• The remaining AdBlue® level is calculated as follows:
Remaining AdBlue® level decreased
1. The remaining AdBlue® level amount is calculated by the SCR control unit based on the specified injection volume.
2. The calculated amount in 1) is corrected by the three urea level sensor signals installed in the urea tank.
Urea supply replenished
1. The urea level sensor signal and the remaining amount recorded in the SCR control unit are compared to determine whether or not urea has been replenished.
2. The remaining amount after replenishing the urea is calculated based on the urea level sensor signal.
• The urea level sensor detects the AdBlue® level based on the resistance value.
• The SCR control unit sends the calculated remaining AdBlue® level amount to the CAN.
