FAQ:

Q1: Is the software updated regularly? Are updates free?    
A: Yes. CR Max P includes lifetime free Wi-Fi software upgrades. No annual subscription required.  

 

Q2: What's the difference between CR Max P and the CR MAX BT?    
A: CR Max P is the update version of CR MAX BT.

Hardware upgrade: CR Max P features upgraded hardware (10-inch touchscreen, Android OS, Quad-Core processor, 64GB storage, 10000mAh battery).

Protocol upgrade: CR Max P standard equipped with RJ45 Network Cable, F-Chassis and USB2.0 to 10/100MNetwork Cable for DoIP protocol.

More advanced functions will be added to CR Max P.

 

Q3: The CR Max P cannot recognize my vehicle by AutoVIN, does it mean the device is faulty?
A: Not necessarily. Send your VIN to our support team and we'll confirm AutoVIN compatibility within 24 hours. In the meantime, you can manually select your vehicle model — all diagnostic functions will still work normally. We'll add your VIN to our database in the next update.

 

Q4: DTCs can be read normally but fail to be cleared or reappear after clearance, why?
A: Please keep ignition on and engine off. Record freeze frame data first before clearing codes.

Persistent hardware faults need physical repair prior to code clearance.

Some fault codes of systems like SRS and ABS can only be cleared after finishing bidirectional tests.

 

Q5: How to pair Bluetooth VCI?

A:

Step 1. Insert the VCI into vehicle OBD port, turn ignition to ON position.

Step 2. Enable Bluetooth on tablet, search and connect "CR Max P VCI".

Step 3. Green VCI icon means successful pairing.

Step 4. Select Bluetooth connection to start diagnosis.

FAQ:

Q1: Is the software updated regularly? Are updates free?    
A: Yes. CR Pro+ includes lifetime free software upgrades. No annual subscription required.  

Q2: What's the difference between CR Pro+ and the CR Pro?
A: Larger Screen: The upgraded CR Pro+ features a larger, clearer 4.3-inch display, whereas the older CR Pro comes with a smaller 4-inch screen.

More Service Functions: The CR Pro+ heavily expands your maintenance capabilities by supporting a much broader range of service reset functions compared to the foundational list on the standard CR Pro.

 

Q3: The CR Pro+ cannot recognize my vehicle by AutoVIN, does it mean the device is faulty?
A: Not necessarily. Send your VIN to our support team and we'll confirm AutoVIN compatibility within 24 hours. In the meantime, you can manually select your vehicle model — all diagnostic functions will still work normally. We'll add your VIN to our database in the next update.

 
Q4: DTCs can be read normally but fail to be cleared or reappear after clearance, why?
A: Please keep ignition on and engine off. Record freeze frame data first before clearing codes.

Persistent hardware faults need physical repair prior to code clearance.

Some fault codes of systems like SRS and ABS can only be cleared after finishing bi-directional tests.
