Will an obd2 Scanner drain battery?
So a poorly designed OBD device, when left plugged into the OBD port, might completely drain your battery. Worse still, if a device is not carefully designed, it can turn on your ECU even while the car is not running, draining your battery even faster.
Why is the OBD2 port pinout not communicating?
Thanx in advance. Here is is the OBD2 port pinout, a bad ground will prevent communication, pin 5 is a ground. See if it has a good ground. Key off and use a good 10 megaohm impedance ohmmeter to test the pin 5 to ground. If no ground the circuit is broken somewhere between the OBD2 connector and the PCM
Why is my OBD2 not getting power?
Check your fuses. Look for the one labeled “accessory”, “ACC”, “CIG”, etc. on the label on the fusebox lid. If you aren’t getting power at the port (easy to test with your multimeter), the fuse is likely the issue. If you ARE getting power, then options are: Break in the harness between the OBD2 connector and the ECU.
Why do I get No OBD code on my car?
Blown Fuse If you’ve plugged into your car’s diagnostic port and aren’t reading anything, you might think that your OBD-II brain has been fried, but don’t declare it dead yet. The most common reason for getting no OBD code is simply a blown fuse.
Is the OBD2 scanner not communicating with the vehicle?
OBD II Scanner refuses to communicate with the vehicle! the BCM will kill the obd2 port. probe off the diagram and I bet BCM controls the ground like it does on fog lights, windows, and gauges.
