BOGIE AS 7T0374 - Caterpillar

Problems with the electronic control system are reported via these types of codes: flash codes, diagnostic codes and event codes.Note: Flash codes can represent more than one diagnostic code. Therefore, do not use flash codes to troubleshoot a problem.Flash codes are used to represent diagnostic codes in the electronic system in order to alert the operator that a problem exists. The flash codes are a two digit number. A series of flashes represents the flash code on the diagnostic lamp.EXAMPLENote: Flash code 27 would flash on the diagnostic lamp in the following manner.
Two flashes
Hesitation
Seven flashesFor information on diagnostic codes, refer to Troubleshooting, "Diagnostic Trouble Codes".For information on event codes, refer to Troubleshooting, "Event Codes".Use Table 1 as a cross-reference between the various types of codes.
