Land Cruiser URJ200 URJ202 GRJ200 VDJ200 - HEATING / AIR CONDITIONING
AIR CONDITIONING SYSTEM (for Automatic 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.
