Bay Area Tech 2 help.
Anyone in the bay area have a tech 2 and want to help me erase my mag ride suspension from the bcm. Installing the z06 shocks because at least one of the mag ride shocks is leaking.
Thanks!
Thanks!

To delete F/45 you have 3 options: 1. spend $200+ or - on simulator plug-ins to go in the shock sensor
plugs. 2. Install 10W 10 Ohm wire wound resistors (from Radioshack) into the shock sensor wire's. 3.
Program it out with a Tech II and disconnect the ride control module.
To delete F/55 your only option is the Tech II delete - resistors will not work.
Using the sims or the resistors assumes that all the other components in the system (sensors, modules
and wiring harness) are operating correctly and if something breaks you will have to fix it or get codes. In
my case I had a very annoying intermittent code from a wheel position sensor that was due to a short in
the wiring harness in an unreachable location. I elected to go the Tech II route as it was so easy, cheap
and imo the most complete solution.
The hardest part is finding a Tech II - all GM dealers have them but they may hesitate at the programing
or want to overcharge you ($125 at mine). Just start calling local shops and if they don't have one ask
them if they know who does - it only took me 2 calls to get a referral to a shop that had one. Don't bother
if they tell you they have a different scantool that will work - it won't, it must be a GM Tech II. Try a shop
that specializes in Cadillac repair, that's what I used and it turns out they had been programming out
selective ride from certain Caddy's for years because the replacement shocks are $1300 each (I guess the
Caddy tax is higher than the Vette tax) and knew exactly what I wanted to do.
Go to this link http://www.stopforce.com/RPO.html and print out steps 2-14. Those are the instructions on
what to do with the Tech II.
Then copy and print these procedure sequence instructions:
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
*NOTE from Zoxxo : A correction is needed here. The F55 module on the C6 is not in the rear of the car.
It's under the right front fender liner. The service manual (at least the ones I have - 2006 & 2007 - were
never updated from what the C5 manuals said. F45 was the C5 version of F55 (and even that transitioned
to "F55" the last year of the C5.)
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)
Step 2: Startup TECH2
Step 3: Enter Diagnostics menu
Step4: Enter year of car
Step5: Enter Passenger Car menu
Step 6: Select Body from the menu
Step 7: Select Y body from menu
Step 8: Select body style from menu (Coupe/Sedan is FRC/ZO6)
Step 9: Select transmission type
Step 10: Enter body control module menu for adding/deleting option codes such as automatic headlamps,F45 suspension. If your
interested in adding the tire pressure monitoring system please skip to Step 15 below.
Step 11: Enter Special Functions menu
Step 12: Enter BCM RPO Reprogram
Step 13: Enter cars country of origin
Step 14: Toggle functions on and off. The asterisk next to the option code indicates this function has been turned on. Note that the
Automatic and Manual HVAC controls are both turned on. This is normal and should be ignored. Go ahead and hit the save option
button when your done and power off the TECH2.
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.
With these instructions in their hands even the most inexperienced tech can do this. It took mine 5
minutes and they charged me $25. I would have spent much more time and effort getting and installing
resistors.
If you haven't already changed your shocks drive home carefully as the shocks become very soft, not
dangerous but as GM advises keep it under 80MPH.
Hope this helps somebody else.
