What causes the P0A6A code?

Potential causes of this fault code include:

• Faulty power inverter that is not delivering the correct voltage to Motor B.
• Worn or damaged electrical connections leading to inadequate power supply.
• A defective Drive Motor 'B' which is unable to generate the necessary current.
• Issues with the vehicle's control module that monitors and manages motor functions.

How to fix P0A6A?

To resolve the P0A6A fault code, the following steps may be taken:

• Perform a thorough inspection of the power inverter and associated electrical components for signs of wear or damage.
• Check all connections for corrosion or loose wires, tightening or replacing as necessary.
• Use a diagnostic tool to assess the Drive Motor 'B' for any faults and replace if found defective.
• Update or reprogram the vehicle's control module if errors are detected in the software.
