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.
