2011 Nissan Sentra Car Batteries Parts Questions & Experts Answers

• Q: What are the steps and precautions for disconnecting and reconnecting the 2011 Nissan Sentra's car batteries?

  A: It is recommended that you remove the black cable before the red one and connect the black one after the red one in order not to short the battery with the tool which was used in loosening the nuts of the cable clamps. There are components in a car where power is drawn from the battery to continue running a system or managing a control unit's memory; therefore, it is recommended to take out the key or keyless entry pad before disconnecting the battery to avoid the doors locking. Saver power device may also keep systems with power while disconnecting; usually, it connects to the cars' cigarette socket and another battery that could retain security codes of the audio unit as well as improved memory. To remove the power source, unscrew a nut on a cable end and pull it off the negative terminal, so it does not short circuit the vehicle. To reconnect, connect the positive terminal, followed by the negative. After reconnecting, there are a few re-learn procedures that have to be done: Steering angle sensor position learning, Idle Air Volume Learning, Power Window Initialization, Sunroof Memory and Radio Presets, if a Memory Saver was not used. The position learning on the steering angle sensor should be done by the qualified repair shop. As for idle air volume learning, it is necessary to check the battery voltage and the engine temperature before the corresponding procedures are conducted. The accelerator pedal released position and throttle valve closed position learning procedures contain ignition sequences and conditions that have to be fulfilled. Power window initialization is characterized by closing the window fully and using the switch to establish the position and the sunroof initialization calls for some procedure that test the functionality of the anti-pinch mechanisms.
