Reported Problem: New Prestige Z Series Install. Negative parking brake input connection good. Turbo-timer turned ON and set for 3 minutes in programming but the turbo cool-down mode will not activate.
Possible Fix: This feature must be activated after installation is completed. This is only required the first time the turbo timer is needed. After activation the system will always automatically enter turbo timer mode when the parking brake is activated: With the vehicles engine running for more than 15 seconds: Activate Parking Brake: Press the programming button on the antenna 2X: The parking lights will flash 2X to indicate turbo timer mode has been activated.
