Claims (1)
する車高センサと、この車高センサから出力され
るｎビツトの特定ビツトが「０」である複数の車
高信号間の変位を計数し、その計数値が設定値以
上の場合には、車高センサの断線エラーであると
する断線検出手段とを具備したことを特徴とする
車高センサの故障検出装置。 A vehicle height sensor that detects an n-bit vehicle height signal corresponding to the vehicle height, and a displacement between multiple vehicle height signals in which the n-bit specific bit output from this vehicle height sensor is "0" is counted. A failure detection device for a vehicle height sensor, comprising: disconnection detection means that detects a disconnection error in the vehicle height sensor when the counted value is equal to or greater than a set value.
