A customer reached out to us, saying, “Hey, I recently received Autel MaxiIM IM608 Pro II and used it twice. However, now, when I try to connect it to the car via OBD, it won’t establish a connection. Any suggestions?”
Here is the solution:
1. Ensure that when you plug in your lead to the VCI, no pins have been bent. Based on your picture, PINS 4 and 5 are bent upwards, causing a lack of grounding.

2. Use a short OBD extension cable to protect your tool in the future.
Therefore, the Autel IM608 2 connection problem solution is to check the OBD plug. You may have bent pins, which could result in a lack of grounding. Additionally, use a short OBD extension cable for future protection.
