Need help with fault code

I did a quick google search on that SPN, but only found "unspecified error - contact manufacturer". There was a recall on the Cascadia SAM chassis because of potential water intrusion. Call a dealer and give them that SPN, then ask about the recall.

 

is it SPN 520920 FMI 05 ? if yes read this :

Stop lamp right -
Current below normal, or open circuit

No load is connected If stop lamps are used as turn signals, right turn signals are flashing at twice the normal frequency

1. The wiring harness to the connected load is open

2. The connected load is not functioning properly
***********************

1. Check the wiring harness to the connected load
2. Check load
