What it means
A receiving module detected implausible data from the driver information center B (instrument cluster information area). Display state or warning indicator data fails plausibility checks and is rejected.
How it works
Information Center B is an instrument-cluster information area that shares display or warning-indicator status with other modules. U0458 is set when a receiving module considers that information implausible and rejects it; the fault concerns area B, which can help distinguish it from a problem limited to area A.
Common causes
Most likely first.
- Module internal fault or sensor input drift
- Software version mismatch after replacement
- Gateway module routing CAN messages incorrectly
Symptoms
- Multiple warning lights may illuminate
- Affected modules may go into limp mode or shut down
- Specific functions inoperative depending on module
- Diagnostic tools may show communication faults
How to diagnose it
- Scan the instrument cluster and other modules for U0458 and related display or network codes, and save freeze-frame details.
- Note which messages, indicators, or display functions fail and whether the issue affects information area B only.
- Check the cluster for recent replacement, programming, battery, or accessory work that may have disturbed configuration or power.
- Inspect accessible cluster connectors and network wiring for looseness, corrosion, or damage.
- Use a scan tool to compare information-center B status data with what the cluster actually displays and check whether information center A is also affected.
- Verify configuration and software compatibility after any module replacement, then follow manufacturer procedures to test the cluster and network.
Common fixes
- Reconnect or repair a damaged cluster connector or network wire.
- Correct instrument-cluster configuration or software incompatibility.
- Repair the affected display area or cluster if its reported status fails manufacturer tests.
- Repair a gateway or network fault if multiple modules receive invalid cluster data.
Can I keep driving?
Driving may be reasonable if essential gauges and warning lamps work, but do not continue if you cannot reliably see speed, fuel, or critical warnings. Have the fault checked if the display or safety alerts are affected.
A code shows where the control module detected a fault, not always which part failed. Check the causes in order and confirm with a test before replacing parts. Have several codes? Check them together
This is a generic code: it means the same on every make. The car’s maker may add more detail in its own service information.
