Overview
The 12V battery is charged by the Direct Current/Direct Current (DC/DC) converter control module. For more information, Refer to: DIRECT CURRENT/DIRECT CURRENT (DC/DC) CONVERTER CONTROL MODULE - SYSTEM OPERATION AND COMPONENT DESCRIPTION .
Scheme 25
Normal Operation and Fault Conditions
The BCM monitors the battery state of charge using the battery monitoring sensor attached to the negative battery cable. Battery voltage is hardwired to the battery monitoring sensor and data is transferred from the battery monitoring sensor to the BCM via a LIN circuit. The battery monitoring sensor is part of the negative battery cable and is not serviced separately.
| DTC | Description | Fault Trigger Conditions |
|---|---|---|
| B11DB:83 | Battery Monitoring Module "A": Value of Signal Protection Calculation Incorrect | This DTC sets if the BCM receives corrupted data from the battery monitoring sensor over the LIN . |
| B11DB:96 | Battery Monitoring Module hardware fault | This DTC sets if the BCM receives corrupted data from the battery monitoring sensor over the LIN . |
| U1007:00 | Lost communication with Battery Monitoring Sensor "A": No Sub Type Information | This DTC sets if the BCM does not receive an expected message from the Battery monitoring sensor. |
