Condition for fault identification

Test condition:

The diagnostic fault code is logged when the fuel level calculated by the DME deviates too starkly from the instrument cluster's fuel level.

Potential problem source(s):

• Defective fuel-level sensor
• Frequent refueling with quantities of less than 5 liters (as with rental vehicles)

Terminal condition: none

Voltage condition:

• None

Temperature condition:

• None

Time condition:

• 21 sec. after Terminal 15 on

Other conditions:

• Engine on
• No fault related to tank fuel-level sensor is currently present
• At least 20 liters of fuel must be consumed without refueling (multiple cycles possible)
