Introduction

There are two modules which need to be installed:

  • OBD programmer module. This module should be removed after programming
  • CAN interface connected on passenger side using T-harness. Power and ground for this module can be connected to fuse box using provide Mercedes connector and ground bolt near door opening using provided ring terminal.

The high idle can be used with or without an on/off switch. A negative trigger input (purple wire) is provided to use for a switch. For high idle turn on, the purple wire must be grounded, the vehicle must be in park, and the parking brake must be engaged.

  • If you are using a switch to activate the high idle, connect the switch to the purple wire and chassis ground
  • If you are not using a switch to activate high idle, connect the purple wire directly to chassis ground

    • There is an LED inside the OBD programmer case that will illuminate when it is plugged in. Once programming is complete, the LED will turn off

    • If LED begins to flash, the programmer has already been used and locked to another VIN. The OBD programmer is a 1 vehicle use programmer. Once used on a vehicle, it is locked to the VIN. The programmer can be used to program the same vehicle multiple times.
