Introduction

ATTENTION:

  • IF YOU ARE INSTALLING THIS SYSTEM ON A GASOLINE SPRINTER, PLEASE MAKE SURE THAT THE SOFTWARE VERSION IS V5.23 OR ABOVE
  • IF YOU ARE INSTALLING THIS SYSTEM ON A 2023 SPRINTER, PLEASE MAKE SURE THE SOFTWARE VERSION IS V5.25 OR ABOVE

The SKSNG907 is a remote start and alarm kit for the 2019-2023 Mercedes & Freightliner Sprinter (907)

Link to product here.

Out of the box, the remote start will work using the factory key fob (lock-unlock-lock). It will also include

OEM style alarm with no additional hardware. A Compustar DAS sensor can be plugged in to add shock/tilt/vehicle movement protection to the alarm. The alarm will use the factory horn and flash the parking lights. In addition, a full Compustar or Directed external alarm can be added.

For extended range, the Compustar Drone and Directed Smart Start can be added and will provide 2-way communication (including alarm notifications). All Compustar RF kits are compatible with the system and any Directed RF kit using an XL202 (XL202 not needed if using Directed external alarm).

The remote start & alarm installation for the SKSNG907 or SKSNG907RV is 100% plug & play to the vehicle and requires the following steps:

  • T-harness connection at PCM module
  • T-harness connection at EIS module
  • Key box installation
  • Hood pin installation

There is also a kit (SKSNG907RV) that also includes OEM style high idle and an optional external trigger for start / stop. Link to that product here.

  34. The SKSNG907RV includes an analog start/stop trigger to operate the remote start from an external trigger. The cable has a white 4 pin plug and, if using external start/stop triggers, will plug into the white or green 4 pin plug labeled Trigger Input on the module labeled SKSPCM. Refer to this diagram for wiring. The trigger has 2 configurations, 1 wire or 2 wire. The 1 wire configuration (default) will start the engine when the start wire is grounded (green). The 2 wire configuration has a separate start wire (green) and stop wire (white). In the 2 wire configuration, a momentary ground on the start/stop wires will execute the command

    • The 1 wire configuration is the default setting. To change to the 2 wire configuration, you can use the SmartKey Starter® menu. The trigger configuration is in a hidden menu. For instructions getting into the hidden menu, please contact Mid City Engineering at 312-421-1114 or sales@midcityengineering.com

    • Note: when using this auto start with external 1-wire trigger (latched ground to start and run) the system will re-start if ground is still applied to start wire after run-time expiration. The system will continue running and re-starting until external trigger removes ground signal. 

    • For Sprinters without the volume and mute buttons on the steering wheel, if the SmartKey Starter firmware is below V5.25, you will need to use a USB programming tool to change this setting

    • If analog input(s) not being used, the 4 pin white input cable should not be plugged into the SKSPCM module.

    • Be sure to insulate all wires not used on the cable.
