Communication summary
バッテリーランプと DTC B1489 この情報は、Regulated Voltage Control（RVC）モジュール付きの 2005-06 Escalade、Avalanche、Suburban、Tahoe、Denali、Sierra、Denali、Yukon XL および 2005-07 Silverado と Sierra Classic に適用する。 車両でバッテリーランプが断続的に点灯し、Battery Generator Control Module（BGCM）に履歴コード B1489 が残っていることがある。 この不具合は、別の問題で BGCM を交換した後に気づかれることがある。 BGCM を交換したときは必ず、車両をユーザーに引き渡す前にモジュールを SPS でプログラミングする必要がある。 キャリブレーションが正しく完了していなかった場合や、モジュールがプログラミングされないまま車両が販売店を出た場合、DTC B1489 が入り、その後バッテリーランプが断続的に点灯することがある。 Machine translation (unreviewed)
