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 2004 Vehicles, Clear DTC Codes on 2005 Vehicles)

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.

Service Procedure

  1. Verify that vehicle is a 2004 or 2005 Saturn VUE with 3.5L V-6 (L66) engine.
  2. Connect the Tech 2 scan tool to the vehicle and check diagnostic codes.
  3. • For 2004 vehicles built up to and including VIN 4S860922:
       - If DTC B1372 is stored in history with DTCs U2105, U2106, and/or U2108 also set (active or in history), proceed to step 3 to reprogram the BCM.
       - If DTC B1372 is stored in history and DTCs U2105, U2106, and/or U2108 are not set (active or in history), proceed with standard B1372 diagnostics. Refer to "DTC B1372" (SI Document ID# 1269114) in the Body Control System subsection of the Body section of the 2004 Saturn VUE Service Manual, Vol. 2.
    • For 2004 Saturn VUE vehicles built after VIN 4S860922 and all 2005 vehicles:
       - If DTC B1372 is stored in history with DTCs U2105, U2106, and/or U2108 also set (active or in history), clear the codes from the BCM. Reprogramming is NOT necessary for 2004 Saturn VUE vehicles built after VIN 4S860922 and any 2005 Saturn VUE vehicles.
       - If DTC B1372 is stored in history and DTCs U2105, U2106, and/or U2108 are not set (active or in history), proceed with standard B1372 diagnostics.
       - For 2004 Saturn VUE vehicles built after VIN 4S860922, refer to "DTC B1372" (SI Document ID# 1269114) in the Body Control System subsection of the Body section of the 2004 Saturn VUE Service Manual, Vol. 2.
       - For all 2005 Saturn VUE vehicles, refer to "DTC B1372" (SI Document ID# 1441763) in the Computer/Integrating Systems subsection of the Vehicle Control Systems section of the 2005 Saturn VUE Service Manual, Vol. 4.

    Important: Perform reprogramming procedure on 2004 Saturn VUE vehicles built up to and including VIN 4S860922 only , if needed per Step 2 in this bulletin.

    Important: Before installing new BCM calibration, make sure the Saturn Service Stall (SSS) version is TIS 8.0 2005 or later.

    Important: While ignition is OFF, apply parking brake to disable daytime running lights (DRLs) prior to starting reprogramming procedures.

  4. Reprogram the BCM with the latest available service calibration using the Saturn Service Stall system. Refer to "Body Control Module (BCM) Programming/RPO Configuration" (SI Document ID# 1201750) in the Body Control System subsection of the Body section of the 2004 Saturn VUE Service Manual, Vol. 2 for reprogramming procedures.
