Auto-Test Duration
The length of each Auto-test is measured in minutes. The default test
duration is 10 minutes. The test duration may be set between 10 and
120 minutes.
Manually enabling the Autotest feature
Switch SW5-8 is used to enable the autotest feature with a 14-day test
interval. The first autotest will begin 14 days from the time the ECM is
powered up with the configuration switch changed from 0 to 1 (OFF to
ON). To disable the autotest sequence, place switch SW5-8 in the OFF
position and restart the ECM. It is important to understand that upon
power up, the ECM looks for a change in the switch position before it
changes the test control parameters. (Please refer to ECM Manual, Alpha
