PROCEDURE

1.CHECK HARNESS AND CONNECTOR (4WD ECU ASSEMBLY - FRONT 4WD LINEAR SOLENOID (TRANSFER ASSEMBLY))

Turn the engine switch off.

Disconnect the N3 4WD ECU assembly connector.

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

Standard Resistance:

Tester Connection	Condition	Specified Condition
N3-5 (SLF+) - N3-6 (SLF-)	20°C (68°F)	0.73 to 0.83 Ω
N3-5(SLF+) - Body ground	Always	10 kΩ or higher

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

Standard Voltage:

Tester Connection	Condition	Specified Condition
N3-6(SLF-) - Body ground	Always	Below 1 V

Result:

Proceed to
OK
NG

Standard Resistance:

Tester Connection	Condition	Specified Condition
N3-5(SLF+) - C60-2(SLF+)	Always	Below 1 Ω
N3-6(SLF-) - C60-1(SLF-)	Always	Below 1 Ω
N3-5(SLF+) or C60-2(SLF+) - Body ground	Always	10 kΩ or higher
N3-6(SLF-) or C60-1(SLF-) - Body ground	Always	10 kΩ or higher
N3-5(SLF+) or C60-2(SLF+) - N3-6(SLF-) or C60-1(SLF-)	Always	10 kΩ or higher
N3-5(SLF+) - N3-16(SLFS)	Always	10 kΩ or higher
N3-6(SLF-) - N3-16(SLFS)	Always	10 kΩ or higher

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

Standard Voltage:

Tester Connection	Condition	Specified Condition
N3-6(SLF-) or C60-1(SLF-) - Body ground	Always	Below 1 V

Result:
