There’s a fault in the active park assist system.
Heads up: this code wasn't in our hand-written library yet, so DiagCoach AI built this page on the fly. Double-check critical specs against service info before condemning parts.
What it means (plain English)
The active park assist system is having trouble, which means it might not help you park as it should.
What the computer is actually seeing
The park assist module is reporting a malfunction, indicating that it cannot reliably process sensor data.
What a healthy reading looks like
The module expects to receive consistent signals from the ultrasonic sensors with a voltage of around 5V when activated, and no gaps in communication are allowed.
Guided diagnostic — the DiagCoach way
Don't just throw parts at it. Walk through these in order — each step tells you whether to keep going or stop and fix what you found.
- 11. Check the wiring and connectors for the park assist sensors for corrosion, damage, or loose connections. If any faults are found, repair or replace as necessary. Decision: If wiring is intact, proceed to step 2; if damaged, fix it and clear the code to see if it returns.
- 22. Test the ultrasonic sensors using a scan tool to ensure they are functioning correctly. You should see expected voltage readings around 5V. Decision: If sensors are faulty, replace them. If readings are normal, proceed to step 3.
- 33. Inspect the park assist module for any obvious damage or faults. If the module shows burn marks or other visible damages, replace the module. If it appears fine, confirm that all other modules in the system are communicating properly.
Common causes
- Faulty ultrasonic park assist sensors
- Bad wiring or connectors in the park assist circuit
- Faulty active park assist module
