ER - 3 .......56 error

[Trumpeter]

Hi everyone. I hope someone can help.

My 2004 is a great bike but recently it has developed an intermittent fault.

Occasionally when I turn on the ignition I get ER 3 followed by 56 and the bike will not start.

Trouble is this can happen at any time, and then not again for ages. When it does occur if I leave the bike for a while it's OK

It's now happened several times when I'm out, the last time I called recovery as it wouldn't clear, as they arrived it started!

I've looked up the error code but can't seem to make any senses of this, if it happened all the time or if something changed between it working and not working it would be easier to fix.

It's got to the stage where I can't trust the bike to be ok if I'm out and I'm not riding it.

Any ideas.............??????

Many thanks in advance

Mike

ER-3 is:

Data from the ECU cannot be received correctly

Which means that the meter assembly (dash board) is getting invalid data from the ECU. This could be a bad ECU, the harness that goes to the front cowling harness or a defective meter assembly.

Are you sure about the 56? There is no code 56 listed in the FSM, well at least it's not in my FSM.

A simple place to start troubleshooting is at the ECU connector. This connector is supposed to have locking tabs to hold it in place but they often get broken or not clipped back in place when someone does the Barbarian Jumper mod to enable the CO trim function through the diAG menu.

Thanks, I've spent all morning trying to replicate the problem, turning the ignition on and then off, starting the bike and all was OK. Decided to go for a spin, turned on the ignition and there were the errors,!!!! Pushed the bike back into the garage and tried several more attempts but still the errors. Then without touching, moving or changing anything everything was OK again.

ERRORS

Er-3 flashing and alternating with 56...... And occasional Er-1

I captured a short video on my mobile, I'll see if I can work out a way to post it.

Thanks again, if I had any hair I'd be pulling it out!

ER-1 is also a 'No output signals received from the ECU'. A connector is still suspect #1. The connector on the ECU should be checked first, then the communications connector between the main wiring harness and the front main harness then at the back of the meter assembly. The communication connector between the main harness and the front main harness may have corrosion.

It seems that turning the key ON/OFF doesn't provoke the problem but moving the bike (shaking, vibration, movement) does. This strongly points to a connector or pin being loose or corroded.

What is the check engine light doing? It should normally be on for 1.4 seconds when the key is first turned on, but under error conditions it may flash at certain rates or come on 100% of the time. All codes that begin with ER-x will inhibit the engine from running.

All the connectors in the FJR are unique in some way, either by shape, pin count or the number of wires in the connector. When I give the description of a connector it will be unique, not to be mistaken for any other connector.

Raise the gas tank. The communication harness connector is up by the steering head, under the T bar and will have 6 pins in two rows of 3 and will be populated with 4 wires, leaving two holes unpopulated. You want to check the Yellow/Blue wire which is the serial communications wire between the ECU and the meter assembly. The other connector, in the same general area is 18 pins in two rows of 9 and will be populated with 13 wires, leaving five holes unpopulated. You want to check the Black/White wire in this connector, it supplies ground from the ECU to the meter assembly.

Thanks for the replies, I've uploaded a short video on youtube.

Hopefully this will help, immediately after this was filmed I switched on the ignition again and everything was fine...I didn't change touch or move anything, just turned the key again.

Thanks again

Looks like errors 1 and 3, I'd guess the 56 is the temperature that gets displayed between error displays.

Gen I doesn't display temperature. We know it's a Gen I because there is no ABS light.

The number 56 is a mystery, neither Gen I or Gen II has an error code 56 listed in the FSM. The Gen II does have code 57 if the FJR has the heated grips option. Could this FJR actually have 56 failure codes in memory? Edit: I believe the error code count stops at 21.

The OP can click >>HERE<< and see how to read codes, check for stored codes and clear them using diAG. Code 61 is where all the failure codes are stored and Code 62 is were the codes are erased.

(Ok, not temperature, saw the little 'F'.)

When the 56 is displayed, there's no "Er", so I don't believe that is an error number as such.

Thanks for the replies, I've checked the wiring and it's all good.

I have discovered that by switching the ignition on and pressing and then letting off the starter button quickly I can replicate the problem. If I move the engine on a touch by the same method the error clears? Really strange. I've moved and wiggled wires but nothing makes any difference so I'm pretty sure it's not wiring related, could it be the crankshaft position sensor even though the history shows no errors?

Hope someone can shed some light as this is getting really frustrating !,!

I notice the display blanking on subsequent start-ups, it might be worth fixing the (presumably) low voltage condition causing this, could be battery, connections, starter relay, starter motor.

[edited to correct typo, "banking" to "blanking"]

 

[Trumpeter]

Could all of this be caused by a failing battery?

Thanks

I would be very suspicious. As I said, fix the obvious "low voltage during cranking" problem, maybe the errors will disappear.

 

[lnewlf]

check all the grounds

 

[ionbeam]

If the voltage drops far enough it will cause the ECU to stop communications with the Meter Assembly. Perhaps it's as simple as a loose cable on the battery. A sure symptom of low voltage is the clock and trip odometer resetting.

Low voltage and resetting displays isn't that uncommon, but resulting codes ER-1 and ER-3 has never been reported before AFAIK.

Yes. Do the simple stuff first. KISS!!!

If the battery is rulked out check the wiring from the battery and alternator to make sure you are getting full battery voltage to the rest of the harness, and also as suggested, that the ground paths are good.
