Good afternoon
I just changed the oil and filter and my engine light came on ? After repeated turning off and on seams like I need to reset something like you do on a car… I’ve change the oil before but no engine light…. Did see a number 42?
Does this mean anything?

i also put on some new brakes on both front and rear- now my ABS light stays on?
any advise would be appreciated! Thanks

My oil light does the same thing unless I put the whole jug in. If I put in what the manual says to, my light stays on. 7 years later, 25k miles and no issues.

Code 42 is not oil related, but brake fluid. So there you have to look.

I see that you changed the brake pads, are you sure that the brake cylinders were clean before you pressed them back? Did you check the level before you pushed the brake cylinders back?
If the cylinders were not clean you can have created a leakage due to a worn out seal (due to dust). Or the level in the brake circuit is now to high, creating pressure or leakage somewhere else.

Thanks I’ll look into this

Check your brake pads and brake fluid level. As the pads wear away fluid drops. How many miles on your bike? If the problem is not self evident try a bleed / flush. Cycle the abs and try clearing the code.

If you are not able to resolve put it in the shop. Brakes are not something to fool around with.

Our clutch and brakes can let a small amount of water and air in. If the fluid has white crusty things in it , water contamination has occurred.

That's clear. The question is, how did you do it? Just swap the pads, or did you clean the brake cylinders and check the brake level?

If you just swapped the pads en pushed back the cylinders (and you never checked of cleaned your brake cylinders) you can have created a leaking seal. As the brake pads wear the brake level drops, sometimes this is topped off by the dealer. As you push back your cylinders the level in the circuit becomes too high and needs an exit, creating pressure or leakage in the lines.

Exactly how I did it
No cleaning just put in new pads
Darn it

Note that the latest versions of the Gen 2 (DP71) can only be reset/cleared by a special tool (OBD2 reader/clearer) due to Euro 4. Earlier versions can be rest/cleared as described above.

A method I learned (from here?) is to open the bleeder when pushing the cylinders in. Pressure doesn't go up the line at all... including not up to the abs unit.

It’s probably not your brakes.

I checked the manual, code 42 is the rear wheel speed sensor:

My rear wheel sensor was loose after I changed tires - my bad!
I looked inside the hole where the sensor goes
Didn’t see any pins but it could be dirty
What product should I use to clean the sensor and in that hole with?
