Fuel Distance/Mileage Module: Testing and Inspection

Fuel consumption signal, checking

This signal is used for the fuel consumption display in the instrument cluster.

If the instrument cluster displays a incorrect fuel consumption readout.
- Perform adaptation of fuel consumption display to actual consumption.

If no fuel consumption readout is displayed in the instrument cluster:
- Connect VAG 1598/31 test box to wiring harness for engine control module. DO NOT connect to engine control module itself, Refer to "Scan Tool Testing/Scan Tool Connecting and Initial Checks/Connecting VAG 1598/31 Test Box" Testing and Inspection

The following wiring connection is to be checked for short circuit to B+, short circuit to Ground (GND) and an open circuit.

VAG 1598/31 Instrument cluster,
test box socket terminal
81

Wiring resistance: max. 1.5 Ohm

- If necessary eliminate open circuit or short circuit.
- Display readiness code, Refer to "Monitors, Trips and/or Drive Cycle (Readiness Codes)/Displaying Readiness Code" Testing and Inspection . Readiness code must be generated if DTC memory was erased, Refer to "Monitors, Trips and/or Drive Cycle (Readiness Codes)/Generating Readiness Code" Testing and Inspection
