Description:
X = 1: function enabled. Before using the function, you must ensure: 1. ACC detection is connected to input 1; 2. An
iButton key has been authorized.
X = 0: function disabled (default).
For example, after swiping the authorized iButton key, you must start the engine (input 1 is connected to engine
detection) within one minute. If the time exceeds one minute, you need to swipe the iButton key again. After the engine
is started, input 1 will always detect the ACC status. If ACC ON is detected (that is, input 1 is the high level), output 1
will not generate data. If ACC OFF is detected, wait for one minute and then swipe the authorized iButton key to start
the engine as required.
