As I posted in another thread, my turn signals have gone wonky. I am thinking I want to try re-marrying my cluster to the bike since it controls the turn signals. What is the correct procedure? Do I just disconnect it and reconnect it? Do I have to wait a period of time? Any confirmation the marriage is successful?

Start over, disconnect the negative battery cable, unplug the ECM, plug it back in. Connect negative battery cable. Turn ignition key on, and the reset the TPS.

The cluster will display a timer starting at 30 min and will count down, this is with a new cluster installed. The key needs to be on for it to count down so a battery charger will need to be connected to keep the voltage up. When the count down is complete the procedure is done.

Avc, the cluster can only be married once. If you would like to "soft reset" the cluster just disconnect your negative battery cable for a minute and reconnect.

Can you give a better description as to "my turn signals have gone wonky"?

The cluster does control the turn signals, but the ECM has nothing to do with that control.

As a side note, when you disconnect the negative terminal of the battery, you will lose your trip mileage and clock.

That is the thread I started with the turn signals.

The left signals work normally. The right signals (both) do not flash, but the IC turn signal light does.

I went through the fault tree in the electrical diagnostic manual, it says bad IC.

Two things I would double check that I have seen to cause this issue.

1. The cluster connector isn't properly seated.

2. The pins going into the cluster connector from the cluster are bent.

I would start by disconnecting the cluster connector. Then look at the pin on the cluster to make sure none are bent. If everything looks kosher, reconnect the cluster connector. This connector has a tendency to feel like it is seated but you need to make sure it clicks in. A good test is to just give it a moderate tug and wiggle once you think it is seated.

If that fails to produce anything you could take the next step and pull back the rubber boot over the cluster connector while it is connected and check for voltage on the turn signal drivers when they should be active with a multimeter.

Yeah, I will recheck the connector. That sounds like a logical possibility. That would also explain why I am able to mess with the signal wires and get a result (I am possibly actually inadvertantly jiggling the cluster connector).

Thanks for the suggestions. I will check that during lunch!

Ok, I checked the connector wire. It was definitely loose. I spent a good 30 minutes playing with it. I can't seem to get it so it will stay no matter what. I have it in there as tight as it will go with the rubber boot on it too. I think the rubber boot actually helps it come apart!

It seems like a pretty complicated little connector, any suggestions to make it stay in tighter?
