Advanced Diagnostics - DTC P0607 (82): Battery Condition Monitor (BCM) Module Performance Problem






General Description
The battery condition monitor (BCM) module detects the cell voltage of the battery module. The cell voltage is converted to voltage information in the high voltage processor through the battery scan circuit. The battery control processor obtains the cell voltage information through internal communication. When normal information is not sent from the high voltage processor for a set time, or when abnormal information is included in the information sent from the high voltage processor, and this condition continues for a set time, the battery control processor detects a malfunction and stores a DTC.
