R1150GSA GS-911 Fault code 277

[Stujw70]

Bit frustrating, after thinking the new temp probe had resolved the issue as the bike seem to start all well & good earlier today. Ran the real time values with ignition only as suggested with screen shot below and the bike had been sat for about 4 hours since last run so engine cold.

The new temp probe seemed to show as being serviceable with the multimeter against yesterdays temp range as given on the image earlier in the thread.

The initial fault code 277 showed: Engine Temperature Circuit Malfunction, Short-circuit to Earth

Since fitting new temp probe fault code 277 shows this: Engine temperature circuit malfunction, short-circuit to positive or open-circuit

Stu. Unplug the sensor and see what you get then for the RID and GS-911. It seems like you have a short.

If you run the engine does the oil temp go up?

I was off work today, so once the rain had stopped I whipped the fuel tank off again after noting that the RID dropped to x2 bars when the tank was connected up. After this I progressively cleaned and removed every electrical plug I could access and looked for loose/ busted wires along the way. Undid all the looms around the headstock and stripped back the collection of wires bundled together under the clocks. All seemed good.

So once all back together again, I ran the GS-911 again looking for real time values. Again it still showed the high engine 60c temp even with the new temp probe disconnected. After this progressively disconnected the various plugs and eventually the actual RID loom. This time the engine temp showed as being matched pretty closely to the air temp.

Bundled all the cables out of the way temporarily and fuel tank back on. One click of the starter button and away she went.

RID now removed and the circuit is pretty knocked and one wire burnt through. Assuming due to water ingress.

Fingers crossed this time, it is resolved Or will be once the second hand unti arrives from James Sherlocks.

Stu, It sounds like you've got it. Was the old RID burned or corroded?

I don't see anyway that a condition on the loom could have fried your RID unless one of the lines, other than the two +12V lines, is shorted to +12V. It is worth measuring all the pins on the loom side of the RID connector, with the RID unplugged, before you try the new one.

In case you don't have it, here is a schematic with the pin out. RB

Photo of the RID internals, not sure if the melted green wire is a earlier repair attempt of the circuit board.

My RID failed but I didn't have your starting issue, the unit just stopped working! When I took it apart it had bad corrosion in the same place as yours but without the burned out wire (repair) and I realised that it had been leaking for some time with water getting in through the 2 little adjuster pins for the clock, someone had probably been using a small screwdriver to adjust the time and pierced the rubber!
Make sure that you have a good look at the replacement unit in case that it has started to do the same

Good old James Sherlock, less than 24hrs and 2nd hand replacement RID arrived. Unit checked, cheers mspenz, Bike stripped again as couldn't wait to go out for a ride last night, new unit now fitted tested and looms all secured. All working as it should now.

I spent quite a bit of time barking up the wrong tree when I first purchased the bike and realised it had a starting issue. New main coils, new spark plugs, sent the injectors away for cleaning, ordered a new fuel pump and filters expecting it to be on the fuelling side of the bike just due to age & mileage (92k). Even fitted a new battery just in case.

As you can guess I was running out of options, so I took the plunge I managed to picked up a second hand GS-911 and this immediately pointed me in the direction of the suspected temp probe. As was noted after fitting that still didn't resolve the issue. What I wished I had realised earlier is to disconnect the RID as it had never given a true reading since purchase. But as found, I didn't realise it having a fault would be reflected back into the running of the bike.

I'm know mechanical or electrical expert so lots of lessons learned, and it gave me the chance to have a good look over the bike.

Thanks for the help, Off for a ride now

For somebody who says they're no mechanical or electrucal expert, you have a damned fine grasp of things! Glad you got it sorted. I'm currently 3 weeks into 1150 GSA ownership and its love!!

Thanks for that, but really would have been working blind without the prodding in the right the direction from on here. ��

Is the replacement of the RID straightforward (wiring connections) or does it involve some soldering to join wires? Mine swaps from working to not for no reason and I'm considering getting a replacement. Wondering though whether its intermittent working is the unit itself or a damaged wire somewhere in its loom.

Steve,

It's pretty straight forward. Remove screen and silver cover. Undo the centre bolt which holds the clocks support bar in place and tilt the clocks back towards the handlebars. You might need to undo the top speedo cable attachement. Once the clocks are tilted forward iirc it's 3 or 4 screws holding the RID unit in position.

The loom is attached underneath the fuel tank if you are happy taking it that off. The right hand group of plugs in the photo I'm sure is where the RID connects.

James Sherlocks supplied a used unit in less than 24hrs, but not cheap £70+ I think
