C7.1 Industrial Engine Caterpillar


Diagnostic Flash Code Retrieval

Usage:

C7.1 770
In order to read the diagnostic flash codes through the diagnostic lamp, cycle the key switch from off to on twice within 3 seconds.

The codes will be flashing in sequence. For example if the flash code equals 133, the diagnostic lamp will flash once, pause, flash three times, pause, and flash three times.

After the complete code has flashed, a 3 second pause will take place before the next code will begin to flash (if another code is present).

Note: For more information refer to Troubleshootingmanual.
