CAS Tester Functions

1. Checks whether the CAS program is running normally.
2. Verifies whether the CAS data is valid.
3. Detects whether the key is outputting an inductive signal.
4. Confirms whether the key is authorized and legal.

Tester Indicator Meanings

1. The D2 indicator flashes to show that the tester is communicating with the CAS module via CAN Bus.
2. The D4 indicator stays on to indicate that the CAS module data is valid.
3. Place the key on the induction coil; if the D3 indicator flashes, the key is outputting an LF signal.
4. A beep from the tester indicates that the key is valid for the corresponding CAS module or that a newly programmed key has been learned successfully.
