Perkins electronic motors are capable of self-diagnosis. When the system registers an active problem, the diagnostic lamp is activated. In this case, the diagnostic codes will be stored in read-only memory (ROM) of the electronic control module ECM. Diagnostic codes can be retrieved using the electronic service tool. For more information, see the chapter Troubleshooting, Electronic Service Tools.
Some installations with electronic displays have the ability to directly read engine diagnostic codes. For more information on retrieving diagnostic codes, see the manual supplied by the OEM (original equipment manufacturer), as well as the Troubleshooting chapter, “Warning Lights” section.
Active codes indicate problems that currently exist. These problems must be investigated first.
Registered codes display the following:
· Occasional malfunctions
· Registered Events
· History of operation
Problems can be fixed since the registration of the code. These codes do not indicate the need for repair, they are landmarks or signals when events occur. Also, these codes can be helpful in solving troubleshooting problems.
After resolving the problem, it is necessary to clear the corresponding registered failure codes.
The diagnostic lamp indicates the existence of an active failure. You can find more detailed information in the chapter Troubleshooting, section “Warning lights”. While resolving an existing problem, the fault diagnosis code will remain active. This diagnostic code can be retrieved using the electronic service tool. You can find more detailed information in the Troubleshooting chapter, Electronic Service Tools section.
Use the Diagnostic lamp or electronic service tool to determine the diagnostic flashing code.
If the engine is equipped with a Diagnostic lamp, use the following algorithm to retrieve the blink code:
1. Change the position of the switch from on / off 2 times within 3 seconds.
The flashing yellow light indicates the digital engine code. The flashing sequence is a diagnostic message from the system. To determine the first digit of a blink code, count the number of blinks in the first sequence. After a two second pause, the second flashing sequence determine the second digit of the flashing code. And finally, after a second pause, the third blink sequence will determine the blink code.
Any additional codes will follow after a pause and displayed in the same way. Flashing code 551 means that since the ignition key was turned to the ON position, no faults were recorded.
