Fuel Gauge: Testing and Inspection

Fuel Gauge, Checking

If the fuel gauge displays the contents of the fuel tanks as being too high or too low, the fuel gauge needle position can be corrected (adapted).

First perform the following procedures:

- Perform Output Diagnostic Test Mode (DTM) for instrument cluster. Refer to "Scan Tool Testing/Output Diagnostic Test Mode (DTM) (Function 03)" Testing and Inspection

If Output Diagnostic Test Mode (DTM) does not recognize a malfunction, check function of sender for fuel gauge -G-:

- Check resistance value of sender for fuel gauge using Read Measuring Value Block (function 08), display group 002. Refer to "Scan Tool Testing/Measuring Value Blocks (Function 08)/Reading" Testing and Inspection

If Read Measuring Value Block does not indicate a short or open circuit in the wiring or the fuel gauge sender, continue with adaptation.
