PROCEDURE

1.INSPECT No. 1 4 WHEEL DRIVE POSITION SWITCH

Turn the engine switch off.

Remove the No. 1 4 wheel drive position switch.

*a	Dry Batteries
*b	Component without harness connected (No. 1 4 wheel drive position switch)
*c	Piece of metal

Connect terminal 1 (TVCF) to the batteries positive (+) terminal, and terminal 3 (TEF) to the batteries negative (-) terminal.

Move a piece of metal close to the edge of the No. 1 4 wheel drive position switch, and then move it away and check that the resistance changes.

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

Standard Resistance:

Tester Connection	Condition	Specified Condition
2 (TNF) - 3 (TEF)	Low (Move piece of metal away)	150 to 620 Ω
2 (TNF) - 3 (TEF)	High (Move piece of metal closer)	1.1 to 6.2 kΩ

Result:

Proceed to
OK
NG

2.CHECK HARNESS AND CONNECTOR (4WD ECU ASSEMBLY - No. 1 4 WHEEL DRIVE POSITION SWITCH)

2.CHECK HARNESS AND CONNECTOR (4WD ECU ASSEMBLY - No. 1 4 WHEEL DRIVE POSITION SWITCH)

Turn the engine switch off.

Disconnect the N3 4WD ECU assembly connector.

Disconnect the C59 No. 1 4 wheel drive position switch connector.

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

Standard Resistance:

Tester Connection	Condition	Specified Condition
N3-3 (TNF) - C59-2 (TNF)	Always	Below 1 Ω
N3-11 (TVCF) - C59-1 (TVCF)	Always	Below 1 Ω
N3-18 (TEF) - C59-3 (TEF)	Always	Below 1 Ω
N3-3 (TNF) or C59-2 (TNF) - Body ground and other terminals	Always	10 kΩ or higher
N3-11 (TVCF) or C59-1 (TVCF) - Body ground and other terminals	Always	10 kΩ or higher
N3-18 (TEF) or C59-3 (TEF) - Body ground and other terminals	Always	10 kΩ or higher

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

Standard Voltage:

Tester Connection	Condition	Specified Condition
N3-18 (TEF) or C59-3 (TEF) - Body ground	Always	Below 1 V

Result:
