# Service bulletin SS3070FTL2021

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

- Type: Service bulletin
- NHTSA id: 10189337
- Published by NHTSA: 2021\-03\-25
- Manufacturer's number: SS3070FTL2021

## NHTSA's summary

Service Solution for P4 New Cascadia Side Guard Radar Harness Moisture Intrusion. The 6\-pin connector located at the side radar can show signs of water intrusion if wires are strained at the connector. Wires without strain relief can allow water to intrude past the seals, resulting in corrosion on the terminals and pins within the connector. Active fault codes for lost communication with RDU and SRRM, plus other codes for CPC, CGW and ABS.
