U0492: Invalid Data Received From Television

What it means

A control module received invalid data from the television module. The code identifies a data validity fault; the specific affected function depends on the vehicle.

How it works

The television module supplies TV-related content or status to the vehicle’s infotainment system and communicates that information over the network. U0492 sets when another control module receives data from the television module that fails validity checks.

Common causes

Most likely first.

1. Fault in the transmitting module
2. Network wiring or connector fault
3. Module power or ground fault
4. Software or configuration mismatch

Symptoms

• Television or related infotainment functions may not work correctly
• Infotainment warning or related communication codes may appear

How to diagnose it

1. Scan all modules and record freeze-frame information, identifying the module that logged U0492 and any television, infotainment, or network codes.
2. Check whether TV-related content, source selection, or status displays fail while other infotainment sources work normally.
3. Inspect the television module’s connector and accessible network wiring for loose connections, corrosion, water entry, or damage.
4. Check the television module’s power and ground according to the manufacturer’s procedure.
5. Review its reported status with a vehicle-capable scan tool and check for software or configuration mismatch, especially if the module was recently replaced.
6. If wiring and supply are good, use the manufacturer’s network diagnostics to distinguish a television module fault from a gateway routing problem.

Common fixes

• Secure or repair a loose, corroded, or damaged television module connector or network wire.
• Repair the module’s power or ground connection.
• Correct software or configuration after module or infotainment replacement.
• Replace the television module or repair the gateway only when testing identifies the source of the invalid data.

Can I keep driving?

A fault limited to TV or infotainment functions generally does not affect driving. If other modules show warnings or lose functions, investigate those symptoms promptly.
