Entry And Start System -- 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 as 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.
  1. Connect the intelligent tester to the DLC3.

  2. Turn the engine switch on (IG).

  3. Read the DATA LIST.

PERFORM ACTIVE TEST
HINT:
Performing the intelligent tester's ACTIVE TEST allows the relay, VSV, actuator and other items to be operated without removing any parts. Performing the ACTIVE TEST early in troubleshooting is one way to save time. The DATA LIST can be displayed during the ACTIVE TEST.
  1. Connect the intelligent tester to the DLC3.

  2. Turn the engine switch on (IG).

  3. Perform the ACTIVE TEST according to the display on the tester.
