Autel MaxiCheck PRO [18/76] Vehicle coverage

3.7 Vehicle Coverage

On the basis of all OBD II compliant vehicles, including those

equipped with universal protocol -- Control Area Network (CAN),

MaxiCHECK Series Scanner expands vehicle system coverage and

offers more diagnostic power to the vehicle technicians. Featuring

expanded global vehicle coverage, the scan tool offers technicians a

significant improvement on model years covered by supported

manufactures. In addition to adding new vehicle coverage through

2010/2011, we’ve also worked backwards to include non-OBDII

vehicles, which can be diagnosed by setting up with optional OBDI

adaptors.

For a complete listing of all the added vehicle coverage, download a

3.8 Product Troubleshooting

Vehicle Linking Error

A communication error occurs if the scan tool fails to communicate

with the vehicle’s ECU (Engine Control Unit). You need to do the

following to check up:

 Verify that the ignition is ON.

 Check if the scan tool’s connector is securely

connected to the vehicle’s DLC.

 Turn the ignition off and wait for about 10 seconds. Turn the

ignition back to on and continue the testing.

 Verify the control module is not defective.

Operating Error

If the scan tool freezes, then an exception occurs or the vehicle’s

ECU (Engine Control Unit) is too slow to respond to requests. You

need to do the following to reset the tool:

 Reset the scan tool.

ignition back to on and continue the testing.
