Nowadays, the passenger cars are employing more and more electronic devices for controlling various mechanisms. This has increased the demand for such equipments in the passenger car. The electronic devices for controlling the mechanisms such as keyless entry, window, wiper controllers, mirror controls, engine performance monitors, security systems, lighting control are mounted on Printed Circuit board (PCB) which is enclosed inside the plastic cover assembly called Body Control Module (BCM). The BCM is attached inside the dashboard assembly which is subjected to various loading conditions. In addition, space and height constraints should also be taken into consideration. In present work, dynamic analysis of existing design of BCM is carried out. It has been observed that, the existing design fails under impact loading condition. To overcome the failure, modifications in design are proposed. The modified design of BCM has been tested through both, numerical simulations and experiments. Further, modified design of BCM has been tested for vibration loading and mechanical shock condition using numerical simulation. The results show that the component is safe under these loading conditions.
