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:

GPS/Date: Normal when current time is indicated. When current date/time is not indicated, click the Date Setting button to set the current date on the displayed date setting screen.

GPS/Position: Normal when longitude and latitude of the current position are indicated.

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.

Gyro sensor related check: Status of the Gyro sensor signal can be checked. If fault is found with the Gyro sensor related indications, the main unit could be faulty.

Gyro sensor/Gyro Voltage: Shake the vehicle to the left and right to check that the voltage changes.

Gyro sensor/Relative bearing: Normal when the value changes when direction of the vehicle is changed.

Inclined angle sensor/relative angle: Park the vehicle on uphill or downhill surface. Normal when the value changes.

Gyro/Distance correction study situation: Study situation can be checked.

Reset: Press and hold the Reset button for three seconds to reset the pulse count of SPD, relative bearing of Gyro sensor, relative angle of inclined angle sensor.

GPS: Normal when longitude and latitude of the current position are indicated.

Pull parking brake lever. Check that ON is displayed in PKB.

ON: Normal.

OFF: Abnormal. Check the signal line and connector. If no faulty is found, the unit itself may be faulty.

Bright: Status of the Bright signal input can be checked.
