Abrites MN037 – Cluster Calibration IC177

• Enables adjusting the mileage value stored in the IC177 instrument cluster (without needing the EZS/EIS module present).

• Blocks synchronization of mileage with the EZS module so the adjusted value stays independent.

It’s essentially a cluster calibration tool for Mercedes vehicles equipped with the IC177 digital dashboard.

Notes & Safety

• The procedure is done on the bench, on the cluster module itself, not via the vehicle’s OBD port.

• Working directly with the IC177 PCB requires technical skill in electronics and soldering. Abrites does not assume responsibility for damage if the mandatory adapter isn’t used correctly.

• AVDI with active Annual Maintenance Subscription (AMS) is required for use.
