Scan Tool Testing and Procedures

TIRE AND WHEEL: TIRE PRESSURE WARNING SYSTEM: DATA LIST / ACTIVE TEST

1. READ 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.

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 Techstream to the DLC3.

(c) Turn the ignition switch on (IG) and turn the tester on.

(d) Enter the following menus: Chassis / Tire Pressure Monitor / Data List.

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









HINT
*1: Displayed only when the ID No. is not registered.

*2: It may take about 2 to 3 minutes until the values are displayed. If the values are not displayed after a few minutes, perform troubleshooting according to the inspection procedure for DTCs C2121/21 to C2125/25 C2121

2. ACTIVE TEST

HINT
Using Techstream to perform ACTIVE TEST allows the meters, indicators 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 TEST early in troubleshooting is one way to save diagnostic time. It is possible to display the DATA LIST on Techstream during ACTIVE TEST.

(a) Turn the ignition switch off.

(b) Connect Techstream to the DLC3.

(c) Turn the ignition switch on (IG) and turn the tester ON.

(d) Enter the following menus: Body / Combination Meter / Active Test.

(e) According to the display on the tester, perform the "ACTIVE TEST".
