The next step of technician is to take a look at the ground wire that runs from the door chime module connector to the chassis ground.

An electrical connection between various metallic components of a machine is ensured by a chassis ground, which connects them all. A couple such examples include automobiles and electrical devices. As with lightning protection for high voltage power systems, chassis grounding provides the same function for electronics. To avoid damaging or interrupting circuit functionality, it is specifically necessary to direct undesired and potentially harmful current away from system parts and components. An electrical device's metal housing serves as the chassis ground, which is a site where ground is collected. To prevent electrical shock, a chassis ground can be utilized for grounding and shielding. Using a strong ground wire or cable, ground the engine block to the frame, ensuring sure that the connections are metal to metal, clean, and secure.
