METER: METER / GAUGE SYSTEM (for Hatchback): Fuel Gauge Malfunction

Fuel Gauge Malfunction

DESCRIPTION

The combination meter assembly controls the fuel receiver gauge in accordance with the resistance of the fuel sender gauge that varies depending on the fuel remaining amount in the fuel tank.

INSPECTION PROCEDURE

PROCEDURE

1. PERFORM ACTIVE TEST USING TECHSTREAM (FUEL GAUGE)




(a) Connect the Techstream to the DLC3.
(b) Turn the ignition switch ON and turn the tester ON.
(c) Enter the following menus: Body Electrical / Combination Meter / Active Test.
Body Electrical / Combination Meter / Active Test::






OK:
Fuel receiver gauge segments are illuminated in accordance with the tester instructions.
NG -- REPAIR OR REPLACE HARNESS OR CONNECTOR
OK -- Continue to next step.
2. READ VALUE USING TECHSTREAM (FUEL GAUGE)
(a) Connect the Techstream to the DLC3.
(b) Turn the ignition switch ON and turn the tester ON
(c) Select the item below from the Data List, and read the value displayed on the Techstream.
Body Electrical / Combination Meter / Data List::






OK:
Fuel input signal displayed on the tester is approximately the same as indication.
NG -- REPAIR OR REPLACE HARNESS OR CONNECTOR
OK -- Continue to next step.
3. CHECK COMBINATION METER ASSEMBLY




(a) Disconnect the J5 fuel sender gauge assembly connector.
(b) Remove the combination meter assembly with its connectors connected.
(c) Measure the voltage.
Standard voltage:





(d) Reconnect the fuel sender gauge assembly connector.
(e) Reinstall the combination meter assembly.
NG -- REPAIR OR REPLACE HARNESS OR CONNECTOR
OK -- Continue to next step.
4. INSPECT FUEL SENDER GAUGE ASSEMBLY




(a) Remove the fuel sender gauge assembly.
(b) Check that the float position is between E and F.
(c) Measure the resistance between terminals 2 and 1 of the fuel sender gauge connector.
Standard resistance:





(d) Reinstall the fuel sender gauge assembly.
NG -- REPLACE FUEL SENDER GAUGE ASSEMBLY
OK -- Continue to next step.
5. CHECK HARNESS AND CONNECTOR (COMBINATION METER ASSEMBLY - FUEL SENDER GAUGE ASSEMBLY)




(a) Disconnect the D1 combination meter assembly connector.
(b) Disconnect the J5 fuel sender gauge assembly connector.
(c) Measure the resistance.
Standard resistance:





(d) Reconnect the combination meter assembly and fuel sender gauge assembly connectors.
NG -- REPAIR OR REPLACE HARNESS OR CONNECTOR
OK -- REPLACE COMBINATION METER ASSEMBLY
