Line lock and launch control DNF

[Whipple Bullitt]

Bought a used low mileage 2019 Bullitt in 2021. Drove it for a couple times and then dropped it off for a whipple install. Only drive it a couple times a summer but it is usually on a bit of a road trip. Finally getting into driving it a bit more. Wanted to take it to the local street legal night. In preparation found a quiet stretch of backroad to try out the track pack goodies. Couldn’t get LC or the LL to function. Stopped by the install place to see what was up. They checked out everything mech and all seemed good. Put a scanner on it and found a code that they cleared . Took it out in the lot to test, and LL worked once. Rescanning indicated another code. Cleared it and LC worked once.
Was told the solution would be to have the pins all metered in the harness to find where the bad voltage was triggering the codes. Anyone else deal with this before?

What code?

Was it the same code or a different one that came up after the line lock worked once?

Wasn’t given that info, other than they were two different ones. Stopped in unannounced on my way thru, not a proper appt. And know that a simple OB2 scanner won’t detect them, or the Tomahawk tool that came with the tune.

Without knowing the codes, you are just chasing your tail. You need to know if the codes were related to a particular system or component, or if they were totally independent of each other. Could be as simple as a bad ground, or connection that the shop who did your Whipple install overlooked
