Fuel Level Specifications

The information in this table is intended for use with the J 33431-C Signal Generator and Instrument Panel Tester. See Special Tools and Equipment . The fuel level sensor values represent the test values to be used on the Signal Generator to drive the fuel gage display to the indicated positions. Vehicles that require more than one fuel level sensor calculate gage position from many possible resistance combinations of fuel levels between the two tanks. Therefore, the values in the table may not correlate directly to readings taken from the vehicle primary or secondary sending units.

The values in the table are approximate values based on information obtained from properly operating vehicles. Actual results may vary slightly.

The fuel level sender changes resistance based on fuel level. The engine control module (ECM) monitors the signal circuit of the fuel level sender in order to determine fuel level. When the fuel tank is full, the sender resistance is high and the ECM senses a high signal voltage. When the fuel tank is empty, the sender resistance is low and the ECM senses a low signal voltage. The ECM uses the signal circuit of the fuel level sender in order to calculate the total remaining fuel percent in the tank. The ECM sends the fuel level percent via the class 2 serial data circuit to the instrument cluster in order to control the fuel gage. The fuel level information is also used for misfire and EVAP diagnostics.

This diagnostic tests for a stuck primary fuel level sensor signal. The ECM sets this DTC if the primary fuel level sensor signal appears to be stuck based on a lack of signal variation expected during normal operation.

1. Use the Freeze Frame/Failure Records data in order to locate an intermittent condition. If you cannot duplicate the DTC, the information included in the Freeze Frame/Failure Records data may help in determining the number of miles since the DTC set. The Fail Counter and Pass Counter can also help in determining the number of ignition cycles that the diagnostic test reported a pass and/or fail. Operate the vehicle within the same freeze frame conditions, including those for RPM, for engine load, for vehicle speed, for temperature, and for others. This will isolate at what point the DTC failed.
2. Refer to «Testing for Intermittent Conditions and Poor Connections»(/buick/rendezvous/i-2001-2007/remont/body-electrical/#wiring-systems-diagnostic-information-and-procedures__testing-for-intermittent-conditions-and-poor) in Wiring Systems.

Compass Calibration

To calibrate the compass depress and hold the Set button for 3 seconds while the DIC is in the Compass/Temperature mode. The DIC then displays ZONE XX PRESS AND HOLD SET TO CHANGE. Press the set button to change the variation zone. Then press the Mode button. The DIC displays PRESS SET TO CALIBRATE COMPASS. Press the Set button. Then the DIC displays DRIVE VEHICLE IN CIRCLES. Drive the vehicle in 3 complete circles at least 5 mph in a magnetically clean area. While driving the vehicle in circles the DIC will display CALIBRATING. When the calibration is completed the DIC displays the normal mode of compass/temperature.

Scheme 14

Compass variation is the difference between magnetic north and geographic north. In some areas of the country the difference is great enough to cause the compass to give a false reading. If this occurs, the compass variance must be set. View the Variance Zone Display to determine the correct zone. The zones are numbered 1-15. Depress and hold both the MODE and the SET buttons simultaneously while the DIC is in the Compass/Temperature mode for 5 seconds. After 5 seconds, the DIC will display the current variation setting. Release the buttons and adjust to the correct variation number using the MODE button. Consult the map for variation zone numbers. When the desired variation is reached press the Set button to accept.

You cannot reset the Compass/Temperature mode. This mode is retained during ignition OFF.
