Introduction

The ECO-PCM or ECO-V2 OBD programmer are used to program save last mode for Mercedes Benz vehicles with auto start/stop.

Once programmed, the vehicle will save the last setting for the start/stop eco mode.

For example, if the start/stop eco mode is left in the off position before shutting off the vehicle, the eco start/stop will be in the off setting the next time the vehicle is started.

Note: the OBD programmer is for use in 1 vehicle. Once the programmer is used, it can only be used in the same vehicle.

Attention: The OBD programmer should be removed after use. Do not start engine or drive vehicle with OBD programmer installed.
