Condition

Some customers may comment on an amber Forward Collision icon displayed in the IPC,
as shown below. Also, DTC U3000 symptom 44, 49, 54, and/or 57 may or may not be set
current in the Front View Camera Module. In some cases, there could be a low or dead
battery condition. Customers may also notice certain features related to the Front View
Camera are unavailable, such as:
– Forward Collision Alert (RPO: UEU)
– Following Distance Indicator (RPO: UE4)
– Low Speed Collision Mitigation Braking (RPO: UHY)
– Pedestrian Collision Mitigation Braking (RPO: UKJ)
– Lane Keep Assist (RPO: UHX)
– Automatic High Beam Assist (RPO: TQ5)
– Adaptive Cruise Control (RPO: KSG)
Note: Because this condition could cause a low/dead battery, it can cause the Auto Stop/
Start feature to be disabled due to the battery start of charge. The front view camera
module issue should be corrected first before diagnosing an auto stop/start concern.

Cause

The cause of the condition may be Onstar performing a task, which causes the B174W
Front View Camera to set the DTC and disable during the next vehicle start up.

Correction

Refer to the Service Procedure below.

GM bulletins are intended for use by professional technicians, NOT a "do-it-yourselfer". They are written to inform these
technicians of conditions that may occur on some vehicles, or to provide information that could assist in the proper
service of a vehicle. Properly trained technicians have the equipment, tools, safety instructions, and know-how to do a
job properly and safely. If a condition is described, DO NOT assume that the bulletin applies to your vehicle, or that your
vehicle will have that condition. See your GM dealer for information on whether your vehicle may benefit from the
information.
