DTC P0A80: Replace HV Battery Pack

General Description

Courtesy of HONDA, U.S.A., INC.

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 on, POWER SYSTEM indicator on, 12 VOLT CHARGING SYSTEM indicator on

Enable Conditions

Condition	Minimum	Maximum
12 volt battery voltage	8.0 V	-
Other	During initial start-up of the battery condition monitor module, after disconnecting the 12 volt battery

Malfunction Threshold

One of these 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.
The average voltage of resistance voltage acquired for 19 times is 2.61 V or less, or 3.84 V or more.

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, the MIL comes on and a Pending DTC, a Confirmed DTC, and the freeze data are stored in the battery condition monitor module memory.

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.
