Here is part of the operation:

1.Connect the tester to CAS4 computer; the machine will start self-test after it is powered up. 

2. If it tests CAS4, when it shows [recognize matched keys and CAS4 is connected], you can read data from CAS4-5M48H to match a key.

3. If the system identifies CAS4+, but shows [did not identify keys, you could try not to read data from CAS4-5M48H, as a new key cannot be matched now.
If you program a key now, the key can only be used for remote control but not start up vehicles. In order not to waste your time, keys, and risk, you’d better not try.

4. When matching new keys well, connect the tester and CAS4 computer, and then place the new keys in the inductive zone of the tester,
the system will inspect the keys automatically within 10 seconds, saving you from test it on your vehicle. This is suitable for long distance key matching.

At present, many friends fail to read data completely or damage CPU when matching CAS4-5M48H keys. With CAS4 Tester, you could avoid risk, and read complete data clearly.
It is a cost-effective and convenient tester to test CAS4 computer.
