11.
With Unlocked PCM installed, connect TD2 to Vehicle.

c.
Tuner will read PCM and continue tuning your vehicle. You will need to follow device screen prompts from this
point forward.**
(When prompted for Ignition ON, be sure double tap on push start and check to see
“run” illuminated on push start itself)
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 not abnormal and part of the process.
When you begin to tune and are prompted to turn the “Ignition On”, 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.
After installing your tune, 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
