Maintenance Tips of CHANGAN 3703020MK03 Battery sensor for CS85 Coupe/CS75 Plus/Uni-T/Uni-K
- First, ensure the vehicle's ignition is off before starting to work on the CHANGAN battery sensor (OE# 3703020MK03). This prevents electrical shocks and potential damage to the sensor.
- Use a multimeter to test the battery sensor's voltage output. For CHANGAN CS85 Coupe, CS75 Plus, Uni - T, and Uni - K models, the correct voltage reading indicates proper function.
- Clean the sensor's connectors thoroughly. Dirt and corrosion can disrupt the signal transmission of the battery sensor.
- Check the mounting bracket of the battery sensor. A loose bracket can cause inaccurate readings and premature sensor failure.
- Compare the new battery sensor (OE# 3703020MK03) with the old one to ensure correct fitment before installation.
Electrical Hazard Warning – The battery sensor deals with high - voltage electricity. Always disconnect the battery before installation and wear insulated gloves.
