WASHER 4415647 - Caterpillar

Which Generate This Code:The following conditions occur:443-1
The engine has been running for three minutes.
There are no active diagnostic codes for the auxiliary pressure sensor.
The pressure that is sensed by the auxiliary pressure sensor has exceeded the set point for four seconds.Note: The warning will be cancelled if the pressure falls 40 kPa (6 psi) below the set point for two seconds.443-2
The engine has been running for three minutes.
There are no active diagnostic codes for the auxiliary pressure sensor.
The pressure that is sensed by the auxiliary pressure sensor has exceeded the set point for three seconds.Note: The derate will be cancelled if the pressure falls 40 kPa (6 psi) below the set point for two seconds.443-3
The engine has been running for three minutes.
There are no active diagnostic codes for the auxiliary pressure sensor.
The pressure that is sensed by the auxiliary pressure sensor has exceeded the set point for three seconds.System Response:443-1The warning lamp will flash while the warning is active.The ECM will generate a E443-1 event code.The ECM will generate a SPN 1835-FMI 15 event code on the J1939 data link. The event code may be displayed on a receiving device on the J1939 data link.443-2The warning lamp will flash while the derate is active.The ECM will generate a E443-2 event code.Caterpillar Electronic Technician (ET) will display "Engine Derate" in the first "Engine Status" box on any Cat ET status screen.The ECM will generate a SPN 1835-FMI 16 event code on the J1939 data link. The event code may be displayed on a receiving device on the J1939 data link.443-3The warning lamp will flash.The ECM will generate a E443-3 event code.The ECM will generate a SPN 1835-FMI 00 event code on the J1939 data link. The event code may be displayed on a receiving device on the J1939 data link.443-1Engine operation is not affected.443-2The ECM will derate power by 25 percent. The power will be derated at one percent per second.443-3The engine will shut down.Test Step 1. Verify that the set points are valid for the application.Determine the events that caused the high pressure condition. Make corrections in order to prevent the high pressure from recurring.Results:
OK - STOP
