Hello

Many automotive systems today rely on software. Should that software develop errors, which can happen from something like a low battery, disconnecting the battery, or interrupting a learn procedure, it can cause all sorts of odd electrical problems that can be hard to troubleshoot. If you've got such a problem, try doing a battery cable reset; it just might do the trick. A battery cable reset forces all capacitors to discharge faster, and clears and resets most control unit volatile memory. It's like removing and reinstalling the battery in a cell phone that's acting weird or locking up. Before you start, make sure the battery is fully charged. A low battery can cause problems with electronics. Then, get the anti-theft code for the radio (if applicable). Now, follow these steps: 1.Turn/push the ignition switch to LOCK (0), and remove the key from the vehicle. This lessens the chance of voltage spikes. 2.Disconnect the battery cables-negative cable first, then positive. 3.Connect the positive and negative battery cables together. (make sure the cables are disconnected from the battery and they do not come in contact with the battery terminals) 4.Turn/push the ignition switch to ON (II), and wait 10 minutes. 5.Turn/push the ignition switch to LOCK (0), and remove the key from the vehicle. 6.Reconnect the battery cables to the battery. Positive cable first, then negative. If this reset doesn't work then you will need to connect a scan tool to the vehicle and check for trouble codes and also check the inputs/outputs of the modules and check for software errors.
