3.  Product Use

3.1  Test OBD-II port before plug in scantool

The OBD-II Smartbox performs tests on all 16 pins of the OBD-II 
port for abnormalities caused by shorting, reverse polarity, etc. 
in order to avoid damage to your scan tool prior to plugging in.

 

t

Test is carried out with ignition key in the OFF, ON and ENGINE 
RUNNING conditions.

3.1.1  Test without ignition key

1. 

Connect the OBD-II Smartbox to the OBD-II port on the vehicle.

2. 

The testing of the DLC port starts automatically as soon as 
the OBD-II Smartbox is plugged into it. 

 

t

This test is to check the condition of all pins before the ignition 
key is switched on.

Voltmeter LED

As soon as it powers up, the voltmeter will display voltage input. 
Notice the alarm beeps on teh following condition:

 

y

For 12V system:

 The alarm 'beep" will trigger ON (once at 

a time for 30 seconds) when the voltage falls below 11.8V

 

y

For  24V  system:

 The alarm 'beep" will trigger ON (twice 

at a time for 30 seconds) when the voltage falls below 23.8V

Fig. 1: 

Voltage alarm

When the battery falls below 11.8V for 12V system or 23.8V for 
24V system, the alarm will come on. In this case, you may need 
to start the engine to run for some time to charge the battery or 
replace with a new battery and then test again.
