2. Bring other end of cable and tester into driver's compartment, leaving tester disconnected.
3. Set Emergency Brake.
4. Turn Vehicle Engine ON and let idle.
5. ONLY AFTER engine is running, plug the 9-pin connector to the socket of the tester and lightly tighten the
thumb screws.
6. Verify 12V circuit is powered, or turn on Tail/Tag Circuit.
7. Wait for yellow ECU detection light to stop blinking.
8. For vehicles equipped with integrated controllers, look for the words "Trailer Connected" on your instrument
panel and the ECU Detection light to remain steady, within a few seconds of connecting the #ET9107 to a
vehicle with engine running.
9. Set-up is now complete.
ALTERNATIVE SET-UP PROCEDURE
In late 2016 and 2017 models, some OEMs changed the way the brake controllers search for a trailer signal.
To establish a "Trailer Connected" message with these vehicles if the basic method described above does not
work, press and hold the brake pedal during #7 of the Set-Up Procedure.
PRETEST SET-UP (MUST FOLLOW EACH USE!)
NOTICE: Brake Force Meter w/ Dynamic Load Simulation and Circuit Testing will not function unless Tail/Tag or 12V
Aux Circuits have constant power. If your vehicle does not supply 12V Aux at the trailer connector, leave parking
lights on while testing.
WARNING: SET-UP MUST BE COMPLETE BEFORE ATTACHING CABLE.
WARNING: WHEN TESTING IN CAB, DO NOT PINCH CABLE IN WINDOW OR DOOR.
