If you encounter any type of electrical concern (e.g, dead battery, engine no start, DTC(s) stored...), interview the customer before proceeding with normal MGSS diagnosis by asking if any aftermarket devices have been installed. Aftermarket devices may be the cause of the electrical concern. Below are a few examples of unusual electrical concerns caused by aftermarket devices.
Examples:
1. Devices connected to the DLC-2 (battery discharge/DTC stored)
2. Cell phone charger/accessory in 12V socket (engine no start or unable to turn off)
3. GPS tracking device (engine no start/battery discharge)
4. Dash cam (DTC stored)
5. Non-certified USB cable (Apple Carplay�¢���¢/ Android Auto�¢���¢ will not connect)
6. Over-sized wheels/tires (incorrect GPS location)
