Supersedes Technical Service Bulletin Group 57 number 09-24 dated October 28, 2009 for reasons listed below.
Affected Vehicles
Condition
One of the following conditions is present:
^ All vehicle keys do not lock or unlock the vehicle electronically.
^ One vehicle key intermittently does not lock or unlock the vehicle electronically. If one key is intermittently inoperative electronically, access/start
authorization control module J518 (address word 05) will store a DTC for "no or incorrect basic settings" for the key.
In both situations all keys still function properly mechanically, operating the door locks and ignition switch.
Technical Background
^ Convenience system control module J393 (address word 46) does not detect radio signals from the keys.
^ The remote key loses synchronization, for example by repetitive button presses while the remote is outside of the range of the vehicle.
Production Solution
Optimized Convenience system control module (J393) software.
