NO: 59-15

DATE: 8-21-2007

MODEL: XC90 with V8 engines (engine code 85)

M. YEAR: 2005-2007

SUBJECT:
DTC BCM C008249, Software Available

VIDA

Description

There may be cases where DTC (Diagnostic Trouble Code) BCM (Brake Control Module) C008249 has been stored.

There also may be cases where DTC CEM (Central Electric Module) 1A5F is stored together with DTC BCM C008249. The CEM DTC is a secondary code which is stored when the BCM goes into CAN bus off mode if BCM C008249 is set. This means that the BCM is taken out of the CAN (Controller Area Network) mode until the next drive cycle.

Note!
If the BCM goes into CAN bus off mode, other electrical components dependent on signals from the BCM may store DTC's, for example CEM, TCM (Transmission Control Module), DEM (Differential Electronic Module) and ECM (Engine Control Module).

Service

If the symptom occurs perform BCM upgrade P/N 30677015. Do not replace the BCM. If the BCM upgrade does not solve the issue, then proceed with normal fault tracing in VIDA.
