WEDGE-TRACK CAP 1098014 - Caterpillar

Flash codes are a simple way to alert the operator that a problem exists with the engine's control system or with the engine's operation. Each flash code is a two digit number. The diagnostic lamp flashes in order to identify the flash code.For more information on flash codes, refer to Troubleshooting, "Flash Codes".
