How to Deal with Mazda 6 ROOM Electrical Leakage?
2 Answers
Turn off the ignition switch, all possible electrical devices, and all doors, then lock the car with the remote and wait for 5-10 minutes to let the vehicle enter sleep mode; Loosen the negative terminal screw and measure with a multimeter. It is recommended to go directly to a repair shop or a 4S store to check the wiring. If there is any leakage, repair it accordingly.
As someone who frequently tinkers with cars, when encountering a Mazda 6 power leakage issue, I use a multimeter to measure the battery current. Set the multimeter to the current measurement mode and connect it in series with the negative battery cable. After ignition, wait 20 minutes for the vehicle to enter sleep mode. Normal leakage current should be below 0.05 amps; anything higher indicates trouble. The most common causes are aging short circuits in the reading light switches or faults in the body control module. For DIY troubleshooting, start by checking the relevant fuses in the fuse box—pull them out one by one to observe current changes. Develop good parking habits: always turn off all interior lights and electronic devices before shutting off the engine. If you can't resolve it yourself, it's safest to have a professional shop inspect the wiring to prevent repeated battery drain and premature failure.
