Title: METER / GAUGE / DISPLAY: METER / GAUGE SYSTEM (for 12.3 Inch Display): Fuel Receiver Gauge Malfunction; 2023 MY Corolla Corolla Hatchback Corolla HV GR Corolla [09/2022 - 11/2022]

Fuel Receiver Gauge Malfunction

DESCRIPTION

FUEL RECEIVER GAUGE DESCRIPTION

  • The combination meter assembly receives the fuel level signal via direct line from the fuel sender gauge assembly and No. 2 fuel sender gauge assembly and the fuel consumption signal from the ECM via CAN communication, then calculates the fuel level in the fuel tank and displays the calculated value on the fuel receiver gauge.

FUEL RECEIVER GAUGE CONTROL

(a) During normal driving:

  • During driving, the value of the fuel receiver gauge is updated based on the reduction in the fuel level. The reduction is calculated by deducting the value calculated based on the fuel consumption signal sent by the ECM from the value calculated based on the signal sent by the fuel sender gauge assembly and No. 2 fuel sender gauge assembly.

(b) During refueling:

  • As the fuel level in the fuel tank increases during refilling, the output value of the fuel sender gauge assembly and No. 2 fuel sender gauge assembly changes. When the combination meter assembly detects a change in the output value of the fuel sender gauge assembly and No. 2 fuel sender gauge assembly of a certain value or more, it determines that fuel is being added and calculates the added amount. This control is called refueling judgment and the fuel receiver gauge display is updated in accordance with the fuel level calculated based on the refueling judgment.

CAUTION / NOTICE / HINT

NOTICE:

  • When replacing the combination meter assembly, always replace it with a new one. If a combination meter assembly which was installed to another vehicle is used, the information stored in it will not match the information from the vehicle and a DTC may be stored.
  • When replacing the combination meter assembly, update the ECU security key.

END (TEMPORARY ERROR DUE TO FUEL RECEIVER GAUGE CHARACTERISTICS)

HINT:

It is suspected that the indicated value of the fuel receiver gauge did not automatically update due to the following reasons:

  • The amount of added fuel was less than the refueling judgement amount.
  • Refueling was performed in a range for which detection is not possible (indicated value of fuel receiver gauge was near E, F)

B

5.

CHECK FUEL RECEIVER GAUGE (OPERATION BY ADDING FUEL)

NOTICE:

As it is necessary to add more than a certain amount of fuel to the fuel tank, if the fuel level is near full, perform the following procedure then proceed to step (a). If the fuel tank is not near full, proceed to step (a) without performing the following procedure.

  1. Turn the ignition switch off.
  2. Remove 15 liters (15.9 US qts, 13.2 Imp. qts) or more of fuel from the fuel tank.
  3. Turn the ignition switch to ON.
  4. Wait 6 minutes or more.
  5. Confirm that the fuel receiver gauge indicates a value in accordance with the removed amount of fuel.

(a) Record the fuel receiver gauge reading.
