What does code P0A7F mean?
The P0A7F engine code indicates a problem with your hybrid car’s high voltage (HV) battery pack, which is essential for powering the electric drive motors.
What is hybrid battery pack deterioration?
Hybrid Battery Pack Deterioration. DESCRIPTION. The battery smart unit and the hybrid vehicle control ECU calculate the SOC (state of charge) of the HV battery through the accumulated amperage in the HV battery. The battery smart unit sends the condition of the HV battery to the hybrid vehicle control ECU.
How do you test a Honda Civic hybrid battery?
To test the Honda Civic Hybrid battery, follow these steps:
- Shut the vehicle off.
- Disconnect the negative terminal for 10 seconds or more.
- Turn the vehicle on and let it charge.
- Watch the battery charge on the left side of the instrument cluster.
- The battery should charge up to eight bars, which means it’s full.
What is code P0AC4?
The P0AC4 error code would start indicating that hybrid powertrain control module has set an emission associated hybrid powertrain code. The hybrid powertrain control module would send a message via serial data circuit to the engine control module (ECM) requesting illumination of the Malfunction Indicator Light (MIL).
How do you recondition a hybrid battery?
NiMh Hybrid electric vehicle battery reconditioning consists of two primary elements: (1) charging/balancing the battery pack and (2) deep discharging the battery pack. Battery reconditioning is combining the charging/balancing process and deep discharging process multiple times to recondition the battery.
How do I fix code P0AC4?
How To Correct P0AC4 Hybrid Powertrain Control Module Requested MIL Illumination
- It is essential to restore the flawed hybrid powertrain control module.
- Repair or replace the quirky hybrid powertrain control module circuit.
- Rehabilitate the defaults in the ECM.
How much is a hybrid powertrain control module?
The average cost for a Powertrain Control Module Replacement is between $887 and $947 but can vary from car to car.
