# Service bulletin 09\-031\-22

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: 10218734
- Published by NHTSA: 2022\-09\-06
- Manufacturer's number: 09\-031\-22
- Manufacturer's date: 2022\-08\-18
- NHTSA component: ELECTRICAL SYSTEM; ELECTRICAL SYSTEM: INSTRUMENT CLUSTER/PANEL

## NHTSA's summary

Some vehicles may exhibit the “Check Fuel\-filler Cap” message displayed in the instrument cluster. This is caused by improper control software of the PCM. When the room fuse is installed and i\-stop is activated, the message will display in the instrument cluster for three seconds only one time and no message will return. To eliminate this concern, the control software of the PCM has been modified.

- [09\-001\-24b](/bulletins/10252503.md), 2024-04-03, Service bulletin: ELECTRICAL SYSTEM: INSTRUMENT CLUSTER/PANEL. Some customers may experience a “Telematics Malfunction” message in the instrument cluster with DTC U3000:04\-TCU \(Telematics communication unit internal malfunction\) stored in memory. This is caused by improper control software of the telematics communication unit \(TCU\). To eliminate this concern, the control software of the TCU has been modified.

- [07\-002\-23](/bulletins/10232300.md), 2023-03-03, Service bulletin: ELECTRICAL SYSTEM; ELECTRICAL SYSTEM: INSTRUMENT CLUSTER/PANEL. Some customers may complain that the ambient temperature on the instrument cluster is displayed more than 50 °F \(10°C\) lower than the actual temperature, resulting in insufficient performance of the air conditioning. This is caused by inappropriate soldering in the ambient temperature sensor. To eliminate this concern, the soldering process has been enhanced since December 2021 at the supplier.
