Mazda Back Up Light Switch

The Mazda Back Up Light Switch ensures bright illumination at the rear end, ensuring safety during parking or night driving. Mazda built its reputation on lively handling, KODO design language, and fuel-saving SKYACTIV engines that let the driver enjoy sports performance without burdening the owner with excessive fuel bills. In 1931, with the first three-wheeler truck to present-day crossovers, the company has been breaking conventions with lightweight engineering and bold ideas to keep the fans excited. The automobile combines the traditional gasoline powertrain with emerging hybrid and electric systems, allowing cleaner mobility while still being fun to drive. Safety features like i-ACTIVSENSE adaptive cruise and lane keep protect you and your passengers while making long journeys less tiresome. Available i-ACTIV all-wheel drive also shows confident grip on wet or off-road surfaces. Mazda launches many models in the market because the philosophy behind each Mazda model is to bring a car that connects drivers with driving, looks great, and has smart technology at the right price. This philosophy makes the Mazda badge equally popular among car lovers and everyday commuters. The Back Up Light Switch is part of a practical tech trend, completing the circuit from the battery to the rear-facing bulbs only when shifter or hydraulic pressure indicates reverse. This prevents wasted power and premature bulb burnout. Due to its compact size, it can be mounted on the transmission case, the console, or the steering column and will suit manual and automatic layouts across the range. By integrating with existing ring circuits, the Back Up Light Switch will work universally within Mazda vehicles. This allows every driver to help back out of tight spots with bright safety lighting.

You'll get great performance and real durability when you pick genuine OEM Back Up Light Switch. Mazda builds these using high-quality materials and official factory methods to ensure they hold up mile after mile. You deserve that Mazda reliability without the headache of cheap knockoffs. It is easy to find exactly what you need in our huge inventory of genuine parts. Plus, every OEM part carries a real manufacturer's warranty for your peace of mind. You will love our low prices too. Order today and we will ship your brand-new parts fast. They often reach your door in just a few days.

Mazda Back Up Light Switch Parts and Q&A

Back-Up Switch
F523-17-640B
Q:
How Is the Back Up Light Switch Tested, Diagnosed, and Replaced on Mazda Protege?
A:
The backup light switch is on the front side of the transaxle case, toward the bottom. You will need to turn the ignition key to the on position and move the shift lever to Reverse at this point. This should close the back-up light circuit. As a result of this closure, the back-up lights will come on. Check the back-up light fuse if the lights are not lighting up. Check fuse and switch battery voltage with ignition ON. If OK, the battery may be faulty; if not, the battery may still be OK. When there is no voltage present on the battery side, check the wire between the fuse and the switch; if it has voltage, put shifter in reverse and check for voltage on the ground side of the switch. If voltage is not present on the ground side, switch out the switch. If voltage is present, find out whether one or both of the back-up lights are out. If either bulb is open then replace the bulb but if both bulbs are open then maybe the bulb is faulty but more likely than not there is open wire between switch and bulbs. To change the switch, disconnect the electrical connector in the harness and then unscrew and take out the old switch. Now, check the new switch for continuity across the terminals-there should be continuity with the plunger pressed down and none with it free. First, install the new switch and tighten to the specified torque. Reconnect the electrical connector. Check the Switch to make sure the circuit is complete.
