We're your resistors purchased OTC, or did they come in a "delete kit"?

Did you use the DIC to check for any RTD codes?

Agree. OPs thread says F45. Resistors work on F45, and on the '03. The '04s, according to Lyle@C&S Corvettes, have no way of tuning out or using resistors to fool the BCM. Lyle told me the '04s can only be fixed by replacing the OEM shocks with OEM, $600-$700 (each!) shocks. If anyone knows different, please post up. C&S is usually spot on.....

On second thought, I believe Lyle did say the '03 requires the Tech II, not the resistors. The '04s, however, have no workaround I'm aware of, except buying new $700 shocks (each).

The way GM, and probably all manufacturers are today, they probably set up the BCM to ensure that there's no workaround; the owners of the '04s have to start buying some of those overstocked expensive shocks! Don't know the exact cost of the shocks, but a good guess would be at least $600 each×4=$2,400+tax!!!!
