Greetings to everyone,
My vehicle was in the shop for two months, and upon its return, I saw a "auxiliary battery malfunction" notification on the dashboard, leading me to consider that it may need charging or replacement. I assessed the battery's condition, and the voltmeter indicated a healthy charge of 12.6V. Additionally, I connected it to the charger, which displayed a Full Charge status. I connect the automobile to a charger, and it has provided
C073300, "Retrieve fault memory from control module."N10 (SAM Control Module) B1E211B The buffer battery is defective. The resistance limit has been surpassed.
I have wire brushed the connections, nevertheless the same issue persists.
Is the voltage measurement an inadequate indication of the battery's condition, or should I assess other components inside the vehicle?
Thank you very much
