Fast Blink Turn Signals... stumped

Postby dkneble » Wed Oct 18, 2017 12:21 pm

2004 Infinity FX35

Both sides demonstrate the fast-blink turn signal condition when used. Hazards work at normal speed. All bulbs work.

Have replaced all bulbs, the combination switch and the BCM. Dealership also checked out the tail lamp module.

Where do I go next? Or how to troubleshoot this?

Thanks.

Welcome to NICO Club!

I would have suspected the blinker control module, but there is also a separate rear combination control unit that may be acting up.

Are there any extra complications such as an aftermarket reverse camera installation? Do all four (six if on the mirrors) of your blinkers work when using your turn signal (front and rear left, then front and rear right)? Did replacing parts create this situation or was that in response to the fast blinking? What happened when the fast blinking started?

If no aftermarket changes, then the FSM is likely where to look for ideas (the dealership is probably using that and should have been able to fix it for you). Here's a link to all the chapters in your FSM: You can use the FWD and IDX chapters to find your way around.

There are no aftermarket items such as a backup camera. All four lights (none on mirrors) exhibit the same issue.

I purchased the car used and with this issue, hoping it was just a simple combination switch or bulb. So I do not know when the problem first started.

Dealership was stumped and basically at the point of starting to troubleshoot the harness.

Okay, well, the FSM is the way to go for diagnoses, so you're already on your way. Maybe someone will see this with personal experience and a post quick fix. I wonder if the blinker module can be mixed up with a similar part but with different speeds for flashing. Anyway, I hope you get it fixed up. Maybe see if there is an aftermarket blinker system associated with your car. I remember when we bought our Nissan Versa, they had snuck in an extra fee to have some sort of 'safety braking' system added to the car. It was supposed to flash the brake lights like three times whenever you stop. We were pissed that it was snuck in and had the charge removed and never installed the system, but it is some sort of Nissan Dealership thing and it messes with the lights so you could ask about that.
