*On first power up with an Unlocked PCM the cluster panel will illuminate the red security light and may warn about
other module errors (Traction Control, ABS, etc.). This is expected and part of the process.
**At this point, the cluster panel should no longer have the red security light illuminated which signals that your JL has
been programmed, and connected to, the Unlocked PCM.
**Before pressing “OK” on your F5, Start the Vehicle. Let the Vehicle Run for more than 3 seconds, and test throttle
response. The vehicle shutting off after ~3 seconds, or having a dead pedal indicates that there was an issue reading
stock data and/or writing stock data to Unlocked PCM. If throttle response is good and vehicle stays running, please
continue by shutting off engine, returning ignition to ON, and pressing “OK” on F5.
