U11A0 Jeep Code - Lost Communication With Center Pedestrian Protection Satellite Acceleration Sensor
Quick Answer
The pedestrian protection impact sensors perform their own self-test using power supplied by the Electronic Pedestrian Protection module (EPPM) then communicate this status back to the EPPM with periodic updates. Common causes include Faulty Center Pedestrian Protection Satellite Acceleration Sensor, Center Pedestrian Protection Satellite Acceleration Sensor harness is open or shorted, Center Pedestrian Protection Satellite Acceleration Sensor circuit poor electrical connection. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

Code U11A0 Jeep Description
This Diagnostic Trouble Code (DTC) sets when the EPPM no longer receives the notification of the status update from the Center Pedestrian Protection Satellite Acceleration Sensor. Once set, this DTC is latched for the entire ignition cycle. This code will set active if the loss of communication with the sensor has lasted for more then 2.5 seconds. This fault is latched for the full ignition cycle. The fault will go stored on the next key cycle upon the fault not setting for longer than 2.5 seconds.
What are the Possible Causes of the DTC U11A0 Jeep?
- Faulty Center Pedestrian Protection Satellite Acceleration Sensor
- Center Pedestrian Protection Satellite Acceleration Sensor harness is open or shorted
- Center Pedestrian Protection Satellite Acceleration Sensor circuit poor electrical connection
- Faulty Electronic Pedestrian Protection Module (EPPM)
