8 Visually check the connection of pin 8 Both pins should be connected 11 & 12 These two pins are the power supply The pin. Attach the positive cable of voltage multimeter to pin 11 & 12 individually, across and attach the negative cable of two multimeter to the ground should be 3.3V. If it’s not, check the OBD-II port and car battery. 13 - 19 Attached the positive cable of The multimeter to the pin 13-19 current individually, and attach the negative should be cable to the other side of the wire around 100mA to 300mA 20-24 & Attached the positive cable of The 29-32 multimeter to the pin 20-24 & 29-32 current individually, attached the negative should be cable to the other side of the wire around 100mA - 300mA Table : Microcontroller testing criteria 10.1.8 Accelerometer # Test Expected Pin Result 1&3 Attach the The voltage positive should be cable of around 1.9V multimeter to 3.6V, if its to the pin not, the 1, and connection attach the between MCU
