SYSTEM NAME Variable Gear Ratio Steering System Meter / Gauge System 1. STEERING ANGLE SENSOR INITIALIZATION (a) Turn the ignition switch ON and check that the VGRS and VSC/TRAC warning lights illuminate for a few seconds. NOTICE: If the warning lights remain on or blink, repair the applicable system. (b) Drive the vehicle on a straight road at 35 km/h (22 mph) or more for 5 seconds or longer.
At this point, the steering wheel will still remain off-center by 5 to 10 degrees. HINT: In this step, the neutral position of the steering wheel is restored from the VGRS ECU memory. (c) After performing normal cornering 2 to 3 times, the steering wheel position is automatically corrected. NOTICE: If the steering wheel remains off-center after the above procedure, repair the applicable system. (d) Confirm that the steering angle sensor initialization is completed. WHEN USING INTELLIGENT TESTER: Use this procedure to center the steering wheel when the STRAIGHT ANG FLG from the VGRS DATA LIST reads VALID. WHEN NOT USING INTELLIGENT TESTER:
(1) Drive the vehicle on a road at 60 km/h (37 mph) or more for 30 seconds or longer. HINT: At this time, if the steering angle initialization is not completed, the VGRS system is stopped. (2) Stop the vehicle with the engine running. (3) Slowly turn the steering wheel from lock to lock. HINT: Allow 2 seconds or more for 1 turn. (4) If it rotates approximately 2.4 turns, the steering angle sensor initialization is completed. If it rotates approximately 3.5 turns, the steering angle sensor initialization is not completed. 2. RESET COMPASS IN COMBINATION METER (a) SELECTING COMPASS DISPLAY MODE The mode select switch allows you to select a display or non-display mode of the compass.
The mode select is operated by the automatic glare-proof / non-glare proof switch on the inner mirror. (b) PERFORMING CALIBRATION Because each vehicle has its own magnetic field, calibration should be performed for each vehicle. This compass function is used when storing the record o the vehicle's magnetic field. (c) WHEN COMPASS MAGNETIZED A compass could be magnetized during shipping by vessels or freight cars. Before delivery, therefore, make sure to perform calibration and ensure that calibration can be done. If calibration cannot be completed despite driving the vehicle in a circle several times, the vehicle's magnetic field may be interfering with the calibration.
Demagnetize the vehicle using a demagnetizer and perform calibration again. cardi
