fault code 46 and related issues

[nemoest]

So I was out and about on my bike getting some more practice in, when I noticed it died while I was waiting to make a left. Odd, but I was able to start it right back up, so I decided to head back home.

When I pulled into my parking spot, I decided to let it idle a bit to see if it would do it again. Instead, the check engine light came on and it threw fault code 46 (which I did look up, although I don't completely understand). I flipped the cut off switch and noticed the fan was on, and the temperature indicator was all the way at High.

Now, this made me think back to when I started it earlier. When I was starting it a few hours ago, it threw Err-Code 1 (as if the side stand was down, which it wasn't) and then the gauge cluster just faded away. I thought maybe the battery was dead and it didn't have enough power to start it up, but I was able to get it started after turning everything off, and then back on again.

I'm probably going to take it to Yamaha, but I was wondering if anybody had any ideas on what to check?

The coolant is in between min and max, the oil was recently changed and at a good level... if it's electrical I'm probably at a loss anyway.

Thanks

Hi. I'm no expert but it sounds electrical. I think the best thing you can do is take it to Yamaha and let them take a look at it. Below are the fault codes from the service manual that might help you.

You probley need a new battery.

You probley need a new battery.

This may or may not be true. The bike started so there was enough juice in the battery to take on the extreme load of the starter. So, it could be the battery but it may also be a charging system malfunction in that the system output is not sufficient enough to maintain charging but rather, only the run cycle. A systems test is clearly warranted.

 

[wrightme43]

Yes just general experince says two odd fault codes, a die off, a fade off, and the things not making sense, is a more than likely a battery problem. I have been wrong many times, but if I was trouble shooting with the description given, I would be load testing and output testing the battery. I have been wrong so many times, but that is where I would start. That and its a 2004 three years old and thats about battery life with out a good battery tender regime. LOL Like I said its just where I would start.

Before you get too far check three specific connections:
1- The main connector to the ECU. Located under the gas tank, remove the plug, look for moisture, reconnect firmly.
2- The starting circuit cut-off relay. Located under the LH side cover, this relay is very important to the operation of the engine, not just at startup. See image below for location.
3- The + battery terminal and the starter solenoid.

Hopefully this helps. Good luck.

And it's a good place to start providing you look at the entire system as well. In this case the bike started, which would indicate the battery was sufficiently charged when he left. Later, the bike died, which may indicate an inability to maintain sufficient charge to maintain the run cycle. This is why systems performance tests are so valuable.

I agree in that typically a factory battery has a service life of around 3 years. That said, I am at 42 months and my factory battery has never seen the likes of a tender nor has it displayed any issues relative to being weak.

Thanks for your help everyone. Just to let you know Cali rider won the prize. It was the connector for the ECU, it needed to be replaced. Now it's running just fine.

lets hope no one ever gets a 30 fault code

 

[reiobard]

ahhh yes, they call that the Captain Obvious Fault code

Captain Obvious...cute!
I'm just glad that, collectively, we make one smart person.

Seriously, Yamaha had to pay someone to program that on in there....

Lets say that you do in fact cause a fault code 30, would you really need to pull the code to see what the problem was? Not only that, do you think that the engine having trouble starting would be your first worry?

 

[DefyInertia]

Just curious, have you had the TPS changed out?
