The FIXD OBD2 module does not drain your car battery. However, it can trigger other electrical circuits within the automobile. This may lead to parasitic draw, which can cause battery issues. To maintain car battery health, regularly check for these draws and any circuit problems to keep your battery functioning well.
While FIXD will not isolate battery drains on its own, it can point out related problems. For example, if a warning code relates to the electrical system, this may indicate a larger issue contributing to battery drain. Additionally, FIXD can provide insights into the health of the battery and alternator, which play crucial roles in battery performance.
To properly test for parasitic draw, you will need a multimeter. A technician can use this tool to measure the current flowing from the battery when the vehicle is off. This step will reveal if there is an excessive current draw, helping to troubleshoot battery drain issues more effectively. In the following section, we’ll discuss how to accurately test for parasitic draw using a multimeter.
