TSB Document:

Affected Component: FORWARD COLLISION AVOIDANCE: SENSING SYSTEM: CAMERA

Summary
Some vehicles may exhibit DTC U2120:00 and/or U2500:82 stored in memory and the i-ACTIVSENSE warning light (amber) ON when turning ON the ignition after any electronic control unit (ECU) is reprogramed or configured using MDARS. NOTE: ECU stands for general units (cameras and modules), all of which can be reprogrammed. This is caused by a software malfunction of the forward sensing camera (FSC). To correct this issue, the FSC software will be modified.
