Land Cruiser URJ200 URJ202 GRJ200 VDJ200 - HEATING / AIR CONDITIONING
AIR CONDITIONING SYSTEM (for Manual Air Conditioning System) - DATA LIST / ACTIVE TEST
- HINT:
- Using the intelligent tester to read the Data List allows the values or states of switches, sensors, actuators and other items to be read without removing any parts. This non-intrusive inspection can be very useful because intermittent conditions or signals may be discovered before parts or wiring is disturbed. Reading the Data List information early in troubleshooting is one way to save diagnostic time.
- NOTICE:
- In the table below, the values listed under "Normal Condition" are reference values. Do not depend solely on these reference values when deciding whether a part is faulty or not.

ACTIVE TEST |
- HINT:
- Using the intelligent tester to perform Active Tests allows relays, VSVs, actuators and other items to be operated without removing any parts. This non-intrusive functional inspection can be very useful because intermittent operation may be discovered before parts or wiring is disturbed. Performing Active Tests early in troubleshooting is one way to save diagnostic time. Data List information can be displayed while performing Active Tests.
Connect the intelligent tester to the DLC3.
Turn the ignition switch to ON.
Turn the intelligent tester on.
Enter the following menus: Body / Air Conditioner / Active Test.
According to the display on the intelligent tester, perform the Active Test.
Tester Display | Test Part | Control Range | Diagnostic Note |
Blower Motor | Blower with fan motor sub-assembly | Min.: 0, Max.: 31 | - |
Magnetic Clutch Relay | Magnet clutch relay | OFF or ON | - |
