Flash Codes

Usage:

3126B 3GS
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 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.

EXAMPLE

Note: Flash code 27 would flash on the diagnostic lamp in the following manner.

  • Two flashes

  • Hesitation

  • Seven flashes
