The pointer of the fuel gauge is moved by the magnetic fields of two coils. The coils are at right angles to each other. Voltage is available from the GAUGES fuse through CKT 39 (PNK) when the ignition switch is in RUN or START position. Voltage is applied to the E-coil and the circuit divides at the opposite end of the coil. One path continues to ground G 108 through the F-coil on CKT 451 (BLK/WHT). The other path, through CKT 30 (PPL), travels to the variable resistor of the fuel level sensor in the fuel pump module. When the level in the fuel tank is low, the resistance to ground in the fuel level sensor is low. More of the current then flows directly through the E-coil. This condition pulls the pointer toward E on the fuel gauge. When the fuel tank is full, the resistance to ground in the fuel level sensor is high. More current then flows through both the F-coil. The pointer moves toward F on the fuel gauge.

The ABS indicator warns the driver that there is a problem with the anti-lock brake system. Voltage is supplied to the indicator from the GAUGES fuse when the ignition switch in the RUN or START position through CKT 39 (PNK). The electronic brake control module (EBCM) provides ground to the indicator through CKT 867 (LT GRN) at the ABS indicator lamp control.

The indicator will illuminate under a number of conditions associated with either the hydraulic brake system or park brake system.
