Initial Power Test 

1.  Before connecting to the VCA100, use a voltmeter at the VCA100 power harness 

connector to check for a constant +12VDC, switched +12VDC, and ground (Figure 3 
shows the VCA100 power connector). 

2.  Follow the steps as listed in Table 6.  Correct any problems encountered before 

proceeding to the next step. 

 

 

Required Equipment:  Volt/Ohm Meter 

1 

Verify VCA100 power harness is 
disconnected from VCA100 and energized 

VCA100 power harness 
disconnected and energized 

 

2 

Probe the VCA100 power harness connector 
Pin 1 for a constant +12 VDC 

Voltmeter reads vehicle power 
as approximately +12VDC 

 

3 

Set the VCA100 power switch to ON 

Power switch is ON 

 

4 

Probe the VCA100 power harness connector 
pin 2 for switched +12 VDC (sense) 

Voltmeter reads vehicle power 
as approximately +12VDC 

 

5 

Set the VCA100 power switch to OFF 

VCA100 is OFF 

 

6 

Probe the VCA100 power harness connector 
pin 2 for switched +12 VDC (sense) 

Voltmeter reads 0 VDC 

 

7 

Probe VCA100 power harness connector pin 
4 (ground) to chassis ground with ohmmeter 

Good ground connection exists 

 

8 

Connect VCA100 power harness to VCA100. 

Items are connected. 

 

9 

Turn on VCA100 unit and monitor Activity 
LED. 

Activity LED lights up during 
boot up.
