Subject: | Equipped with Trap Alert, Intermittent Horn Honk or Trunk Opens |

When servicing the vehicle with the VIN you entered, the following diagnosis might be helpful if the vehicle exhibits the described symptoms.
If the customer complaint is that intermittently the horn honks and the deck lid opens without motion detected in the trunk (which is normally necessary to activate the system), a malfunctioning sensor may be at fault; this may or may not set DTCs. Sensors are not available through GMSPO. Vehicles with a malfunctioning sensor must have the system disabled, see step 4 below. Refer to bulletin 01-08-66-004 for more information on how Trap Alert works. Reminder: Trap Alert as an option has been discontinued and sensors are not available.
There are three scenarios that might cause this condition. Check to see if the Trap Alert sensor in the trunk is enabled in the BCM(using personalization, set options).
The option of Trap Alert can be turned on in the BCM at any time but never turned off. Once Trap Alert is enabled BCM replacement is necessary to once again delete the option.

Please follow this diagnosis process thoroughly and complete each step. If the condition exhibited is resolved without completing every step, the remaining steps do not need to be performed. If these steps do not resolve the condition, please contact GM TAC for further diagnostic assistance. This diagnostic approach was developed for the vehicle with the VIN you entered and should not be automatically be used for other vehicles with similar symptoms.
