Troubleshooting ZCI Vehicle Wiring Harness 119250KIT Having Inconsistent Right Turn Signal Flashing

Question

Question:

I have wired the ZCI 119250KIT to my 2014 Audi allroad and have encountered a slight issue. After the install and programing great videos from your team All of the functions for the brake and taillights, work perfectly with the exception of the right turn signal. There seems to be an inconsistent delay in the flash when the right turn signal is activated, instead of a rhythmic flash. There is no issue with the left turn signal. Ive triple checked the connections, checked the ground. Could there be an issue with the unit itself or am I overlooking something? Thanks

I reached out to my contact at Tekonsha and there are a few things that could be causing the ZCI Circuit Protected Vehicle Wiring Harness w/ 4-Pole Flat Trailer Connector and Installation Kit # 119250KIT you installed on your 2014 Audi AllRoad to have an issue with the right turn signal flashing correctly.

On your vehicle there is a few different wires that have a signal when the turn signal is applied, but some of them use a different pulse width that is hard for the module to read correctly. I would see if there is another right turn signal wire that has power that you can move the sensor to, as that will likely fix the issue.

The other thing is to move the sensor from the right side to the left, and the apply the hazards on your vehicle to see if it is reading correctly. If this fixes the issue on the trailer, then finding the a different wire on the right turn signal of your vehicle will correct the issue.

If this does not fix the flashing issue, it is possible that there is an issue within the Module and will need to be replaced.

I included a video of the # 119250KIT for you to take a look at.

Same issue but in both sides with a 2018 Tesla model 3. It all seems to work except both signal lights are intermittent. Any ideas?

Upon further troubleshooting, I connected each signal sensor to the running lights and they worked fine. So it’s not the Tekonsha unit. Could it be the lights themselves (LED) or the signal from the car?

@TimG It should not be the signal from the lights, as the running lights are LED along with the Turn Signals. I'd double check that you're hooked up to the right wires for the turn signals. I installed a wiring harness on a Tesla a few weeks ago and there were three wires, one running light, one was turn signals. Also I found that if you do not have the light plugged in to the harness, the harness doesn't get power. Use a circuit tester to probe into the wire with the light connected to find the correct turn signal wire on each side.

Answer 1

There is no real difference between the two. The #119250KIT that we offer is the Tekonsha 119251 packaged with a circuit tester that makes it easier to identify which taillight harness wire carries which lighting function.
