PINPOINT TEST AI : THE DTE (DISTANCE TO EMPTY) DISPLAY IS INCORRECT OR FLUCTUATES

NOTE: The DTE display and the fuel gauge both use the fuel level input from the fuel tank to provide their respective functions. If the fuel gauge doesn't function correctly, both the fuel gauge and the DTE display are affected.

NOTE: The actual DTE can be higher or lower than the DTE displayed in the message center due to changes in driving conditions. It is important to understand how the DTE is calculated and the factors that impact the DTE display when determining how to address any DTE concerns.

NOTE: Even if the fuel economy is relatively constant, the DTE can vary in the short term by up to 50 miles, but is usually within 10 miles.

Normal Operation and Fault Conditions

See DTE/Average Fuel Economy (AFE). REFER to: Message Center - System Operation and Component Description (413-01 Instrumentation, Message Center and Warning Chimes, Description and Operation).

The DTE is calculated in the PCM using the PCM internal Running Average Fuel Economy (RAFE), which is the fuel economy over a much longer distance than the Instantaneous Fuel Economy (IFE). The PCM Running Average Fuel Economy (RAFE) is not displayed in the IPC. The IPC shows a static value for Running Average Fuel Economy (RAFE) in Engineering Test mode. The fuel level input from the fuel sender(s), fuel consumption and odometer are used to determine how many miles the vehicle can be driven based on the remaining fuel in the tank. The speedometer signal is required to determine whether a refueling event is detected accurately.

The PCM defaults to a preset baseline L/100km (mpg) Running Average Fuel Economy (RAFE) when the keep alive memory is reset or the PCM is flashed and changes afterward based on driving habits and conditions.

Since the DTE is calculated and averaged over a longer period of time, varying driving conditions can have a significant impact on the current or short term DTE as opposed to the displayed DTE. This difference often leads to customer complaints of incorrect or invalid DTE.

The following list provides some (not all) of the driving conditions that may lead to an incorrect or fluctuating DTE concern:

  • Changing between towing/not towing
  • Changing driving between city and highway
  • Allowing the vehicle to idle for long periods of time
  • Using the remote start feature (if equipped) frequently or allowing the vehicle to warm up, particularly when parked on a grade
  • Parking or driving on grades
  • Inconsistent use of gasoline or E85 fuels
  • Over-fueling or not filling the tank completely (trickle filling at above full, partial refueling with less than 10% of fuel tank capacity)

The PCM uses the following network inputs to control the DTE.

  • Fuel alcohol percent
  • Fuel flow volume
  • Odometer count
  • Transport mode
  • Fuel level input from the IPC

The DTE features the following:

DTE decreases while driving, but can increase if fuel economy improves. After a period of high consumption and entering a state of low consumption, it is possible that DTE will not change for a period of time.

DTE calculation considers the amount of fuel above an empty indication. There is a certain amount of reserve fuel below the empty indication ( DTE equals 0) which allows for a minimal distance of additional driving. This fuel volume is not a specified amount and should not be relied upon.

Possible Sources

  • Fuel gauge concern
  • Changing between city and highway driving
  • Extended idle times
  • Using the remote start feature (if equipped) frequently or allowing the vehicle to warm up, particularly when parked on a grade
  • Parking or driving on grades
  • Inconsistent use of gasoline or E85 fuels
  • Over-fueling or not filling the tank completely (trickle filling at above full, partial refueling with less than 10% of fuel tank capacity)
  • PCM concern
  • IPC configuration

Visual Inspection and Pre-checks

  • If any of the previous conditions occur, the vehicle must be driven over time to allow the DTE calculations to adjust.
AI1 REVIEW AND INVESTIGATE THE FOLLOWING DRIVING CONDITIONS WITH THE CUSTOMER
  • Determine whether the driver changes the following driving conditions:
    • changing between towing/not towing, city/highway driving
    • use of extended idle times
    • use of remote start frequently (if equipped)
    • parking/driving on grades
    • use of E85 fuel exclusively or switching to non-Ethanol fuel
    • over filling the fuel tank or not filling the tank completely (partial refueling)

Does the driver change driving conditions?
Yes Advise the customer how changing driving conditions can affect the current short-term DTE as opposed to the displayed long-term DTE.
