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 short flashes
Hesitation
Seven short flashesNote: Flash codes can represent more than one diagnostic code. Make a note of all of the diagnostic codes that are represented by a particular flash code.After the diagnostic codes have been determined, refer to Troubleshooting, "Table of Contents" in order to determine the page that represents the diagnostic code.
