Scan Tool Testing and Procedures

DATA LIST / ACTIVE TEST
1. READ DATA LIST

HINT: Using the intelligent tester or 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) Turn the ignition switch OFF.
(b) Connect the intelligent tester or Techstream to the DLC3.
(c) Turn the ignition switch ON.
(d) Turn ON the tester.
(e) Enter the following menu items:
(1) Intelligent tester - Select: DIAGNOSIS / OBD/MOBD / CHASSIS / TIRE PRESSURE / DATA LIST /
(2) Techstream - Select: Chassis / Tire Pressure Monitor / Data List /
(f) Check the values by referring to the table below.
(1) Intelligent tester

TIRE PRESSURE (Part 1):

TIRE PRESSURE (Part 2):

(2) Techstream

Tire Pressure Monitor (Part 1):

Tire Pressure Monitor (Part 2):

HINT:
*1: Displayed only when the transmitter ID is not registered.
*2: It may take up to about 5 to 6 minutes to update the tire pressure data. If the values are not displayed after about 5 to 6 minutes, perform troubleshooting according to the inspection procedure for DTCs C2121/21 to C2124/24. C2121

2. PERFORM ACTIVE TEST

HINT: Using the intelligent tester or 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) Turn the ignition switch OFF.
(b) Connect the intelligent tester or Techstream to the DLC3.
(c) Turn the ignition switch ON.
(d) Turn ON the tester.
(e) Enter the following menus:
(1) Intelligent tester - Select: DIAGNOSIS / OBD/MOBD / BODY / METER / ACTIVE TEST /
(2) Techstream - Select: Body / Combination Meter/Active Test /
(f) According to the display on the tester, perform the "ACTIVE TEST".
