Can OBD-II be used to control the vehicle?

Yes, it is possible to control the car with OBDII port but it all depends on how the car was developed that you are using as there is no option to control the car using generic PIDs. You have to sniff the data and then find the correct command to control what you want to.

What can you do with OBD?

An OBD reader (also called a diagnostic scanner or scan tool) is a vehicle diagnostic device that can be used to read the error memory and data that is recorded on your vehicle systems. Basically, an OBD reader allows you to establish a connection between your car and a mobile app or diagnostic software.

Can you charge a car battery through the OBD port?

Connecting through the OBDII port is effective for battery charging even when the key is off, unlike charging through the cigarette adaptor which only works with the key in an ‘on’ position. The OBDII connector cord is 22 inches from the connection to the charger to the OBDII port and is fused for safety.

Does the OBD port have power when the car is off?

OBDII diagnostic port has +12 volts on pin 16, to fuse F20 under dash to fuselink 3 under hood to battery. So it would have power even when truck is off.

Can you leave OBD2 plugged in while driving?

It’s completely safe to leave an OBD2 scanner tool plugged in while driving. In fact, it’s important to have your car running while you diagnose an engine code to avoid damaging the scanning software.

Can OBD2 scanner damaged ECU?

Apart from some “killer commands”, the ECU might have been destroyed electrically. The OBDII-Interface can implement several different data buses with different voltage levels. If the bus lines get connected to +12V, this could destroy something.

What can OBD2 tell you?

An OBD2 scanner provides detailed records that can help. For example, you can use an OBD2 scanner to track vehicle health. OBD data like RPM and fuel efficiency can help you measure depreciation. You can also use an OBD2 scanner to monitor fleet vehicle depreciation.

What is the difference between OBD and OBD2?

OBD is the abbreviation for on-board diagnostics. OBD2 refers to the second generation of the onboard diagnostic system. OBD or onboard diagnostics is the system in a car that controls and monitors all the important control devices, offering data access with the appropriate hardware and software.

What is the difference between an OBD reader and scanner?

A code reader is a simplified version of a scan tool, but it’s only capable of performing basic scans of trouble codes. A scan tool can read and clear trouble codes, and it may also provide advanced data reading and playback features, knowledge bases, diagnostic procedures, and built-in testing equipment.

How accurate are OBD scanners?

Entirely accurate. These devices are not rocket science, and nor are they pocket mechanics. They simply report out the codes they extract from the car’s computers.
