OK on my third day of ownership I encountered my first error code, 2 flashes followed by 1 later which is code 7. I was sure it was related to the temperature because I used it at 0 celcius. A small amount of snow was on the bike, really small, when it occurred. Now I saw it is related to the contactor. So is this due to the temperature or the snow?
2 minutes later, back at home, I plugged it. The battery level was still at 100%. The temp and charging light flashed once and after that the charging light was solid green. I think it didn't want to charge due to the temperature, or the battery was still full.
Any comment?
-
I forgot to say that I turned the key off and on and the bike started normally.

Can you put your bike in your sig so we know what model to reference?

I had persistent red flashing lights for what was a driving rain once that really soaked the bike, which cleared up after riding the bike for about 10 miles in dry weather the next day along with 4 or 5 times having flashing red lights from the battery pack getting too hot here in Texas summer and not wanting to recharge until an hour or so when it cooled off. The bike has never stopped running though. The only other thing I have gotten a few times is the bike not running with the first boot and I have to reboot...then it has always gone on the second boot. No warning code appears with that. It just won't go until you reboot. Oh yes, I did get the warning light for riding too fast a couple times but that is very predictable and you just slow down and it stops flashing right away. The sensors do seem to work to protect the bike.
From your description, I seriously doubt your code was due to moisture cause I think you have to get it up under the seat into the controller to cause that fault. Probably the cold, although I have never had a code from cold, only heat.
-
What model and year do you have? On my first Zero DS 2010 I sometimes got error codes but after reboot I worked.

sorry, done

I may have done something the computer didn't like:
I turned the key on at the same time that I removed the stand and played with the throttle at the same time.

My reboot-in-the-morning minor glitch seems to be dependent upon temperature. It never showed up all summer and then one day last week the temperature in my garage dropped into the 40's and my 2012 S needed the ignition key turned off and then back on before it would start up. When this happens I will not hear the contactor "click". But when I turn the ignition key off and then back on, the contactor will click and the bike will respond to the throttle normally. There are no fault codes showing. As near as I can tell this issue is entirely dependent upon the temperature of my bike in the morning and once warmed up above 50 degrees due to ambient temperature, or due to operation, the problem doesn't surface until it gets cold again. It appears to be no big issue and I have learned to live with this feature of my bike.

I have the same issue on a Zero S 2013. it also happend when the bikes starts from the office parking (heated), so I dont think it is temperature related. And I often have to turn key off and on again 2 to 3 times to start it.
I am a bit nervous, because I had the same issue with my XU, before it started stopping brutally in the middle of the traffic... I talked to the dealer, but i dont think they have a solution...
-
Same for me on my 2013DS, low temperature but not freezing, code 5 at key start with zero bar at battery level. Reset and then ok with 100%. Nervous ? For sure, I'm selling all my ICE bikes now so won't have a spare to go to work !!!

I notice that the throttle won't engage and the double-blink-long-pause happens when I turn the key with the emergency cut-off disabled. I find I usually have to be sitting on the bike and ready to go, pull up the kickstand, turn the key, let it start up, and then disable the cut-off switch. It's also been unusually cold lately. :/ I miss riding! But I don't want to chance getting stranded when the temps dip below 20F. :(

I heard of this happening too and have not experienced it yet on my 13 ds. I heard in the cold weather the capacitor that puts enough power over to make the contactor connect loses power (drains) in the cold. One key cycle charges it up and then will work with no problems. Not a big deal the lights flashing error is saying the system boot failed because it doesnt have enough juice to kick the contacts over
-
If the contactor wasnt throwing you wouldnt have any power, so you wouldnt see anything on the dash at all. It could still be the pre-charge capacitor though.
-
All right, let's see if the issue occurs again next summer.

Are you sure? or do you reckon it is so?
-
On my last EMS GPR-S, the contactor would fail most of the time when I braked to a stop. Everything would work, but the motor was not getting any juice. The bike had an old Sevcon controller and I had a programer for it that indicated a "contactor error" when these failures occurred. If I waited exactly 3 minutes, the bike would start up again and run for a few more miles until it happened again. It wasn't long after that that the BMS failed and took out all 24 batteries in the bike's pack. :(

My heated grips and headlight don't work until the contactor throws, unless there is a secondary circuit on the DC-DC with a separate relay?
-
Strange, I know that the headlight on my ZF9 will come on even if the contactor fails to engage.
-
I had the same issue. My dealer told me that they had a fix for it.
-
Well my dealer did the fix (bike software upgrade) and ... I still have the same issue.
It does not seem to be temperature related (it happends when I'm starting the bike outside as well as after one day at the office's heated parking):
- no "click" when you turn the key on
- red light flashing twice quickly, a pause, then one
- if I turn off and on several time i finally hear the click and am able to start

Your office heats their parking garage? That is madness.
-
Well they dont heat it specifically, but since it is an underground parking, and office are above, it stays at a normal temperature. So the key start bug is probably no related to temperature...
-
The red light flashing quickly twice, pause, and then one is just the fault indicator showing that your contactor hasn't closed when it should have. I don't think it has any other additional meaning.

About 2 months ago, My 2013S wouldn't go with the first boot up. Reboot and off I went. Then it seemed like every few startups it needed a 2nd boot to go. Now it always takes 2 boots to get the bike going. Everything looks good to go with the first boot, but twist the throttle and nothing happens. Turn the key off and on and after the reboot, you hear a click and it is good to go. Whatever that click is, I don't think I hear it with the first boot, and although it seems to be related to cooler weather, I can't say positively it is. Is that a contactor sound?

My 2012 bike does exactly the same thing. I am pretty sure that the "click" is the contactor switch activating.
-
Thanks Richard. So long as it stays that way, no problem. I just wouldn't want to have to keep rebooting more than twice like someone else reported needing to do. Short ride today. AF1 replaced a turn signal relay for me and I rode it straight home and plugged it in since we are having cold weather. 46F for a high. Even 6 layers of clothes didn't keep me warm enough to do any more riding. I think the cold snap is over after today though...Unfortunately, now comes the rain.
-
I had the exact same issue 3 times since yesterday, always when I turn the bike ON, but not happening after being disconnected from charge. It was 5 Celsius. Repetitive so I'm not worried.
-
Upgraded firmware at dealer today, he said that it may resolve the contactor error, we will see.
-
It should. The new firmware fixed my problem. Haven't had to re-boot even once since the fix.
