SYMPTOM/CONDITION:
The service flash corrects the following conditions:

^ No start, or drained battery, due to the BCM keeping the vehicle communication bus awake.

^ Diagnostic Trouble Codes: B1606-95, B16AF-15, B16B3-15, B1632-15, and B1636-15

^ Trunk Lamps turn off after 30 seconds on the first time out delay after the ignition is cycled to OFF (A reduced time out delay after the first time out is normal behavior. The ignition must be cycled before a full ten minute delay may be observed again).

^ Passive Entry response time seems slow. User will typically complain of having to pull the handle twice to get it to work.

^ The trunk release button does not work while the doors are locked.

NOTE:
This software also includes behavior modification to police vehicle only wig wag behavior.

DIAGNOSIS:
Verify that the Body Control Module is functioning as designed. If DTC's other then those listed are present, record them on the repair order and repair as necessary before proceeding further.

If a customer's VIN is listed in VIP or your RRT VIN list, perform the repair. For all other customers that describe the symptom/condition or if the technician finds the DTC, perform the Repair Procedure.
