Overview

The 0112 module is used in select Kia and Hyundai vehicles and is built around the MAC7242 microcontroller platform. This ECU is part of the vehicle’s SRS (Supplemental Restraint System) and plays a critical role in airbag deployment during an accident.

After a crash event, the ECU stores crash data, which disables further airbag operation until the module is reset. GromCalcTool offers a secure, fast, and non-invasive method to clear crash data via CAN BUS without requiring chip removal or soldering.
