[SOLVED] U064A Code: How To Fix Lost Communication With Battery Sensor

The automobile fault code U064A indicates a problem with the Battery Pack Control Module (BPCM) in hybrid vehicles.

The most common symptom is the Engine Light ON or Service Engine Soon Warning Light. The cause of this fault code could be a faulty BPCM, an open or shorted BPCM harness, or a poor electrical connection in the BPCM circuit. The repair is of moderate difficulty and importance, with a repair time of 1.0.

To fix the issue, one should visually inspect the wiring harness and connectors, check for damaged components, and look for broken, bent, pushed out, or corroded connector’s pins. It is crucial to address this issue promptly to avoid further damage to the vehicle.

  • The automobile fault code u064a can be caused by a faulty Battery Pack Control Module (BPCM).
  • It can also be caused by an open or shorted Battery Pack Control Module (BPCM) harness.
  • Additionally, a poor electrical connection in the Battery Pack Control Module (BPCM) circuit can also trigger this fault code.

To fix the automobile fault code u064a, check the possible causes and inspect the related wiring harness and connectors for any damage or corrosion.

  • To fix the automobile fault code u064a, you need to check the possible causes listed above.
  • Visually inspect the related wiring harness and connectors.
  • Look for damaged components and check for broken, bent, pushed out, or corroded connector’s pins.
  • Ensure that all the connections are secure and free from corrosion.
  • This repair process takes an estimated time of 1.0 hour.

The factors that influence the cost of fixing the automobile fault code u064a are the estimated repair time and the hourly rate charged by the auto repair shop. The estimated repair time for this fault code is 1.0 hour.

The hourly rate charged by most auto repair shops ranges between $75 and $150 per hour. These factors are crucial in determining the overall cost of fixing the automobile fault code u064a.

The U064A fault code indicates a communication loss with the HybridEV Battery Pack Current Sensor ‘A’. The Battery Pack Control Module (BPCM) manages battery voltage and maintains the 12-volt battery system.

The BPCM communicates with the vehicle via CAN-C bus and monitors other vehicle systems for fault detection reporting. The Diagnostic Trouble Code (DTC) sets when the BPCM detects a fault with internal or external components or circuitry. The Cell Supervision Circuits (CSCs) monitor and balance the battery cells, and they are located within the Battery Pack.

The BPCM provides battery management and system functionality in conjunction with the CSCs.

What are the possible causes of the u064a automobile fault code?

If you see the engine light on or the service engine soon warning light, it could be due to the u064a fault code. This code is usually caused by a faulty Battery Pack Control Module (BPCM), an open or shorted BPCM harness, or a poor electrical connection in the BPCM circuit. To fix this issue, you should visually inspect the wiring harness and connectors, check for damaged components, and look for broken, bent, pushed out, or corroded connector’s pins.

How can I visually inspect the related wiring harness and connectors to fix the u064a fault code?

If you’re experiencing the u064a fault code with the engine light on, it could be due to a faulty Battery Pack Control Module (BPCM), an open or shorted BPCM harness, or a poor electrical connection in the BPCM circuit. To fix this issue, start by visually inspecting the related wiring harness and connectors. Check for any damaged components and look for broken, bent, pushed out, or corroded connector pins. This will help you identify any issues and determine the best course of action to resolve the problem.
