VARIABLE GEAR RATIO STEERING SYSTEM > DATA LIST / ACTIVE TEST
for Preparation Click here
HINT:
Using the intelligent tester 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.
READ DATA LIST
a. Connect the intelligent tester to the DLC3.
b. Turn the engine switch on (IG).
c. Turn the tester on.
d. Enter the following menus: Chassis / VGRS / Data List.
e. According to the display on the tester, read the Data List.
