6.2. Connection description
Connect the twisted pair of wires in harness to the OBDII diagnostic connector according to the table above, ie.
orange-brown wire to the OBDII connector pin No. 14 and the orange-black wire to pin 6 of the OBDII connector. The
OBDII connector itself must remain free for connection of diagnostic tools.
On the OBDII connector there is also a permanent on-board voltage ("KL30") on contact 16 and a ground ("KL31")
on contact number 4. These can be used to power the unit. Therefore, the part of the standard unit connection can
be made directly on the OBDII connector.
In the vehicles, where the unit cannot be connected to the OBD connector for various reasons is possible to
connect the unit to another CAN bus or use DLC for older FORD vehicles. Such involvement should be consulted with
the manufacturer.

Checking and diagnostics of mobile unit
All mobile units manufactured by Princip are double checked before delivery to the customer. It is very unlikely
that new unit is malfunctional. Follow these instructions if the unit does not operate properly.
7.1. Check connections of basic signals
Ensure that the correct voltage values are present on the connector and that the wires are properly grounded.
All voltages are measured against the vehicle's ground point.
·
At least one of pins No. 3, 4 or 24 must be connected to the ground,
·
if the ignition is turned off, the on-board voltage must be presented on pin No. 1 only,
·
if the ignition is turned on, the on-board voltage must be presented on pin No. 1 and 12.
If the wiring is not correct, fix the wiring and check again. After that, plug the connector into the unit and verify
that the AMP connector is properly inserted in the socket and the lock is securely closed.
Note: If all the signals are correctly connected but the unit still does not indicate the activity by red LED, contact the
manufacturer.
7.2. Verifying basic functions with diagnostic LEDs
Diagnostic LEDs are used to verify the basic functions of the unit. Each of the three LEDs (green, orange, red) can
either light, blink or remain off. Meanings of the LED states are described in the table below. Follow this procedure:
·
Place the vehicle outside garage, so that GPS signals can be received from satellites.
·
Turn the ignition key on to activate the unit.
·
Check the three indication LEDs on the unit.
·
The status can change. The final status is reached in max. 2 minutes.
Each of the three LEDs (green, orange, red) can either be lit, flash or remain off. The status of each LED is
described in the table below.
The red LED can also blink for a few seconds after the ignition is switched off.
