DTC 52

CIRCUIT DESCRIPTION:
If the vehicle height control is operated while removing the wheels or when jacking up the car, DTC 52 may be output. This is not abnormal. When DTC 52 is output, vehicle height control is not carried out. However, control is resumed if the ignition switch is turned OFF, the ON again, or the removing of the wheels or jacking up of the vehicle is cancelled. Code 52 is set when electric current is applied to the exhaust valve, which decreases vehicle height, for 6 minutes or longer. Inspect the ECU, height control sensor, height control link, air tube, exhaust valve and the height control valve.
