DATA LIST / ACTIVE TEST
HINT:
By accessing the Data List displayed by the Techstream, you can check values of switches and sensors without removing any parts. Reading the Data List as the first step of troubleshooting is one method to shorten diagnostic time.
1. DATA LIST FOR OCCUPANT DETECTION ECU
(a) Connect the Techstream to the DLC3.
(b) Turn the ignition switch to the on position.
(c) Following the display on the Techstream screen, read the Data List.
