1. What does Forward Collision System Reduced mean?

“Forward Collision System Reduced” is a Chevrolet OEM alert indicating a reduced forward-collision-related function. Verified GM/NHTSA communications state that it can appear at startup, sometimes with an amber Automatic Emergency Braking Disable icon. A verified bulletin also states the message is normal when Forward Automatic Braking is set to “Alert.”

2. Technical explanation

This is an OEM alert, not a standardized OBD diagnostic trouble code. Verified Chevrolet/GM preliminary-information bulletins PIT5551F, PIT5551H, PIT5551J, PIT5551K, PIT5551L, PIT5551M, PIT5551N, PIT5551P, PIT5551Q, and PIT5551R address reports of a “Forward Collision System Reduced” message in the Driver Information Center (DIC). The bulletins cover vehicles equipped with Forward Automatic Braking and/or Front Pedestrian Braking. The available verified evidence establishes that the warning may be displayed at vehicle startup and may accompany an amber Automatic Emergency Braking Disable icon. PIT5551F and PIT5551H specifically state that the message is normal when Forward Automatic Braking has been set to the “Alert” setting.

3. What system is affected?

Forward Automatic Braking and/or Front Pedestrian Braking. The message is displayed in the Driver Information Center; an amber Automatic Emergency Braking Disable icon may also illuminate in the instrument panel cluster.

4. How serious is this code?

Unknown. Verified evidence does establish that forward collision-related braking functionality may be reduced or disabled as indicated by the warning/icon, but it does not provide a severity classification.

5. Symptoms you may notice

  • “Forward Collision System Reduced” message displayed in the Driver Information Center, including when starting the vehicle.
  • Amber Automatic Emergency Braking Disable icon illuminated in the instrument panel cluster.

6. Possible causes

  • Forward Automatic Braking has been set to the “Alert” setting; PIT5551F and PIT5551H state that this message is normal in that setting.
  • Other causes are not yet established by verified evidence supplied.

7. Can I still drive the vehicle?

Not yet established by verified evidence. The verified communications describe reduced forward-collision-related function and a possible Automatic Emergency Braking Disable icon, but do not state whether driving is safe.

8. Can I charge the vehicle?

Not yet established by verified evidence.

9. What you can safely do

  • Recognize that Forward Automatic Braking and/or Front Pedestrian Braking may be reduced or disabled while the message or amber disable icon is present.
  • Review the vehicle’s Forward Automatic Braking setting, since verified GM communications state that the message is normal when that feature is set to “Alert.”
  • If the message remains present or an amber Automatic Emergency Braking Disable icon is illuminated, seek Chevrolet dealer evaluation; the supplied evidence does not establish a user repair procedure.

10. Step-by-step troubleshooting

  1. Check whether Forward Automatic Braking is configured to the “Alert” setting. PIT5551F and PIT5551H identify this setting as a normal reason for the message.
  2. Record whether the warning appears at startup and whether the amber Automatic Emergency Braking Disable icon is illuminated. These are the conditions described in the verified communications.
  3. No further diagnostic steps are established by the supplied verified evidence.

11. When to contact service

Contact a Chevrolet dealer or qualified service provider if the message persists and you need the forward collision-related system evaluated. Service urgency is not yet established by verified evidence.

12. What the service center may check

  • Confirm the vehicle is equipped with Forward Automatic Braking and/or Front Pedestrian Braking.
  • Verify the reported condition: a “Forward Collision System Reduced” DIC message and/or amber Automatic Emergency Braking Disable icon, particularly at startup.
  • Check the Forward Automatic Braking configuration, including whether it is set to “Alert.”
  • Additional inspection or testing procedures are not established by the supplied verified evidence.

13. Possible repair or resolution

  • If Forward Automatic Braking is set to “Alert,” the verified bulletins state that the message is normal; a repair is not established by that evidence.
  • For other circumstances, a repair resolution is not yet established by verified evidence.
