Code P1DC7 Honda Description

Cell resistance deterioration factor in the discharged state is calculated based on the individual cell voltage from the battery module and the differentiated current and voltage when inputting and outputting electric power from the battery current sensor and the battery condition monitor module. If the cell resistance deterioration factor exceeds a specified value for a specified duration, the battery condition monitor module detects a malfunction and stores a DTC.
