AIR CONDITIONING: AIR CONDITIONING SYSTEM (for Automatic Air Conditioning System): DATA LIST / ACTIVE TEST

DATA LIST / ACTIVE TEST

1. DATA LIST
HINT: Using Techstream 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.

(a) Connect Techstream to the DLC3.
(b) Turn the ignition switch to the ON position.
(c) From the display on the tester, read the "Data List".

HINT: *1: It differs depending on the user setting.

2. ACTIVE TEST
HINT: Using Techstream 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.

(a) Connect Techstream to the DLC3.
(b) Turn the ignition switch to the ON position.
(c) From the display on the tester, read the "Active Test".
