INSPECTION PROCEDURE

PROCEDURE

1. PERFORM ACTIVE TEST USING TECHSTREAM (FUEL METER OPERATION)
(a) Connect the Techstream to the DLC3.
(b) Turn the power switch on (IG).
(c) Turn the tester ON.
(d) Enter following menus: Body Electrical / Combination Meter / Active Test.
(e) Check the operation by referring to the table below.

Combination Meter:

OK:
Needle indication is normal.
NG -- REPLACE COMBINATION METER
OK -- Continue to next step.
2. READ VALUE USING TECHSTREAM (FUEL INPUT)
(a) Connect the Techstream to the DLC3.
(b) Turn the power switch on (IG).
(c) Turn the tester ON.
(d) Enter following menus: Body Electrical / Combination Meter / Data List.
(e) Check the values by referring to the table below.

Combination Meter:

OK:
Fuel value signal displayed on the tester is almost the same as needle indication.
NG -- REPLACE COMBINATION METER
OK -- Continue to next step.
3. INSPECT FUEL SENDER GAUGE (for Main)

(a) Disconnect the V11 gauge connector.
(b) Measure the voltage of the wire harness side connector.
Standard voltage:

(d) Check that the float position is between E and F.
(e) Measure the resistance between the terminals 2 and 3 of connector.
Standard resistance:

NG -- REPLACE FUEL SENDER GAUGE
OK -- Continue to next step.
4. INSPECT FUEL SENDER GAUGE (for Sub)

(a) Disconnect the U9 gauge connector.
(b) Measure the voltage of the wire harness side connector.
Standard voltage:

(d) Check that the float position is between E and F.
(e) Measure the resistance between the terminals 2 and 3 of connector of the connector.
Standard resistance:

NG -- REPLACE FUEL SENDER GAUGE
OK -- Continue to next step.
5. CHECK WIRE HARNESS (COMBINATION METER - FUEL SENDER GAUGE)

(a) Disconnect the V11 fuel sender gauge connector.
(b) Disconnect the K31 meter connector.
(c) Measure the resistance of the wire harness side connectors.
Standard resistance:

NG -- REPAIR OR REPLACE HARNESS OR CONNECTOR
OK -- Continue to next step.
6. CHECK WIRE HARNESS (FUEL SENDER GAUGE - FUEL SENDER GAUGE)

(a) Disconnect the U9 and V11 fuel sender gauge connectors.
(b) Measure the resistance of the wire harness side connectors.
Standard resistance:

NG -- REPAIR OR REPLACE HARNESS OR CONNECTOR
OK -- Continue to next step.
7. CHECK WIRE HARNESS (COMBINATION METER - FUEL SENDER GAUGE)

(a) Disconnect the V11 gauge connector.
(b) Disconnect the K31 meter connector.
(c) Measure the resistance of the wire harness side connectors.
Standard resistance:

NG -- REPAIR OR REPLACE HARNESS OR CONNECTOR
OK -- REPLACE COMBINATION METER
