2005 with a code 30

[Pierre]

Bike in the heated garage all winter long. Everything was ok when I parked it. Try to start it, having a code 30. I changed the lean angle sensor, nothing, same problem.

I put a video on Youtube Fjr1300 code 30, it you want to see what happen.

What should I try?

Ignition fuse is ok

No help on code, but thought I could embed

... not this time.

Have a look at the connector in the sensor if everything is ok there,also pull the connector in the ECU and have a look there if the pins are ok in good and clean condition.Pull and push back the connectors two,three times..and have a look and in the wires there.I don't think that the problem is in the lean angle sensor..I have never heard for a defective lean angle sensor..

 

[Pierre]

I have replaced the sensor with a new one, clean the sensor contact, the ecu plug, and the ignition fuse socket with contact cleaner, same problem.

Diagnostic codes are explained and shown HERE. Go to diAG code #8 and read the value. 0.4 - 1.4 volts = motorcycle upright and able to run. 3.8 - 4.2 volts = motorcycle is tipped over and unable to run. What value is in your display? diAG code #61 will display a history of all codes the ECU has set. diAG code 62 will let you clear all history.

Turning the ignition key off and back on again is supposed to reset the Lean Angle Sensor error code and make the motorcycle Run = Able. If this is not happening something is wrong (which you already know).

Stored-in-Garage = mice. Using a meter: With the ignition key ON, at the Lean Angle Sensor the red/white wire should be battery voltage 12.8 volts(1). The black/bue wire should be ground. With the Lean Angle Connector connected to the harness connector, back-probe the connector, the yellow/green wire is the sense voltage going to the ECU and should be <1.4 volts or >3.8 volts depending on the state of the Lean Angle Sensor. If your wiring has had a mouse bite the black/blue wire would be the suspect wire.

Stored-in-Garage = mice. You should take a peek in your air filter and see what's in there.

Anyway, this is everything there is that relates to the Lean Angle Sensor and the Code 30 you see. Check it out and let us know what you see.

(1) I don't have a '05 manual. It is likely that my '04 manual is wrong and the Red/White wire is actually Blue which is the 5.0 volt reference voltage like all the other sensors. If it weren't -3ºF in my garage I'd lift my seat and look at the sensor. Maybe in May.

Well, after the last attempt on the video the battery has become discharged (that is why the display went blank), so recharge the battery before continuing.

Put the bike into Diag mode and read location 08 (lean angle cut-off switch). The normal ranges of values are: 0.4 - 1.5V = bike is upright. 3.8 - 4.2V = bike is overturned. If the Diag mode is showing above 1.5V then it has to be a problem with that sensor or surrounding wiring still.

One thing I'd be concerned with is that all of the sensors run off of a regulated reference supply voltage (Vcc) and common from the ECU, so maybe one of the other myriad of sensors on the bike has messed up that reference voltage? The three wires to the tip-over sensor are Blue, Black/blue, and Yellow/green. The Yellow/green is the sensor's signal and should measure whatever you saw in the Diag screen. The Blue is the Vcc and the Black/blue is the ECU common.

Especially where this happened during long term storage, do you see any evidence of rodents having chewed on some of your wiring?

(Damn... too slow again.)

PS - Wire colors changed in 2004. The colors I called out should be the right ones.

(Damn... too slow again.)

At least we have (mostly) consistent information.

 

[Fred W]

True. Mostly consistent. There really isn't much to this tip over sensor circuit.

But I do see now that the change between the '03 and '04 model years was more than just the color of the supply wire. In '04 (and later) the tip over sensor is now using the ECU's regulated Vcc (Blue wire) and in '03 and prior it was an unregulated 12Vdc from the ignition fuse.

 

[Pierre]

Great, let me check that tonight, and I will get back to you guys !

 

[Pierre]

Guys, it's fix, thank you so much.

It check and I have 4.0 at Diag position 8.

Meanning bike is overturned.

I double check the sensor, and i was about to measure the voltage on the 3 pins connector, and I notice one of the wire was splice.

It hits me, and I feel so stupid now, I had to splice it to install my Scorpio alarm in 2005.....

Battery in the remote was dead, change the battery, unlock the alarm, and the code 30 dissappear

AAARRRRGGGgggggggg!!!!

Spend so much time checking eeverything, spend $80 on the new sensor........

Thanks again!

 

[Mihalis fjr]

So,Happy end!!

You could sell the sensor..

 

[Fred W]

Interesting! So the Scorpio alarm used that particular signal to disable the bike from starting?

Hmmm... not very intuitive when it happens that this is what is going on. I'm surprised they didn't tap into the kill switch circuit and disable the starter entirely and keep you from running down the battery.

Glad you got it fixed.

 

[Warpdrv]

After Market alarm systems are mechanics nightmares.....

Speaking for automobile mechanics in our service shop..... They always down the line end up being big problems for diagnostics, and we always suggest to customers to NEVER install them....

Glad it was an easy fix for you and she's back up an running....

Thanks for your help
