This details out what exactly is needed to add/change RPO option codes to existing 97+ Corvettes using GM Tech2 diagnostic scan tool.
This Tech II scanner can be purchased from obdii365.com for around $300. This is helpful on 2001+ ZO6s to add the T82 Automatic Headlamp operation at night feature as well as adding the tire pressure monitoring function. Both of which are built into the ZO6s Body Control Module (BCM) and just need to be “turned on” in order to work. The Automatic headlamp function usually requires no parts to be purchased but the tire pressure monitoring system needs to have sensors installed on all 4 tires. These can be found in the classified section of corvetteforum.com usually for around $200.00. These instructions will also help owners of F45 real time dampening suspension option convert to regular shocks that do not 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 function and toggle off the F45 suspension options. No codes will be set and the car will not go into reduced engine power mode.
