Seatbelt Beacon Relay
Illustration 4 g03323937The seatbelt beacon relay controls the operation of the seat belt beacon. The relay acts as an electrical switch. The ECM energizes the relay, which then allows a power source to flow to the seatbelt beacon.Horn Relay
Illustration 5 g03323937The horn relay controls the operation of the horn. The relay acts as an electrical switch. The ECM energizes the relay, which then allows a power source to flow to the horn.Floodlamps Switch
Illustration 6 g03859812When the floodlamp switch is pressed, a signal is sent through SAE J1939 CAN Data Link to the ECM. The ECM is able to determine the operators request for controlling the lights.Heated Glass Switch
Illustration 7 g03859799When the heated glass switch is pressed, a signal is sent through SAE J1939 CAN Data Link to the ECM. The ECM is able to determine the operators request for controlling the heated glass.Heated Mirror Switch
Illustration 8 g03859863When the heated mirror switch is pressed, a signal is sent through SAE J1939 CAN Data Link to the ECM. The ECM is able to determine the operators request for controlling the heated glass.Seatbelt Switch
Illustration 9 g03350093The seatbelt switch is a single pole switch. The switch has a normally connected and a normally open contact. When the switch is not engaged the normally connected contact is connected to the return, and the normally open contact floats to a high voltage state. When the switch is engaged, the normally open contact is connected to the return and the normally connected contact floats to a high voltage state. Based on the voltage state of the two ECM contacts, the ECM determines if the switch is engaged. The switch alerts the ECM of the state of the seatbelt.Heated Glass Relay
Illustration 10 g03323937The heated glass relay controls the operation of the window heaters. The relay acts as an electrical switch. The ECM energizes the relay, which then allows a power source to flow to the heaters.Front Heated Window Relay
Illustration 11 g03323937The heated glass relay controls the operation of the front window heater. The relay acts as an electrical switch. The ECM energizes the relay, which then allows a power source to flow to the heater.Heated Mirror Relay
Illustration 12 g03323937The heated glass relay controls the operation of the mirror heaters. The relay acts as an electrical switch. The ECM energizes the relay, which then allows a power source to flow to the heaters.Fuel Level Sensor
Illustration 13 g06097985The fuel level sensor utilizes a rheostat type sensor that translates vertically along the sensor rod. to provide a variable resistance. As the resistance changes, the voltage applied to the sensor also changes allowing the fuel level to be determined.Backup Alarm Relay
Illustration 14 g03323937The backup alarm relay is controlled by the Chassis ECM and allows power to flow to the backup alarm when the relay is activated.
