Key Functions and How the Manual Guides You
The Autel MaxiScan MS300 is designed for several key diagnostic functions. The manual is instrumental in guiding you through each of these:
Reading Diagnostic Trouble Codes (DTCs)
The primary function of the MS300 is to read DTCs, which are codes stored in your vehicle’s computer system when a problem is detected. The manual will explain:
- How to initiate a scan to retrieve these codes.
- Where the codes are displayed on the device screen.
- Basic interpretation of the code format.
- Guidance on using the built-in DTC lookup function (if applicable, though MS300 often displays code descriptions directly).
Clearing Trouble Codes and Check Engine Light
Once you’ve addressed the issue causing the DTC, you’ll want to clear the codes and turn off the Check Engine Light. The manual will detail:
- The process to erase DTCs using the MS300.
- Important considerations before clearing codes (e.g., noting them down first).

I/M Readiness Status
The I/M Readiness feature checks the status of emission-related systems in your vehicle, crucial for emissions testing. The manual explains:
- What I/M Readiness monitors are and their importance.
- How to access the I/M Readiness status using the MS300.

OBD2 Protocol and Compatibility
The manual usually includes information about OBD2 protocols supported by the MS300, which is critical for ensuring compatibility with your vehicle. It will generally state that the MS300 supports all OBD2 protocols, including CAN (Controller Area Network), which is a standard in most modern vehicles. This is why “CAN OBD2 manual” is a relevant search term for users of this device.
