Installation Guide (Standard)

LoJack ATS100 LTE

GPS Device

Installation Options:

1. 

The standard installation simply hard-wires to the vehicle. ATS100 supports both 2-wire and OBD passthrough 

install methods.

Standard Installation Instructions:

1. 

Using a digital voltmeter, locate a constant 12V source (meter 

should read 12V with the vehicle’s ignition in the off position) and 

a solid chassis ground location.

2. 

For installations without the OBDii pass through cable, cut off the 

quick disconnect on the device harness and connect the red wire 

to your constant 12V source and the black wire to ground.

3. 

Find a mounting location for the ATS100 LTE that is clear of 

metallic obstructions from above that could cause interference 

with GPS signal reception. Be sure that the ATS100 LTE is 

mounted in a manner that positions the printed ‘This Side Down’ 

indicator toward the floor of the vehicle. 

IMPORTANT: Take special 

care to secure the device to a solid surface using zip ties. In order 

for the accelerometer to work properly, the device must be firmly 

attached to the vehicle.

4. 

The ATS100 will only wake up with movement. The device will 

need to be awoken with movement before validation of the install.  

It will go back to sleep mode after 10 minutes if no additional 

motion is detected.

5. 

On initial power up, the LED indicators should show a flashing 

green LED and a flashing red LED while scanning for cellular and 

GPS signals, respectively. When the green and red LEDs stop 

flashing and remain solid, adequate cellular and signals have 

been acquired.

LED Indicators

Important: 

It may take five to seven seconds to see 

any LED activity and up to 10 minutes to 

get an initial GPS lock.

Caution: 

If, after 15 minutes, you are still unable 

to get GPS and / or cellular signals, 

reposition and try again.

LED Troubleshooting

Slow Flash = From powerup, 

system initialization

Fast Flash = GPS Lost / Cellular Data 

Connection Lost

Solid = Signal Acquired

Red LED Blips once every 30s = 

Device in monitoring or standby 

mode

Green LED fast flash = Cellular data 

connection is lost temporarily

Green = Cellular Signal

Red = GPS Signal
