Title: AIR CONDITIONING: POWER TRANSISTOR (for Rear Heater): INSPECTION; 2006 MY Land Cruiser [05/2005 -        ]

INSPECTION

1. INSPECT POWER TRANSISTOR

(a) Connect the positive (+) lead to terminal 1 through a 12 V - 3.4 W test bulb and negative (-) lead to terminal 2.

(b) Check the test bulb comes on when another positive (+) lead is connected to terminal 4 through a 12 V - 3.4 W test bulb. If operation is not as specified, replace the power transistor.

(c) Measure resistance between terminal 3 and 4.

Standard resistance:

2.0 to 2.4 kΩ

If resistance is not as specified, replace the power transistor.
