DATA LIST / ACTIVE TEST

1. DATA LIST

Using the 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.

NOTICE:

In the table below, the values listed under "Normal Condition" are reference values. Do not depend solely on these reference values when deciding whether a part is faulty or not.

(a) Connect the Techstream to the DLC3.

(b) Turn the ignition switch to ON.

(d) Enter the following menus: Body / Air Conditioner / Data List.

(e) Check the value(s) by referring to the table below.

2. ACTIVE TEST

Using the 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 the Techstream to the DLC3.

(b) Turn the ignition switch to ON.

(d) Enter the following menus: Body / Air Conditioner / Active Test.

(e) Check the operation by referring to the table below.

Air Conditioner

Tester Display	Test Part	Control Range	Diagnostic Note
Blower Motor	Blower motor	Min.: 0, Max.: 31	-
Magnetic Clutch Relay	A/C compressor	OFF, ON	-
Defogger Relay (Rear)	Defogger relay (Rear)	OFF, ON	-
Air Mix Servo Targ Pulse (D)	Air mix servo motor pulse (D side)	Min.: 0, Max.: 255	-
Air Mix Servo Targ Pulse (P)	Air mix servo motor pulse (P side)	Min.: 0, Max.: 255	-
Air Outlet Servo Pulse (D)	Air outlet servo motor pulse	Min.: 0, Max.: 255	-
Air Inlet Damper Targ Pulse	Air inlet damper target pulse	Min.: 0, Max.: 255	-
