.

When customers have knowledge, the don't rely on the dealer to tell them what needs to be done or what a fair price is.

I think the only way we'll get what we're asking for is with legislation similar to that pertaining to our medical records. We need a "right to know" law for our vehicles.

I had that feature on my '98 Corvette. You go into the menu and run a diagnostic and any trouble codes would be displayed in the DIC on the instrument panel.
