Start off by disconnecting the battery and the body module. Add a small amount of stabilant 22 or dielectric lube to the pins and reconnect it. This may correct the problem. You may have to do the same to the engine control module.

If you need assistance with these checks, feel free to contact a certified mechanic who can diagnose your electrical issue and make the necessary repairs to your vehicle.
