DTC P06B1 (79) (Battery Condition Monitor Module B)
DTC P06B1 (79): HV Battery Pack Current Sensor Power Supply B Circuit Low
General Description
The battery condition monitor module B applies 5 V to the battery current sensor B and monitors the voltage. When the battery current sensor B 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 seconds or more |
| DTC Type | One drive cycle, MIL on, POWER SYSTEM indicator on, 12 volt battery charging system indicator off |
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 B voltage is 4.8 V or less for at least 2 seconds.
Possible Cause
- Battery current sensor B B-VCCISOC line short to ground
- Battery current sensor B failure
- Battery condition monitor module B failure
Diagnosis Details
Conditions for setting the DTC
When a malfunction is detected, the MIL and the POWER SYSTEM indicator comes on and a Pending DTC, a Confirmed DTC, and the freeze data are stored in the battery condition monitor module B memory.
Conditions for clearing the DTC
The MIL and the POWER SYSTEM indicator are cleared if the malfunction does not return in three consecutive trips in which the diagnostic runs. The MIL and the POWER SYSTEM indicator, the Pending DTC, the Confirmed DTC, and the freeze data can be cleared with the scan tool Clear command or by disconnecting the 12 volt battery.
