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 tension of a signal at a stop differs from tension of a signal when driving, this KDN is deduced.

Thus, this KDN can be deduced, when the vehicle is lifted also its wheel (and) rotate. In that case dump KDN and check again.

  • When the G-sensor on 2WD vehicle is established, this KDN is deduced.
  • When the chain of a lamp of 4WD is opened or short-circuited on the earth, this KDN is deduced.
