The fault code P1D09 is a diagnostic trouble code related to the hybrid battery pack.

The estimated repair time for this code is 1.0 hour.

The cost of fixing this code is influenced by the hourly rate charged by the auto repair shop, which is typically between $75 and $150 per hour. Other factors that may affect the cost include the severity of the issue, the type of repair needed, and the availability of replacement parts.

It is important to have this code diagnosed and fixed promptly to avoid further damage to the vehicle and ensure optimal performance.

The P1D09 fault code is related to the battery control processor in the battery condition monitor module. The controller area network (CAN) sends and receives signals tofrom the battery voltage cell voltage sensor through two signal lines (BATT-CAN_H and BATT-CAN_L).

If the processor does not receive signals via the BAT-CAN lines for a set time, a malfunction is detected and a DTC is stored.

The P1D09 code specifically indicates a malfunction in the EP-CAN A BUS-OFF of the Battery Condition Monitor Module.
