Diagnostic Aids
WARNING: This page is about a different car, the 2004 Cadillac DeVille. However, it is still accessible from the selected car via links, so may be relevant.
IMPORTANT:
If DTC B2463 or B2465 is also set with DTC B2464, service B2463 and B2465 before DTC B2464.
Make sure the map DVD is the correct one for this system.
Cycle the ignition switch even after a successful inspection with a scan tool so initialization will occur.
