2. ACTIVE TEST
HINT:
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.
(a) Connect the intelligent tester to the DLC3.

(b) As each damper, motor and relay automatically
operate actuator check at 1-second intervals from
step No. 1 to No. 10 continuously, check the
temperature and air flow visually and by hand.
If the slower display is desired, press the DEF
switch and change it to step operation. Each time
the DEF switch is pressed, the display changes by 1
step.
HINT:
• Codes are displayed from smaller to larger
numbers in order.
• To cancel the check mode, press the OFF switch.
