U0469 severity depends on the affected system. While some communication errors are intermittent, others can cause system failures. Professional diagnosis is recommended.

Can I drive with U0469?

Short trips may be possible depending on which system is affected. However, if warning lights are on or vehicle behavior is abnormal, have it inspected before driving.

Will U0469 clear itself?

U0469 may clear if the fault is intermittent, but it will likely return if the underlying wiring or module issue is not resolved. Use a scan tool to monitor pending and confirmed codes.

U0469 - Invalid Data Received From Active Safety Control Module 32

U0469 is a Diagnostic Trouble Code (DTC) in the Network Communication (U) category. It indicates invalid data received from active safety control module 32. These codes relate to the vehicle's onboard communication network (CAN bus, LIN bus, etc.) and module-to-module data exchange. When U0469 is set, it means one or more control modules have detected a communication fault, data integrity issue, or software incompatibility on the vehicle network.

What is U0469?

U0469 is a Diagnostic Trouble Code (DTC) in the Network Communication (U) category. It indicates invalid data received from active safety control module 32. These codes relate to the vehicle's onboard communication network (CAN bus, LIN bus, etc.) and module-to-module data exchange.

When U0469 is set, it means one or more control modules have detected a communication fault, data integrity issue, or software incompatibility on the vehicle network.

Common Symptoms

Erratic operation of affected system
Incorrect readings on display
System malfunction warnings
Intermittent operation
Check Engine Light on

Possible Causes

Faulty sending module
Corrupted data transmission
Wiring interference
Voltage spikes on bus
Module internal fault

Step-by-Step Diagnosis

Connect a professional-grade OBD2 scanner and check for all active and pending U-codes.
Identify which modules are communicating and which are not.
Check power, ground, and communication wiring for the Active Safety Control Module 32 using a wiring diagram.
Perform a voltage drop test on power and ground circuits to the affected module.
Check CAN bus resistance (should be ~60 ohms between CAN-High and CAN-Low).
Use a scan tool to monitor live data from modules that are still communicating.
Perform a wiggle test on wiring harnesses while monitoring for communication recovery.
If a module replacement is suspected, verify correct part number and programming requirements.
Clear codes and retest after repairs.

Recommended Repairs

Repair any damaged wiring, connectors, or terminals. Ensure proper routing and secure mounting.
Clean corroded connector pins with electrical contact cleaner.
Replace blown fuses and verify correct amperage rating.
If a module requires programming, ensure it is done with the correct software version.
Update or reflash module software if a TSB applies.
Replace failed control module if testing confirms internal failure.
Verify all repairs by checking module communication with a scan tool.
