Firmware notes
OEM Touch Screen: The Comfort Convenience Controls, Heated Seats Activation feature and Rear Window Defogger Activation
feature, will only function if the vehicle is equipped with OEM touchscreen radio package.
Remote Start features: The following remote start features can be configured via the information display:
• All Locks (must also set during module flashing)
• Driver Priority Locks (must also set during module flashing)
Remote Start Ready (RSR) installations are not compatible with vehicles equipped with a manual transmission.
Remote Start Ready (RSR) is a function that enables the interface module to remote start the vehicle completely on its own.
Consequently, there is no need for an aftermarket or an OEM remote starter in order to start the vehicle from a distance.
The optional Plug & Play THCHD3 Rev. 2 T-Harnesses are sold separately
SmartStart Compatible: SmartStart is equipped with D2D, which means it can be connected to an interface module and used in
Remote Start Ready (RSR) mode without the use of a remote starter. See "Module programming" for more information.
Unless specified otherwise, all connectors are displayed from the wire side, with the exception of the OBDII diagnostic connector.
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.
