Data List/Active Test
- CHECK DATA LIST WITH INTELLIGENT TESTER
HINT:
According to the DATA LIST displayed by the intelligent tester, you can read the value of the switch, sensor, actuator, etc. without parts removal. Reading the DATA LIST as the first step of troubleshooting is one way to shorten labor time.
