READ DATA LIST
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.
Connect the intelligent tester to the DLC3.
Turn the ignition switch on (IG) and turn the intelligent tester on.
Read the Data List by following the prompts on the tester.

PERFORM ACTIVE TEST
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 on (IG) and turn the intelligent tester on.
Perform the Active Test by following the prompts on the tester.
| Tester Display | Test Part | Control Range | Diagnostic Note |
|---|---|---|---|
| Magnetic Clutch Relay | Magnetic clutch relay | OFF, ON | - |
| Defogger Relay (Rear) | Defogger relay (Rear) | OFF, ON | - |
