Firmware notes

Limitation! The unlock commands from the aftermarket remote control or SmartStart mobile application will only work while the

vehicle is remote started. When the vehicle is not remote started, the OEM remote control must be used to unlock the vehicle.

Handbrake Status connection is mandatory.

Smart door handles: Not functional during runtime.

Transponder override: This firmware does not support transponder override. One (1) programmed OEM key must be wired into the

vehicle to complete the installation of a remote starter.

Climate controls: Porsche climate controls are key memory sensitive. This means that the last key used to operate the vehicle will

determine the setting for the climate controls. In order to make changes to environment control settings, the following procedure is

necessary:

1) Remote start the vehicle.

2) Make your climate control adjustments, ensuring not to use the AUTO mode on the control panel as this

makes the Porsche adjust its HVAC settings based on external factors such as engine temperature.

3) When the adjustments are complete, turn off the vehicle starter, either by remote or footbrake.

Remote Start: To remote start the engine, the hood, the hatch and all doors must be closed.

Remote Starter menu feature "Diesel Start Delay":

•This feature must be set to Wait to Start for a minimum of eight seconds for both gas or diesel vehicles to be remote

started successfully.

•Parking Lights Output must be set to Pulse for proper operation.

Unless specified otherwise, all connectors are displayed from the wire side.

Refer to the Vehicle connections following the installation diagram.

Footnotes

[1] Hood pin: The installation of an aftermarket hood pin is only required on vehicles that are not equipped with a factory hood pin, or if

not supported in data

[2] Tach wire: Optional connection required on some remote starters, which do not support a tach signal in D2D.

[3] Correct brake: The correct brake activation wire will test as 0.6V with the ignition on and 12V with the brake pedal depressed with

ignition on. Failure to identify the correct wire will cause permanent damage to the interface.
