"Diagnostic" Lamp
Use the "DIAGNOSTIC" Lamp or a Caterpillar electronic service tool to determine the diagnostic flash code.Use the following procedure to retrieve the diagnostic codes if the engine is equipped with a "DIAGNOSTIC" lamp:
Turn the ignition key to the ON position. The engine does not need to be started in order to view codes. The engine does not need to be running while the ignition switch is in the ON position. The "DIAGNOSTIC" lamp blinks on and off at five second intervals.
When the ignition key is in the ON position, the lamp is checked for proper operation. If there are any active codes except for code 34, the codes are displayed at this time.Note: The "DIAGNOSTIC" lamp will illuminate for five seconds. The lamp will stay on if there is an active diagnostic code.
The diagnostic codes will always be flashed. There is no toggle switch that will shut off the lamp.
The "DIAGNOSTIC" lamp will flash in order to indicate a two-digit code. The sequence of flashes represents the system diagnostic message. Each digit of the two-digit code is determined by counting the number of flashes. The lamp flashes at a rate of two times per second. The lamp will pause for one second between digits. The lamp will pause for two seconds between codes. Table 1 indicates the potential effect on the engine performance with active flash codes. Table 1 also forms a list of electronic diagnostic codes and descriptions.
