WIRING DIAGRAM

PROCEDURE

1.	READ VALUE USING TECHSTREAM (FUEL INPUT)

(a) Connect the Techstream to the DLC3.

(b) Turn the ignition switch to ON.

(d) Enter following menus: Body Electrical / Combination Meter / Data List.

(e) Check the values by referring to the table below.

Combination Meter

Tester Display	Measurement Item/Range	Normal Condition	Diagnostic Note
Fuel Input	Fuel input signal/Min.: 0, Max.: 127.5	The current fuel level displayed	Unit: Liter

Result	Proceed to
Fuel level data can be displayed on the Techstream and DTC B1500 is output.	A
Fuel level data cannot be displayed on the Techstream.	B

REPLACE COMBINATION METER ASSEMBLY

2.	INSPECT COMBINATION METER ASSEMBLY

(a) Disconnect the E2 connector.

(b) Measure the resistance according to the value(s) in the table below.

Standard Resistance:

Tester Connection	Condition	Specified Condition
E2-9 (FR) - E2-23 (FE)	Always	6.5 to 187.2 Ω*1
E2-9 (FR) - E2-23 (FE)	Always	6.5 to 227.3 Ω*2

REPLACE COMBINATION METER ASSEMBLY

3.	CHECK HARNESS AND CONNECTOR (COMBINATION METER ASSEMBLY - FUEL SENDER GAUGE ASSEMBLY)

(a) Disconnect the L12 connector.

(b) Measure the resistance according to the value(s) in the table below.

Standard Resistance:

Tester Connection	Condition	Specified Condition
E2-9 (FR) - L12-2	Always	Below 1 Ω
E2-9 (FR) - Body ground	Always	10 kΩ or higher
E2-23 (FE) - M12-2	Always	Below 1 Ω
E2-23 (FE) - Body ground	Always	10 kΩ or higher
L12-3 - M12-1	Always	Below 1 Ω
M12-1 - Body ground	Always	10 kΩ or higher

REPAIR OR REPLACE HARNESS OR CONNECTOR

4.	INSPECT FUEL SENDER GAUGE ASSEMBLY

(a) Remove the fuel sender gauge assembly (See page (Main),
(Sub)).

(b) Check that the float moves smoothly between E and F.

Standard Resistance (Main):

Tester Connection	Condition	Specified Condition
1 - 2	Float level is F (upper)	6.5 to 8.5 Ω
1 - 2	Float level is between F (upper) and E (lower)	6.5 to 187.2 Ω (Gradually changes)
1 - 2	Float level is E (lower)	183.2 to 187.2 Ω

Standard Resistance (Sub):

Tester Connection	Condition	Specified Condition
1 - 2	Float level is F (upper)	6.5 to 8.5 Ω
1 - 2	Float level is between F (upper) and E (lower)	6.5 to 227.3 Ω (Gradually changes)
1 - 2	Float level is E (lower)	222.3 to 227.3 Ω
