DTC P1DCB
DTC P1DCB: HV Battery Identification Circuit (System Running)
General Description
The battery pack built in resistance for battery module identifications are used for the battery condition monitor module to monitor whether an appropriate battery module is connected. If the battery pack resistance voltage for battery module identifications are out of specified value for a set time, the battery condition monitor module detects a malfunction and stores a DTC.
Monitor Execution, Sequence, Duration, DTC Type
| Execution | Continuous |
| Sequence | None |
| Duration | 2.0 seconds or more |
| DTC Type | One drive cycle, MIL off, POWER SYSTEM indicator on, 12 VOLT CHARGING SYSTEM indicator off |
Enable Conditions
| Condition | Minimum | Maximum |
|---|---|---|
| 12 volt battery voltage | 8.0 V | - |
| Other | After the electric powertrain system operated | |
Malfunction Threshold
One of the conditions is met:
- The resistance voltage is 4.98 V or more for at least 2.0 seconds.
- The resistance voltage is 0.03 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 pack MODID1 line open
- Battery pack MODID1 line short to ground
- Battery pack MODID2 line open
- Battery pack MODID2 line short to ground
- Battery pack internal circuit failure
- Battery condition monitor module internal circuit failure
Diagnosis Details
Conditions for setting the DTC
When a malfunction is detected, a Pending DTC, a Confirmed DTC, and the freeze data are stored in the battery condition monitor module memory. The MIL does not come on.
Conditions for clearing the DTC
The Pending DTC, the Confirmed DTC, and the freeze data can be cleared with the scan tool clear command.
