Manufacturer summary

Original wording in English

Service Update. Certain vehicles may exhibit the high voltage bulkhead battery disconnect unit (BBDU) positive and/or negative contactors or relays, permanently or intermittently welded in the closed position. Contactors welded in the closed position will set DTC?s P0AA1 (positive), P0AA4 (negative), and P0C76 (hybrid). The malfunction indicator lamp (MIL) may also illuminate and vehicle may not start with this condition. Dealers will reprogram the hybrid powertrain control module.

Repeated filings are grouped only when make, bulletin number, publication date and complete summary agree. Original record numbers are retained. Older publications remain available, and an explicit later version is shown when established. Pre-1994 vehicle associations are separated from default results; an unspecified year does not mean all model years apply.
