2 Faulty ECM
Diagnosis and Repair:
1 CAN datalink failure
a Reset the Keyswitch manually.
a Put the generator set control in the OFF position and press the Reset button on the operator panel. This action will clear any shutdown faults and resets the Keyswitch.
b Enable the Keyswitch through the operator panel. Go to Test > Output > Engine > Keyswitch Driver Override Enable, set to Enable.
b Reset the ECM and PCC controls.
a Push the Emergency Stop button in.
b Wait 30 seconds.
c Disconnect the battery terminals from the battery.
d Wait 10-15 seconds.
e Reconnect the battery cables to the battery terminals correctly.
f Pull the Emergency Stop button out.
g Press the Fault Reset button.
c Check the relay that is proving power to the Keyswitch. This relay is normally open, and if faulty, replace.
d Check the terminating resistors. With connectors J11 and J26 removed, measure
resistance between pins J11-19 and J11-20 (60 ohms, is satisfactory).
e Reference the troubleshooting procedure for event/fault code 781 in the engine service manual.
2 Faulty ECM
a After ensuring that the ECM has an adequate B+ supply, connect to the ECM with InPower or Insite in order to determine if it is functioning correctly and can communicate with the PCC controller. Replace the controller if communication to it with InPower is not possible.
Refer to the engine manual for correct threshold values and make the appropriate changes using InPower v14.5 pro.
