Subject:
SVS "Wrench" Lamp Illuminated with DTC B1372 Set and DTCs U2105, U2106, and/or U2108 Also Set (Active or in History) (Reprogram BCM on

Models:
2004-2005 Saturn VUE Vehicles with 3.5L V-6 Engine VIN 4 - RPO L66)
Attention:
Fixed Operations Manager and Technician
Condition
For 2004 Saturn VUE vehicles built up to and including VIN 4S860922, some customers may comment that the Service Vehicle Soon (SVS) "wrench"
lamp is illuminated. Diagnostic trouble code (DTC) B1372 may be set. If DTC B1372 is stored in history with DTCs U2105, U2106, and/or U2108 also
set (active or in history), DTC B1372 may have been falsely set.
For 2004 Saturn VUE vehicles built after VIN 4S860922 and all 2005 Saturn VUE vehicles, the SVS lamp may not be illuminated, but DTC B1372 may
be stored in history. If DTC B1372 is stored in history with DTCs U2105, U2106, and/or U2108 also set (active or in history), DTC B1372 may have
been falsely set.
Cause
The 3.5L V-6 (L66)/5AT (MJ7/MJ8) powertrain control module (PCM) may not be communicating properly with the body control module (BCM).
Correction
Verify the condition and reprogram the BCM on any 2004 Saturn VUE vehicle built up to and including VIN 4S860922.
On 2004 Saturn VUE vehicles built after VIN 4S860922 and all 2005 Saturn VUE vehicles, verify the condition and clear DTC codes only
(reprogramming the BCM is not necessary). Do NOT replace the BCM, or any electrical components.
