# LOSS OF OWNER CUSTOMER SETTINGS

#### SUBJECT: LOSS OF OWNER CUSTOMIZATION SETTINGS (REPLACE BCM)

#### MODELS: 1997-98 CHEVROLET VENTURE 1997-98 OLDSMOBILE SILHOUETTE 1997-98 PONTIAC GRAND PRIX, TRANS SPORT WITH UA6 THEFT DETERRENT SYSTEM OPTION

#### CONDITION:

SOME OWNERS MAY COMMENT THAT THE CUSTOMIZED SETTINGS THEY PROGRAM ARE LOST A FEW DAYS (USUALLY ABOUT 3 DAYS) AFTER PROGRAMMING. THIS CONDITION OCCURS ONLY ON VEHICLES WITH THE UA6 THEFT DETERRENT SYSTEM. THE SETTING LOST IS USUALLY THE AUTOMATIC DOOR LOCK/UNLOCK FEATURE, BUT COULD BE ANY OTHER CUSTOMIZED SETTING CONTROLLED BY THE BODY CONTROL MODULE (BCM).

#### IMPORTANT:

THE OWNER'S MANUAL HAS ONE INCORRECT PIECE OF INFORMATION ON CUSTOMER PROGRAMMING. UNDER "LOCKS AND LIGHTING CHOICES" IN SECTION 2, THE TABLE SHOWS THAT IF 3 CHIMES ARE SOUNDED, THE "REMOTE LOCK/ UNLOCK CONFIRMATION" CAN BE SELECTED. THIS OPTION IS NOT AVAILABLE IN THE 3 CHIME MODE. THIS WAS CORRECTED IN THE LATE 1997 OWNER'S MANUAL PRINTINGS.

THIS IS A NORMAL CONDITION FOR THESE VEHICLES, AND PERFORMING THIS BULLETIN PROCEDURE WILL NOT CHANGE THAT CONDITION.

#### CAUSE:

A QUALITY CONCERN IN THE BCM ALLOWS THE CUSTOMIZED SETTINGS TO BE SELECTED, BUT THEN LOST. THIS OCCURRED ON BCM'S PRODUCED BETWEEN FEBRUARY AND AUGUST OF 1997. A NEW PART NUMBER HAS BEEN RELEASED TO CORRECT VEHICLES WITH THE ABOVE CONDITION.

#### CORRECTION:

REPLACE THE BCM WITH NEW PART NUMBER 10410079, FOLLOWING THE INSTRUCTIONS IN THE SERVICE MANUAL.

#### PARTS INFORMATION:

PARTS ARE CURRENTLY AVAILABLE FROM GMSPO.

#### WARRANTY INFORMATION:

FOR VEHICLES REPAIRED UNDER WARRANTY, USE:

LABOR OPERATION NUMBER: N4800 USE PUBLISHED LABOR OPERATION TIME.

FIGURES: 00 ATTACHMENTS: 00
