Fuel Level Sensor 1 - Circuit Short To Ground
Description
The Body Control Module (BCM) provides a switched reference voltage on the fuel level signal circuit through a pull-up resistor that is connected to battery voltage. The BCM monitors the voltage on the fuel level signal circuit. The fuel level signal is adjusted for changes in battery voltage. The voltage value is then transmitted as a network message on the communication network.
