4. System Sensors Check
On the Function Check/Setting screen, click Touch Switch to display the following screen.
GPS related check: Status of the GPS signal reception can be checked. When there is faulty in reception status, position detection or date indication, re-check the reception status at a location with a fine view and no obstacles around that will interrupt the signal reception. When normal condition is still not obtained, the GPS antenna may be faulty.
• GPS/Reception number: Normal when it is indicated in blue.
• GPS/Status: Normal when OK is indicated.
• GPS/Measurement ratio 3D:
• GPS/Measurement ratio 2D:

SPD check: Status of the vehicle speed sensor signal can be checked.
(1) Before starting inspections, check the safety around the vehicle. (Lift up the vehicle as necessary.)
(2) When VDC CM detected DTC, clear the DTC.
(3) Drive the vehicle at 9 km/h (6 MPH) or more.
(4) Check that SPD indicates vehicle speed that is almost equivalent to the figure displayed on the combination meter.
(5) Vehicle speed is not displayed. Or, when the vehicle speed is not correct, check if the DTC related to the vehicle sensor is stored for the VDC system, and perform inspection according to the procedure. If no fault is found with the vehicle speed sensor, and the vehicle speed is displayed on the combination meter, the unit itself may be faulty.
