Problems with the electronic control system are reported via these types of codes: flash codes, SPN/FMI codes, diagnostic codes, and event codes.

For information on flash codes, refer to troubleshooting with a diagnostic code Troubleshooting, "Flash Codes".

For information on SPN/FMI codes, refer to troubleshooting with a diagnostic code Troubleshooting, "Diagnostic Codes".

For information on diagnostic codes, refer to troubleshooting with a diagnostic code Troubleshooting, "Diagnostic Codes".

For information on event codes, refer to troubleshooting with an event code Troubleshooting, "Event Codes".

Cross-Reference for Flash Code to SPN-FMI Code to CID-FMI (Diagnostics) or EID (Events)
