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

DATA LIST / ACTIVE TEST

1. READ DATA LIST
HINT: 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.
NOTE:
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 Techstream to the DLC3.
(c) Turn the ignition switch ON and the Techstream on.
(d) Enter the following menus: Chassis / Tire Pressure Monitor / Data List.
(e) Following the display on the Techstream, read the "Data List".

Tire Pressure Monitor













HINT:
*1: Displayed only when the ID No. is not registered.
*2: It may take about 2 or 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 C2124/24 C2121.

2. PERFORM ACTIVE TEST
HINT: Performing the Active Test using the Techstream allows the relays, actuators, etc. to operate without removal of parts. Performing the Active Test as the first step of troubleshooting is one way to save time.
It is possible to display the Data List during the Active Test.

(a) Turn the ignition switch OFF.
(b) Connect the Techstream to the DLC3.
(c) Turn the ignition switch ON and the Techstream on.
(d) Enter the following menus: Body Electrical / Combination Meter / Active Test.
(e) According to the display on the Techstream, perform the "Active Test".
