INSPECTION PROCEDURE

PROCEDURE

1.

CHECK ZERO POINT CALIBRATION OF YAW RATE (DECELERATION) SENSOR

(a) Move the shift lever fo the P position and turn the ignition switch ON. Repeat connecting and releasing TS and CG terminals of the DLC3 4 times or more for 8 seconds. After this, turn the ignition switch OFF and after connecting terminals TS and CG, turn it ON again.
