Gear indicator

Can you get a picture or quick video of what you are seeing? The reason I ask is I am thinking this is normal but seeing it will help figure out what is going on. Also, is this something that just started happening or did you just buy this vehicle?

Now I understand. Thank you. Does it ever go off when you shut the vehicle off? Or does it stay on all night and it is on when you come out in the morning?

Clearly I agree that I don't think that is normal so let me know if it is ever off and we can start figuring this out.

So the way this works is the cluster gets the signal about what gear the transmission is in from the range sensor on the transmission. However, it gets this signal from the PCM so there is no direct connection to the range sensor. I suspect the cluster itself is the issue because I have not seen any of these stay like this. However, before you replace this, let me reach out to a Honda dealer contact that I have an ask if they have seen this or if it is normal. Even though I have not seen them stay on, it may be the way they are so let's just double check that first.

I will let you know what they say. Thanks

Sorry for the delay. They initially said it doesn't sound right but he wanted to check a similar vehicle but never got back to me today. I will follow up with him tomorrow.

However, one thing we can do is test the ignition off draw of the vehicle and see if it is within spec. So this way we can see if there is an issue even if it is not normal. Basically if the ignition off draw is within spec then it doesn't matter if it is not normal because it won't drain the battery. Do you have a multi meter?

Okay. Let's just go ahead and do a draw test and then unhook the cluster and see what the draw drops too.

Here is how we do this in case you are unsure. Set your meter to milliamps. Make sure you red lead is in the correct port for amperage and then the black lead is in the normal ground port.

Unhook the negative battery cable and connect the leads, one to the negative battery post and then other to the negative battery cable. Then tell me the amperage or just take a picture of the meter and then unhook the cluster and let's see what it drops to.

To fix this, I suspect the issue is contained in the cluster because it looks like the PRNDL lights are controlled by the drive circuit contained in the cluster.

Let me know if you have questions about this and we can go from there. Thanks

Okay. I am not sure that is the correct reading because if it is 11.54 amps then your battery would be drained in about an hour. What was the setting on the meter? Maybe that is 1.154 amps?

Here is a video that shows the set up just to be sure we are on the same page:

Amazing. If you can track the wire to one end or the other to see what component it is going to, we can figure out what it is.

Thanks for the update. I would love to figure out what wire that was. Great job!

Great information. Thanks for updating us and great job again figuring that out.

Yes. Sorry I forgot to provide that. It appears the white wire going to the PCM and is the CAN Hi line which if the voltage is off would cause the gauge to act up. Clearly the voltage was having the PCM illuminate the P all the time.
