Diagnostic Codes Table    
Description    Conditions which Generate this Code    System Response    
1440-9 Throttle Actuator : Abnormal Update Rate     The ECM has lost the last ten messages that were expected from the actuator for the throttle over the CAN data link.     The code is logged.
The alarm output is activated.
The shutdown output is activated.
The engine is shut down.    
1446-9 Fuel Metering Module : Abnormal Update Rate     The ECM has lost the last ten messages that were expected from the fuel metering valve over the CAN data link.     The code is logged.
The alarm output is activated.    
1720-9 Turbocharger Compressor Bypass Valve Actuator : Abnormal Update Rate     The ECM has lost the last four messages that were expected from the compressor bypass actuator over the CAN data link.     The code is logged.
The alarm output is activated.
The shutdown output is activated.
The engine is shut down.    
3002-9 Engine Exhaust NOx Level Sensor : Abnormal Update Rate     The ECM has lost the last ten messages that were expected from the NOX level sensor over the CAN data link.     The code is logged.
The alarm output is activated.    The CAN data link is used to communicate information between the master ECM and other control modules that are on the engine. Use this procedure to troubleshoot any suspect problems with the CAN data link.This procedure identifies the following problems:
Faulty connectors
Missing termination resistors
Short circuits
Open circuits
Faulty display panelA -9 code that is related to any specific control module may be caused by the power supply circuit to the control module. Be sure to check that the suspect control module is receiving the power before you troubleshoot the circuit for the CAN data link. If you suspect that a power supply circuit may be the cause of the -9 code, refer to the circuit test for the suspect control module and troubleshoot the problem.A problem with the CAN data link is probably caused by a short circuit to ground, an open circuit, or a short circuit to another voltage source in the harness. The next likely cause is a problem with a control module that is connected to the data link. The least likely cause is a problem with the ECM.
