## Other bulletins for the same vehicles and component

- [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.
- [09\-001\-24a](/bulletins/10251361.md), 2024-03-06, 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.
- [09\-003\-24](/bulletins/10249501.md), 2024-02-01, Service bulletin: EQUIPMENT; ELECTRICAL SYSTEM; ELECTRICAL SYSTEM: INSTRUMENT CLUSTER/PANEL. Some vehicles may experience the opening sequence of the instrument cluster is not displayed after IG\-ON. NOTE: Opening sequence of the instrument cluster refers to the display that occurs immediately after ignition is turned on. The vehicle model's logo is shown on the instrument cluster's LCD screen before transitioning to the speedometer display. The sequence also swings the analog meter needle to its maximum. This concern is caused by improper control software of the BCM. To eliminate this concern, the control software of the BCM control module has been modified. Customers having this concern should have their vehicle repaired using the following repair procedure. NOTE: CSSU regulation compliance: This Service Information provides the software modification and the software information according to United Nations Regulation on Cybersecurity \(CS\) and Software Updates \(SU\).
- [15\-003\-23](/bulletins/10244577.md), 2023-11-01, Service bulletin: ELECTRICAL SYSTEM:SOFTWARE; ELECTRICAL SYSTEM: INSTRUMENT CLUSTER/PANEL. While idling or parking, some customers may experience the i\-ACTIVSENSE warning appears in the instrument cluster and the parking sensor OFF switch in the cluster switch illuminates. Upon inspection, any of the following DTC B1B\*\* are stored in memory.
- [SA\-030\-23a](/bulletins/10237214.md), 2023-06-04, Service bulletin: ELECTRICAL SYSTEM; ELECTRICAL SYSTEM: INSTRUMENT CLUSTER/PANEL. Some customers may experience a warning sound and instrument cluster message "Battery Saving Mode. Drive Vehicle to Charge Battery."
- [SA\-030\-23](/bulletins/10237213.md), 2023-06-04, Service bulletin: ELECTRICAL SYSTEM; ELECTRICAL SYSTEM: INSTRUMENT CLUSTER/PANEL. Some customers may experience a warning sound and instrument cluster message "Battery Saving Mode. Drive Vehicle to Charge Battery."
- [09\-020\-23](/bulletins/10235419.md), 2023-05-03, Service bulletin: ELECTRICAL SYSTEM: INSTRUMENT CLUSTER/PANEL; EQUIPMENT. Some customers may notice white lines appearing across the instrument cluster \(as shown below\). The white lines may be caused during the production process where poor contact occurs at the internal LCD terminals.
- [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.
- [09\-016\-23](/bulletins/10232299.md), 2023-03-03, Service bulletin: ELECTRICAL SYSTEM; ELECTRICAL SYSTEM:INSTRUMENT PANEL:SPEEDOMETER/ODOMETER. Speedometer replacement procedure
- [09\-031\-22](/bulletins/10218734.md), 2022-09-06, Service bulletin: ELECTRICAL SYSTEM; ELECTRICAL SYSTEM: INSTRUMENT CLUSTER/PANEL. 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.
