# Service bulletin SC243\_TSB\_R1

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: 10222831
- Published by NHTSA: 2022\-11\-02
- Manufacturer's number: SC243\_TSB\_R1
- Manufacturer's date: 2022\-10\-04
- NHTSA component: ELECTRICAL SYSTEM; FORWARD COLLISION AVOIDANCE

## NHTSA's summary

VOLUNTARY SERVICE CAMPAIGN: FRONT RADAR FCA/SCC MISDETECTION PREVENTION LOGIC IMPROVEMENT \(SC243\) \- This bulletin has been revised to include additional information. New/revised sections of this bulletin are indicated by a black bar in the margin area. This bulletin provides information to update the software logic of the Front Collision\-Avoidance Assist \(FCA\) and Smart Cruise Control \(SCC\) system on certain 2020\-2022MY Telluride \(ON\) vehicles listed below. If foreign material, snow/ice, or roadway debris blocks the front radar located in the front bumper area, misalignment may occur, causing improper obstacle detection by the FCA system without illumination of the FCA warning lamp. If this condition occurs, the vehicle may apply partial braking when passing other vehicles. This update is to adjust the FCA warning lamp strategy and set conditions to improve the detection of a front radar misalignment condition.

- [PS797](/bulletins/11026698.md), 2025-12-18, Other: BACK OVER PREVENTION: WARNINGS. PITSTOP: TECHNICAL OPERATIONS: EXTERNAL DAMAGE TO ULTRASONIC SENSOR: This Pitstop provides information related to Parking Distance Warning \(PDW\) alerts and repairs involving ultrasonic sensors. The PDW system alerts the driver while parking, by calculating distance based on the difference in signal transmission and reception times between the vehicle \(ultrasonic sensor\) and an object. The membrane film of the ultrasonic sensor is used for object detention and can be damaged by stone chips or foreign substances while driving. Damage to the cover of the ultrasonic sensor can also lead to damage to the internal circuit. As a result of this external damage, the PDW system may not receive the proper signal from the ultrasonic sensor. In some cases, the system may cause a false alarm, no alert, or phantom warnings by a “Warning Lamp’ to be displayed on the cluster. The ultrasonic sensor membrane film should be always inspected for external damage and if any part replacement should be treated as a general repair, not as a warranty claim repair for this concern. \(Please note that this Pitstop only applies to models/trims that are equipped with the ultrasonic sensors.\)
- [PS793](/bulletins/11021406.md), 2025-08-05, Service bulletin: ELECTRICAL SYSTEM. This Pitstop provides information regarding an inoperative sunroof switch on 2020–2025MY Telluride \(ON\) vehicles. When diagnosing a vehicle for this condition, check that connectors R02 and R03 are connected in the correct cavities. If these connectors were previously interchanged unintentionally, the sunroof switch will not operate.
