DTC 41

DTC 41 Air SUS Relay Circuit

CIRCUIT DESCRIPTION
When the vehicle height starts to rise, a signal is sent from terminal RC of the ECU to switch the AIR SUS relay on. As a result, current 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 DTC 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.
