Initial Calibration Of Compass During PDS (PD058-06)

INITIAL CALIBRATION OF COMPASS DURING PDS

TECHNICAL SERVICE BULLETIN

Introduction

The compass indicates the direction that the vehicle is heading by detecting the direction and strength of the Earth's magnetic field and processing this data using the compass sensor and microcomputer.

Detection of the direction and strength of the Earth's magnetic field varies according to the area in which the vehicle is used and is affected by the residual magnetism of the vehicle. For this reason, the geographic direction displayed may also deviate from the direction determined by the Earth's magnetic field according to the area in which the vehicle is used.

Perform the initial calibration of the compass at the dealership prior to vehicle delivery.

Applicable Vehicles

• 2007  model year GX 470  vehicles.

3. Start the engine and push and hold the switch for about 9 seconds until "C" appears on the display.

4. Drive the vehicle slowly at 5 mph (8 km/h), or less, in a circle until the direction is displayed. If there is NOT enough space to drive in a circle, turn the car around as shown, doing two three-point turns in succession.

   After driving in 1 to 3 circles in the above method, calibration is complete with the direction shown on the display.

   NOTE:

   • Do NOT perform calibration of the compass in a place where the Earth's magnetic field is subject to interference by artificial magnetic fields (underground parking, under a steel tower, between buildings, roof parking, near a railroad crossing, near a large vehicle, etc.)
   • During calibration, do NOT operate electric systems (moon roof, power windows, etc.) as they may interfere with the calibration.
