Land Cruiser URJ200 URJ202 GRJ200 VDJ200 - SUSPENSION CONTROL
ACTIVE HEIGHT CONTROL SUSPENSION - DATA LIST / ACTIVE TEST
| READ DATA LIST |
- 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.
Turn the engine switch off.
Connect the intelligent tester to the DLC3.
Turn the engine switch on (IG) and the tester on.
Enter the following menus: Chassis / AHC / Data List.
According to the display on the tester, read the Data List.

| PERFORM 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.
