Default disabling F45 with tech 2

Hi All,
I am having a local shop disable my 2001 F45 Ride Control with a Tech 2 but the tech is not familiar with the procedure. From what I've read is it... disconnect the 2 plugs from the ESC, key to ON, deselect F45 with the Tech 2, Key OFF, wait 15 seconds, then key ON and messages from my DIC gone ?????????

Thanks,
Bob

Posted here previously.

Here are the steps that must be followed to delete either F45 or F55:

1. Hook up your Tech 2 (Driver's footwell), turn the car ON, make sure the module in the left rear storage compartment (pull back the velcro lining on the front of the compartment) is plugged in. DO NOT UNPLUG THIS MODULE

2. Now use the Tech 2 to delete the F45 option ( F55 option does not appear on the Tech 2 menu screen - SO - DELETE THE F45 OPTION
(use the screen captures - steps 2-14)

3. Save the new configuration

4. DO NOT TURN THE CAR OFF DO NOT REMOVE THE TECH 2 Go to the module in the rear of the car, unplug the GRAY connector - IT IS THE WIDEST ONE - leave the other 1 (F/45) or 2 (F/55) plugged in.

5. Turn off the car but LEAVE THE TECH 2 PLUGGED IN

6. Remove remaining plugs from module in the rear of the car - Never plug them back in again, if you do the F/45 turns on automatically.

7. Now the moment of TRUTH - Turn the car on and verify that the dreaded - MAX SPEED 80 MPH - is gone. This message was only present if you had already disconnected the shock sensors. Some people have had to disconnect their battery to allow the computer to reset to remove this message, but I would confirm with the Tech II that the F/45 was actually deleted first and if not reconnect everything and start again with step 1.

8. Unplug the Tech 2 - Get in the car and take it for a ride. Smile as you pass the DREADED 80 MPH.
