DTC P06B1 (Battery Condition Monitor Module)
DTC P06B1: HV Battery Current Sensor Power Supply Circuit Low
General Description
The battery condition monitor module applies 5 V to the battery current sensor and monitors the voltage. When the battery current sensor voltage is a specified voltage for a set time, a malfunction is detected and a DTC is stored.
Monitor Execution, Sequence, Duration, DTC Type
| Execution | Continuous |
| Sequence | None |
| Duration | 2.0 seconds or more |
| DTC Type | Two drive cycles, MIL on, POWER SYSTEM indicator on |
Enable Conditions
| Condition | Minimum | Maximum |
|---|---|---|
| Elapsed time since the 12 volt battery voltage reaches to a specified value after the vehicle condition is turned to the ON mode | 50 milliseconds | - |
| 12 volt battery voltage | 7.7 V | - |
Malfunction Threshold
The battery current sensor voltage is 4.75 V or less for at least 2.0 seconds.
Possible Cause
NOTE: The causes shown may not be a complete list of all potential problems, and it is possible that there may be other causes.
- Battery current sensor VCCISOC line short to ground
- Battery current sensor failure
- Battery condition monitor module internal circuit failure
Diagnosis Details
Conditions for setting the DTC
When a malfunction is detected during the first drive cycle, a Pending DTC is stored in the battery condition monitor module memory. If the malfunction returns in the next (second) drive cycle, the MIL comes on and a Confirmed DTC and the freeze data are stored.
Conditions for clearing the DTC
The MIL is cleared if the malfunction does not return in three consecutive trips in which the diagnostic runs. The MIL, the Pending DTC, the Confirmed DTC, and the freeze data can be cleared with the scan tool Clear command.
