U05A7: Invalid Data Received From Safety Integration Control Module

What it means

A receiving module detected implausible data from the safety integration module that arbitrates between ADAS, restraint, brake and steering systems. Cross-system safety status values fail plausibility checks and are rejected.

At a glance

• Usually lights the warning light of the system that lost communication
• The engine or gearbox may go into limp mode

How it works

The safety integration control module coordinates status information shared among driver-assistance, restraint, brake, and steering systems. This code sets when another module receives cross-system safety status values from it that fail plausibility checks and rejects them; related safety features may then be disabled or restricted.

Common causes

Most likely first.

1. Module internal fault or sensor input drift
2. Software version mismatch after replacement
3. 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

1. Record freeze-frame data and scan the safety integration, restraint, brake, steering, and ADAS modules for related faults before clearing codes.
2. Check which safety status messages are missing or implausible in live module data and note any disabled functions or warnings.
3. Inspect the safety integration module and gateway connectors and CAN wiring for damage, corrosion, loose pins, or poor grounds.
4. Check the affected brake, steering, restraint, or ADAS modules for their own sensor or communication faults that could create inconsistent status reports.
5. Verify compatible software and configuration across the safety integration module, affected modules, and gateway, particularly after repairs or replacement.
6. Use manufacturer-approved network diagnostics to isolate a routing fault or a faulty safety integration, receiving, or gateway module.

Common fixes

• Repair damaged or corroded safety-module connectors, grounds, or CAN wiring.
• Resolve a related sensor or communication fault in the affected brake, steering, restraint, or ADAS system.
• Correct module software or configuration incompatibility after replacement or programming.
• Replace a safety integration module, gateway, or receiving module only after network testing confirms it is faulty.

Can I keep driving?

Because this fault can disable or limit braking, steering, restraint, or driver-assistance functions, do not rely on affected safety features and avoid driving if brake or steering warnings appear. Have the vehicle assessed promptly; arrange recovery if basic braking or steering is impaired.
