How to change RPO F45 option codes to Corvette’ with TECH 2

This details out what exactly is needed to add/change RPO option codes to existing 1997+ Corvette’s, using a Tech 2 scan tool.

These instructions will also help owners of F45 real time dampening suspension option convert to regular shocks that don’t have sensors built in. Right now people are paying upwards of $200.00 for emulators that plug into the wiring harness to trick the BCM. A simple solution is to just go into the BCM’s function and toggle off the F45 suspension options. No codes will be set and the car will not go into reduced engine power mode.

Defrost vent:

11-1 11-2

Step 1: Obtain a working TECH2 (original or HQ clone- both ok)


note: Tech 2 knockoff has many types and here is a chart for you to know all.


Step 3: Enter Diagnostics menu


Step 4: Enter year of car


Step 5: Enter Passenger Car menu


Step 6: Select Body from the menu


Step 7: Select Y body from menu

Step 8: Select Y body from menu


Step 9: Select transmission type


Step 10: Enter body control module menu for adding/deleting option codes such as automatic headlamps,F45 suspension.


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 you’re done and power off the Best obd2 scanner TECH2.

Note: If your vehicle was built after Feb 02 you may or may not have the sensor installed from the factory required to make the T82 automatic headlamp function by simply turning it on in the cars BCM. A quick way to verify this is to remove (no tools required) the defroster vent on the center of your dash. There should be 2 sensors installed. The sensor on the right is for your climate control and the sensor on the left is for the T82 automatic headlamp control. If this sensor is not present it can be purchased from GM for about $12.00. The part number is 12450121 and it simply snaps into a space already provided on the defroster grill.

Next you need to find the pigtail that plugs into the sensor. It is on the right side of the steering column and has a piece of white tape holding it folded in half. Cut or tear the tape and leave it dangling down.

Now, take a metal clothes hanger, and stick it down through the defroster hole in the dash. You will see a little 1 inch by 1/4 inch slit to slide the hanger through, then force it to the floor. Tape the pigtail to the hanger and pull it back up through the hole in the dash. Then plug it in to the sensor, snap the grill back in and you are done.

Have fun!

GM Tech2 VS MDI for GM (item SP163)

Tech2 is the most cost-effective one, for it is with reasonable price and covering not only For GM vehicles, but also For SAAB,For OPEL,For SUZUKI,For ISUZU and as well as For Holden.
Besides, it is with authentic For GM software and support on-board diagnostics on all gm systems. If you want to use it to do For GM car programming, you should buy tis2000 software.
One disadvantage is that tech2 remains an basic or essential gm diagnostic tool for vehicles before 2010.

For GM MDI is used to serve vehicles with auxiliary CAN bus that cannot be served by tech2. Actually, thisCar Diagnostic Tool is working with vehicles after 2010 and covering newer models than that of Tech2.
Its highlights are with faster reprogramming (increased about 20-70%), serving exclusive new models, and more economical. This is a good investment for future vehicles models.

How to disable GM, SAAB DRL with Tech2

Many people want to disable the day running light for fuel economy or other reasons, me included. Here I have figured out a simple way to reset it completely on my 1999 GM and my daughters 2004 SAAB with GM Tech2 scanner from my friend. This takes about 5 minutes from start to finish and will completely disable your automatic headlights so they will never come on. But all of the lights will function correctly. They just would not be automatic anymore.
Tools you will need:
GM Tech2 scanner for GM and SAAB
32MB PCMCIA Card for Tech2
A SAAB car (Here take my daughters 2004 SAAB for example)

How to:
1. Insert 32MB card into Tech2
2. Run Tech2 diagnostic tool
3. Go to Diagnostic Mode
4. Select Diag >2003 >9-3 Sport Select Body>Exterior Lighting and Horn
5. Low beam adjustments, F0. Auto Low Beam also in Pos 0
6. Change setting to NO
7. Wait several seconds until the lights flicker and go out
8. Exit
9. Go to Fog Lights Front
10. Change to Position 1 & 2 ROW (Rest of World) Program and Exit

This will give you:
Pos 0 > No Lights
Pos 1 > Fogs and 5 Watt Headlamp / Parking Light
Pos 3 > Low Beam, High Beam, Manual Control of Fogs
