DTC 41

When raising of the vehicle height starts, a signal is sent from terminal RC of the ECU to switch the AIR SUS relay on. As a result, curent flows to the AIR SUS relay coil, the contacts in the relay close, and thus battery positive voltage is applied to the compressor, the compressor produces compressed air.

Once the ECU stores diagnostic trouble code 41 in memory, vehicle height control is not carried out until a normal signal is input to the ECU from the AIR SUS relay.

However, control is resumed if the ignition switch is turned off, then on again.
