TennaFLEET Tracker (JBUS) Installation

What: Tracker Installation is performed in the field using the Tenna App. This process covers the installation of the tracker to the asset, and the association of the tracker to an asset in Tenna. 

Refer to How to Associate a Tracker to an Asset to associate your tracker to an asset prior to beginning the installation process. 

Who: Mechanics, Equipment Managers, Users with permission to install trackers. 

Pre-Installation Prep

• Prior to beginning installation, be sure to manually enter the current miles shown on the vehicle's odometer. Make sure to enter the correct value as this will become the baseline for your vehicle's odometer calculation moving forward. 

Note: if you enter a value that is lower than the current mileage on the asset, you will receive an alert. 

• Make sure that your vehicle is outside with a clear view of the sky. If not, the tracker will take longer to set up properly, or installation may fail altogether.

Step 1.  Connect the tracker.

Ensure that your ignition is off and that your key has been removed from vehicle.

1. Identify the location of your vehicle’s JBUS port. This will generally be on the driver’s side below and to the left of the steering column, it could be behind the access door – the location of the port is dependent on the vehicle manufacturer.
2. You will then need an adapter cable for your JBUS fleet tracker. There are two different types of adapter cables, which will vary depending upon the year of your vehicle. -For vehicles that are 2005 and older: you will need a 6 pin J1708 cable, which is non-locking and black in color. -For vehicles that are 2006 and newer: you will need a 9 pin J1939 Type 2 cable, which is locking and green in color.
3. When you have the correct adapter cable, plug in your fleet tracker into the cable.
4. Line up your tracker with the JBUS port straight so that it can plug directly into the socket without any bending motions.
5. Press firmly to seat the tracker in the port. It is important to properly align the tracker and port to avoid damage to the pins and tracker. If you find insertion difficult, withdraw the tracker and examine the pins to ensure that they have not been bent or damaged.

There are four LEDs located on the side of the tracker opposite of the pins. Approximately two seconds after the tracker is inserted all four of the LEDs will flash one time in unison. This indicates that the tracker is receiving power from the vehicle.

1. Turn on the vehicle’s ignition.
2. Observe the Green LED. At ignition will glow solid indicating that the tracker is trying to communicate with the vehicle. Within five minutes the Green LED should flash once per second indicating communication with the vehicle’s Engine Control Unit (ECU) has been established.

The Amber LED will begin flashing. Once the tracker has established a GPS lock, the Amber LED will glow solid.

Note: This can take five minutes or more depending on location.

The Red LED will come on and flash intermittently while it is attempting to make a cellular network connection.

Once a connection has been established, the Red LED will illuminate for 2-3 seconds or during the entire time of status communication which could last up to ten seconds.

Step 5: Drive at least 2 miles.

In order to test proper communication of all data points, the vehicle must be driven for at least 2 miles on mapped roads. Simply driving around in your company parking lot may impact the quality of trip data

Once you return, park the vehicle outside and remove the key from the ignition.

It is important to keep in mind that a fellow employee will be verifying the data of this trip. As a result, discuss your route with your partner, as this will allow them to make an accurate assessment of your trip data.

Step 7. Observe all LEDs are off.

Make sure all LEDs on the Fleet Tracker go out.

Note: This can take 1-2 minutes to occur.

Step 8. Verify the tracker.

You have now completed the required steps to install your tracker. Verification of this tracker is a separate step that will be completed on Tenna Online.
