Pre-Crash Safety System -- Data List / Active Test



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 are 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. By following the display on the tester, select the "Data List".
