DATA LIST (for Type A)
Using the GTS 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.

With the vehicle stopped or driving very slowly, if the steering wheel is turned repeatedly or turned to a lock position and the vehicle is driven for an extended period of time, the amount of power assist is decreased to prevent overheating of the motor and ECU. If this occurs, do not turn the steering wheel for approximately 10 minutes with engine running to improve power assist.
If the battery is not sufficiently charged or the voltage decreases temporarily, the amount of power assist is reduced and the EPS warning light comes on. In such cases, the amount of power assist returns to normal when the battery voltage recovers.

DATE LIST (for Type B)
Using the GTS 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.
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.
Turn the ignition switch off.
Connect the GTS to the DLC3.
Turn the ignition switch to ON.
Turn the GTS on.

With the vehicle stopped or driving very slowly, if the steering wheel is turned repeatedly or turned to a lock position and the vehicle is driven for an extended period of time, the amount of power assist is decreased to prevent overheating of the motor and ECU. If this occurs, do not turn the steering wheel for approximately 10 minutes with engine running to improve power assist.
If the battery is not sufficiently charged or the voltage decreases temporarily, the amount of power assist is reduced and the EPS warning light comes on. In such cases, the amount of power assist returns to normal when the battery voltage recovers.
