KDN 15 (KDN OF THE C 1015)
Chain of a G-sensor and chain of 4WD
Description
When the vehicle stops or goes if the difference of potentials between a conclusion of a signal of a sensor of "A 14" and a conclusion of grounding of a sensor of "A4" does not correspond to the established value of tension or if signal tension at a stop differs from signal tension when driving, this KDN is removed.
Thus, this KDN can be removed when the vehicle is lifted and its wheel (a) rotate. In that case dump KDN and check again.
When the G-sensor is installed on the vehicle 2WD, this KDN is removed.
