1. | CHECK CONDITION |
| (a) Check with the customer if the vehicle has been turned by a turntable. OK: Vehicle has not been turned by a turntable. HINT: If the vehicle is turned on a turntable with the engine switch on (IG), the system may store the angular velocity. As a result, the vehicle position cursor may deviate. In this case, the vehicle position cursor will return to normal by turning the engine switch off and back to on (IG) again with the vehicle completely stopped. |

DATA LIST / ACTIVE TEST
DATA LIST
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.
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.
(a) Connect the Techstream to the DLC3.
(b) Turn the engine switch on (IG).
(c) Turn the Techstream on.
(d) Enter the following menus: Body Electrical / Navigation System / Data List.
(e) Read the Data List according to the display on the Techstream.
