Z1000R engine management light on.

I know this may be a long shot but, has ANYONE had a problem like mine......I have a 2018 MY z1000r performance edition registered in May 2019 and is not yet 4 months old.I bought it new and its done less than 6000 miles. The problem is that sometimes the engine management light illuminates when travelling, and at the same time I lose the digital gear position indicator function on the clocks.This shows as error code 25. After a few hundred miles the light goes out and the gear indicator starts working again. The dealer hasn't been much help so far as his error code list suspects the ABS/ speed sensor at fault, the same as my z1000 manual/laptop pdf. Unfortunately none of them seem to cover or take into account the gear position indicator of the z1000r. Regards.

Has the ABS/speed sensor been replaced yet ?

No, as its an intermittent fault all components checked out ok when the dealer tested it [this was before I knew how to retrieve the error code 25, which didn't show until the fault was in evidence. I was 150 miles from the dealer when it occurred again] The thing is when the E.M. light comes on, the gear position indicator doesn't work, which would point to a gear position sensor, not ABS/speed sensor. Error code 25 could be unique to only a z1000r with a GPI fitted as standard but there is no reference made to this in any information I have, or the dealer looked at for guidance. Hence, I ask if I'm alone with this problem.

Quick way to test it, could be to disconnect the ABS sensor under normal conditions (engine light off) and see if you loose the gear indicator function. (Of course the engine light we be on as well once you disconnect the ABS sensor). I am not sure how the gear indicator is calculated, but it might use the ABS sensor to monitor the wheel speed and compare it with the engine RPM to determine which gear you are in.

Do you really need a gear indicator ?

I would ask how come you don't know what gear you're in, but I find myself looking for 7th gear all the time.

I don't need a gear position indicator, the bike came with one as standard. The problem is that when it doesn't work the engine management light comes on and fault code 25 can be retrieved. It's the engine management light illuminating thats the problem, because if something serious occurs I won't know, as the light is already on!

Although the fault code suggests an ABS/censor fault, I don't believe it has anything to do with the ABS as that is working fine. Disconnecting the ABS censor from one wheel would illuminate the ABS warning light as well as the EML. The gear indicator can not calculated from ABS censor/engine RPM, when I changed the gearing...+1 on the front and -2 on the rear sprocket everything was working fine for 3000 miles afterwards. [It now feels like it has a 7th gear]

Hi Kenyun

I have the same issue with my new Z1000R I received a few weeks ago. was all good and then took it in for it's 1000km run in service. the mechanic put a 39T sprocket on the rear. Rode the bike for at least 150km afterwards and all was good until I stopped to chat to a mate and realised the gear indicator was flashing and the engine management light was on solid. Now only 'N' displays on the gear indicator when in Neutral but no other gears show. My mechanic says that the bike needs to learn and adapt to the new gear ratios in order to calculate gear. He recommends a few more rides and then all will be sorted. I just want to get your take on this seeing as u have first hand experience of this issue.

Am I correct in understanding yours was rectified only after you changed your sprocket gearing? I'm going to get him to revert back to the original sprocket just in case and hope it resolves the issue.

I have to admit it has reduced the revs when cruising at highway speeds nicely and the monster still pulls like a steam train but I would rather have the engine management light reserved for more important issues later down the line.

It seems that I am not alone with this problem after all. Mine has the same symptoms as yours plus a few other connected "ailments". After the first 600 mile service I fitted new 16 tooth front and 41 tooth rear sprocket and the ride was greatly improved as the bike was far too low geared. At just over 3000 miles the gear indicator light problem first occurred but disappeared after 200 miles. It happened again about 1500 miles later and stayed for 2 days. I managed to get it booked in at the dealers for the next day, but as I set out the EM light went out and I had a gear indicator again. At the dealers no fault could be found as it had not saved the fault code. Tests were carried out but no fault code found. The dealer conferred with Kawasaki and they suggested that if it happens again I should retrieve the fault code from the clocks, it did, and I retrieved fault code 25. It has been OK all weekend [so far], its an ongoing intermittent fault which I suspect is unique to Z1000R, specifically the gear position indicator sensor fault code/wiring which isn't included in the current manual, the closest code 25 gets is to point at ABS.

The other "ailments" that I referred to when the fault occurs, not every time but sometimes the green neutral light will not come on and when that happens the tick-over is either too high or so low that the engine cuts out even on closing the throttle to change up into 2nd gear, it has done that several times. As every piece of information goes through the ECU I can only assume that it is getting confused. [I know how it feels] I still have the higher gearing fitted, I don't think thats the cause, but who knows what the ECU is thinking!
