Reducing adverse effects of electromagnetic interference in a vehicle

A method for manufacturing a vehicle, comprising:

• installing a first communication device in a chassis of the vehicle, the first communication device having a first ground;
• installing a second communication device in the chassis, the second communication device having a second ground;
• connecting a first end of a shielded cable to the first communication device, the first communication device being configured to electrically couple a shield of the shielded cable to the first ground when the shielded cable is connected to the first communication device;
• connecting a second end of the shielded cable to the second communication device, the second communication device being configured to electrically couple the shield of the shielded cable to the second ground when the shielded cable is connected to the second communication device;
• electrically connecting a first end of a first wire to the first ground of the first communication device;
• electrically connecting a second end of the first wire to the chassis at a first point;
• electrically connecting a first end of a second wire to the second ground of the second communication device;
• and
• electrically connecting a second end of the second wire to the chassis proximate to the first point to mitigate effects of electromagnetic interference (EMI) on the communication system.

A communication system for use in a vehicle, comprising:

• a first communication device configured for operation in the vehicle, the first communication device having a first ground;
• a second communication device configured for operation in the vehicle, the second communication device having a second ground;
• a shielded cable that communicatively connects the first communication device and the second communication device, the shielded cable having i) a signal wire that is electrically connected to the first communication device and the second communication device, and ii) a shield that is electrically coupled to the first ground and the second ground, wherein the first communication device is configured to couple the shield of the cable to the first ground via one or more first capacitors to mitigate effects of electromagnetic interference (EMI) on the communication system;
• a first wire having i) a first end electrically connected to the first ground and ii) a second end electrically connected to a chassis of the vehicle at a first point;
• and
• a second wire having i) a first end electrically connected to the second ground and ii) a second end electrically connected to the chassis proximate a second point different than the first point.
