Question: Is it possible to use Yanhua ACDP2 to correct mileage for the MB HU6 instrument module (IC77) with R7F701403 chip on Bench?
OBDExpress.co.uk engineer replied:
Yes. Previously, only OBD mode was available. Now Bench mode is supported as well.
Requirement:
- Yanhua Mini ACDP-1/Mini ACDP-2
- Yanhua Module 37 with License A103
- Yanhua Mercedes-Benz MB HU6 YH-OBD Platform (newly released)
Highlight: you don’t need to install the original HU6 module on the car and operate via OBD on car. You can connect HU6 Module to MB HU6 YH-OBD platform to operate mileage correction on the bench.
MB HU6 vehicle models supported:
- Mercedes-Benz W247 A/B/CLA/GLA/GLB after 2019
- Mercedes-Benz W177 CLA/GLA after 2019
- Mercedes-Benz 167 GLE/GLS after 2019
