Maintaining the battery health of your Mitsubishi Outlander PHEV is crucial for optimal performance and longevity. One key aspect of this maintenance is ensuring accurate battery capacity readings. Over time, the estimated battery capacity in your PHEV can become inaccurate, potentially affecting range and charging efficiency. Fortunately, with a Think Car Obd Scanner, you can easily reset these estimations and ensure your vehicle operates at its best. This guide will walk you through the process of resetting your Mitsubishi Outlander PHEV battery capacity using a Thinkcar OBD scanner, providing a more detailed and SEO-optimized approach than previously available.
Before you begin this procedure, it’s essential to have your PHEV’s drive battery as depleted as possible. Ideally, aim for the battery level indicator on your dashboard to show just a single bar. Alternatively, if you use a monitoring app like PhevWatchdog, ensure the state of charge is very low. Driving until the internal combustion engine (ICE) consistently engages is a practical way to deplete the battery. If you need to expedite the process, you can run the air conditioning or heater with the windows open to draw down the battery charge more quickly. Once the battery is sufficiently low, park your car near a charger, as it will need to be stationary for several hours. The battery capacity reset process can vary in duration, with initial procedures suggesting up to 12 hours, while newer guidelines indicate it might take up to 72 hours. The actual time depends on factors like ambient temperature and whether your Outlander PHEV is equipped with a battery heater.
Do not connect the charger at this stage. First, plug your Thinkcar OBD scanner into the OBD-II port of your Mitsubishi Outlander PHEV. Then, switch your car to ‘Ready’ mode. If you have any charging timers set, disable them to prevent any interference with the reset procedure.
Now, access the diagnostic functions using your Thinkcar OBD scanner’s application on your Android device. Navigate to and select the “ALL SYSTEMS DIAGNOSTIC” option.
Initiate the vehicle identification process by clicking on “VIN Decoding.” Allow the Thinkcar app to automatically identify your car model. If prompted, download the specific Mitsubishi software package required for your vehicle.
Once the VIN decoding is complete, proceed to the “System Selection” menu. From there, choose “BMU” (Battery Management Unit), followed by “Special Function,” and then select “Battery Maintenance Function.” The BMU is the control module responsible for managing your PHEV’s battery system, and these special functions allow for advanced diagnostic and maintenance procedures.
Within the “Battery Maintenance Function” menu, locate and select “BATT. Capa. Estimated Info. Reset.” Confirm your selection to initiate the reset of the battery capacity estimation. After this, select “Control Information Reset” and confirm this action as well. These reset commands are crucial for clearing any learned data that might be causing inaccurate battery capacity readings.
In some cases, like the original author experienced, the ICE might start immediately after performing these resets. If this happens, simply turn off the car and then turn it back on in ACC (Accessory) mode.
Return to the BMU screen and this time select “Read Data Stream.” From the data stream options, choose “Battery Current Capacity” and confirm. After selecting this, the Thinkcar OBD scanner should now display the original, factory-specified battery capacity of your Mitsubishi Outlander PHEV (e.g., 38Ah in the example). If you still see the old, potentially inaccurate capacity value, repeat the reset procedure until the original capacity is displayed. For verification, you can also observe the “Battery Remaining Capacity” in the data stream, which indicates the current state of charge of the battery.
Once you have confirmed that the battery capacity has reset to the original value, turn off your Mitsubishi Outlander PHEV completely. Now, connect your charger to begin recharging the battery. You should observe the charging indicator illuminate on your dashboard, confirming that charging has commenced.
Finally, navigate back to the “BMU” menu, then “Special Function,” and select “Battery Auto Capacity Measured.” Initially, the “Execution Status” should display “Not Run” (or “Complete” if a Battery Auto Capacity Measurement has been performed previously). Click on the “Perform” button and confirm your selection. You should hear the vehicle’s AC compressor and cooling fans engage, indicating that the battery auto capacity measurement process is underway. The “Execution Status” should change to “Executing,” and “Capa. Measured Discharge Current” should display “Ok,” confirming the process is running correctly.
By following these steps with your think car obd scanner, you can effectively reset and recalibrate your Mitsubishi Outlander PHEV’s battery capacity estimation. This procedure helps ensure accurate readings, contributing to better battery management and overall vehicle performance. Regular battery maintenance using tools like the Thinkcar OBD scanner is a proactive step towards maximizing the lifespan and efficiency of your PHEV.
