Flash Code Index

WARNING LAMP FLASH CODE CHART

How to read flash codes

Put the vehicle in Diagnosis Mode. Refer to Trouble Diagnosis without CONSULT.
All codes are proceeded by a seven second “holding” flash.
Identify how many primary flashes are displayed as well as the length of each primary flash.
Refer to the tables and examples below to determine which SRS subsystem the code belongs to.
Count the short secondary flashes that follow the primary flashes.
Match the correct flashing pattern to the malfunctioning component and perform the Diagnosis Procedure.

Refer to the illustrations below for an example of each flashing pattern.
