DATA LIST
Tech Tips
Using the GTS 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.
Note
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.
Connect the GTS to the DLC3.
Turn the ignition switch to ON.
Turn the GTS on.
Enter the following menus:
Body / Air Conditioner / Data List.
Body / Combination Meter / Data List.
Powertrain / Engine and ECT / Data List.
According to the display on the GTS, read the Data List.
| Tester Display | Measurement Item/Range | Normal Condition | Diagnostic Note |

ACTIVE TEST
Tech Tips
Using the GTS 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 GTS to the DLC3.
Turn the ignition switch to ON.
Turn the GTS on.
Enter the following menus: Body / Air Conditioner / Active Test.
According to the display on the GTS, perform the Active Test.
| Tester Display | Test Part | Control Range | Diagnostic Note |
|---|---|---|---|
| Magnetic Clutch Relay | Magnet clutch relay operation | ON or OFF | - |
