DTC 51

CIRCUIT DESCRIPTION




DETECTING CONDITIONS
*1: Since the relief pressure of the compressed air is 980 kPa (10 kg/sq.cm, 142 psi), if vehicle height control is attempted on a steeply sloping road, when the vehicle is overloaded, or when the vehicle jacked up with the engine is running, the compressor motor operated continuously to raise vehicle height, and causes electric current to flow to AIR SUS relay for approx. 7 minutes or longer.
Thus DTC 51 may be output and vehicle height control may be suspended. (This is not abnormal.) However, in this case, when detecting the first error, approx. 10 minutes after the ignition switch was turned ON, vehicle height control is resumed. When detecting the following errors it takes 70 minutes until the control is resumed.
