Auto lights won't turn off on a 2011 Chevy Traverse even after 10 minutes


Well Jeni there are a few thing's that could be wrong , the headlamp switch , the BCM -body control module -a electronic control module . There are relays involved also ,but don't think there at fault . To be sure you need to do some electrical test to know for sure ! I suggest you take it to a ASE certified repair shop that has the knowledge , tools an service info - wiring diagrams etc.. ! Oh and a scan tool that can extract DTC'S from the BCM there could be a diagnostic trouble code pointing to the problem !

1. Headlamps Always On

2. Headlamps Inoperative From Switch

3. Unable To Turn OFF Automatic Headlamps

4. Park Lamps Inoperative From Switch

5. Park Lamps Always On
When the headlamp switch is in the OFF position, the body control module (BCM) receives a ground signal through the headlamp switch OFF circuit and an open signal on the park lamp ON circuit and headlamps ON circuit. When the headlamp switch is in the PARK or HEAD position, the BCM receives an open signal through the headlamp switch OFF circuit and a ground signal through the park lamp ON circuit or headlamp ON circuit.
Circuit/System Testing

  1. Ignition OFF, disconnect the harness connector at the headlamp switch.
  2. Verify that a test lamp illuminates between the ground circuit terminal 8 and B+.
  3. ?‡'
    If the test lamp does not illuminate, test the ground circuit for an open/high resistance.

  4. Ignition ON, verify the scan tool Auto Hdlp. Disable Sw. parameter is Inactive.
  5. ?‡'
    If not the specified value, test the signal circuit terminal 3 for a short to ground. If the circuit tests normal, replace the BCM.

  6. Verify the scan tool Headlamp Switch parameter is Inactive.
  7. ?‡'
    If not the specified value, test the signal circuit terminal 1 for a short to ground. If the circuit tests normal, replace the BCM.

  8. Verify the scan tool Parklamp Switch parameter is Inactive.
  9. ?‡'
    If not the specified value, test the signal circuit terminal 2 for a short to ground. If the circuit tests normal, replace the BCM.

  10. If all circuits test normal, test or replace the headlamp switch.
If the BCM needs to be replaced , it has to be programmed . The dealer is pretty much the only place to have that done at ! There are other places ,you have to look in the phone book or inquire at local repair shops . Some towns ,city's have mobile repair guy's that do flash programming of modules etc... Good luck hope I gave you some insight on the problem ! I tell people these thing's an it's like they don't believe me , I see they repost the same question . I started working as a Technician in 1984 at a Chevy dealer ship an have worked at Cadillac , Pontiac , GMC dealer ships ! I see all to often people trying to fix these type of problems by just replacing parts not knowing what they are doing an wasting there money an later bring it to the shop anyway ! So I hope you make a good decision an take to a qualified repair person or shop !

Service park assist message. I replaced all 4 sensors and wiring harness at bumper. Vehicle was never in accident.


I not sure what the problem is but I do know if you back up over five miles per hour the park assist will shut down in reverse and you will get a message to that effect on the dash. I had the same problem with one of mine and the dealer told me that it is designed that way to shut down. Try backing up under five miles per hour and see if you have the same problem. Hope this helps.

Hi I don't know the vehicle but sounds as if the park assis on all the time not turning off see if your reverse lights are working correctly, may be getting a feed buck into the unit keeping it turned on.

It sounds like the repair is not complete. I would suggest taking it to first the place that did the repair and if they do not help go to the dealer.

The park assist service light comes on when i start the vehicle. i do not have an owners manual to reference.


{: ) The driver information center (DIC) displays SERVICE PARK ASSIST when the object alarm module detects a malfunction in the parking assist system and the system is disabled. The DIC also displays SERVICE PARK ASSIST when a loss of communication occurs with the object alarm module. Usually this is caused by faulty components or wirings. Better visit your dealer if still under warranty, for one park assist sensor only costs too much. If your bumper had been knocked off or had previous repairs outside the dealership, that's another thing.
The PARK ASSIST OFF message is displayed in the DIC when the parking assist system is disabled due to conditions that disable or inhibit the system. The object alarm module requests the DIC display PARK ASSIST OFF when it detects one of the following conditions:
• The parking assist system is manually disabled using the driver information center (DIC). • An object is attached to the rear of the vehicle, such as a trailer, bicycle rack, trailer hitch receiver, or tow bar. • The object alarm sensors are covered by snow, mud, dirt, slush, or ice. • The vehicle bumper is damaged, • Excessive paint thickness on a replacement object alarm sensor. • The object alarm sensors are disrupted by vibrations, like those caused by a large nearby vehicle or from heavy equipment such as a jackhammer.
