DATA LIST
Tech Tips
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.
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 intelligent tester to the DLC3.
Turn the power switch on (IG).
Turn the intelligent tester on.
Enter the following menus: Body / Pre-Crash / Data List.
Enter the following menus: Body / Pre-Crash 2 / Data List.
Read the Data List according to the display on the intelligent tester.
Tech Tips
As the driving support ECU and seat belt control ECU both have Data List for the pre-crash system, be sure to check the Pre-Crash and Pre-Crash 2 Data Lists.

ACTIVE TEST
Tech Tips
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 power switch on (IG).
Turn the intelligent tester on.
Enter the following menus: Body / Pre-Crash / Active Test.
Perform Active Test according to the display on the intelligent tester.
Tech Tips
The power switch must be turned on (IG) to proceed with the Active Test using the intelligent tester.
| Tester Display | Test Part | Control Range | Diagnostic Note |
|---|---|---|---|
| Driver Seat Belt Motor | Driver seat belt motor | ON: Seat belt motor operates OFF: Seat belt motor does not operate |
Seat belt (driver side) is fastened |
| Passenger Seat Belt Motor | Passenger seat belt motor | ON: Seat belt motor operates OFF: Seat belt motor does not operate |
Seat belt (front passenger side) is fastened |
| Driver and Passenger Seat Belt Motor | Driver and passenger seat belt motors | ON: Seat belt motors operate OFF: Seat belt motors do not operate |
Seat belts (driver and front passenger sides) are fastened |
Note
The seat belt motor will only operate when the tongue plate is inserted into the buckle (seat belt fastened).
To prevent overheating the belt motor, this test cannot be activated continuously. Operate the belt motor at an interval of 30 seconds or more.
