After changing all the pads and sensors, I reconnected the battery, and when I turned the car on, every warning light is coming up (abs, psm, wear on brake pads, check engine, and sport mode failure).
Leading evidence: 'stupid mistake' (1 discussions report identifying this cause; no attributable repair resolution).

Turned out to be such a simple mistake thank god !

This weekend I changed the brake pads on my Boxster.
These are separate views of the same evidence. Frequency alone does not establish a fix, and these counts must not be added together.

I was wondering why this was happening and how I can fix this, as I even tried to disconnect and reconnect the battery once more, but got the same result.

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

When I first reconnected the battery, the idle was slightly off as I guess it was relearning the idle, but after 5 minutes it corrected itself and went back to normal.
This weekend I changed the brake pads on my Boxster. Before I started, I disconnected the battery. After changing all the pads and sensors, I reconnected the battery, and when I turned the car on, every warning light is coming up (abs, psm, wear on brake pads, check engine, and sport mode failure). I was wondering why this was happening and how I can fix this, as I even tried to disconnect and reconnect the battery once more, but got the same result. Also, I know that once the sensors on the pads goes off, the sensors must be replaced when changing the pads, but what if these are brand new pads?? Will i need to replace the sensors again? Any help would be greatly appreciated! Thanks
Did you try driving around the block to see if the lights go out? Various lights do come on after a disconnect but most of them are bogus and will be reset within a few hundred feet. It does look scary however!
Pete, I did the brakes at my friends garage a few miles from me, so I drove it home from there and the lights were still on and today I took it out for a quick drive and still the lights won't go off! I don't understand it.
Ugh, this is definitely a new one. How was the car running? The only other thing I can think of is that maybe the battery is low on juice, but you had enough to crank the engine so that maybe isn't a valid theory for now...
If your old pads weren't low enough to trip the sensor and brake warning light, you can absolutely reuse the sensors.
The car is running perfect...the sport mode won't activate, as it says sport mode failure with the rest of the warning lights, but other than that it's running perfect. When I first reconnected the battery, the idle was slightly off as I guess it was relearning the idle, but after 5 minutes it corrected itself and went back to normal.
I'm sure you already know this but here is my limited knowledge of our brake sensors.
As the pad wears down, it will grind away at the sensor "nub" that is embedded in the pad material. At some point, the insulation material in the nub will be worn through and the circuit will be opened or shorted. This "short" will be detected by the computer and the warning light will trip. The sensor is now useless since the circuit is now open.
A new sensor will have all the insulation material in place and the circuit will be closed and the computer will not trip a brake warning.
The taillight sensors operate on the same principle, when a bulb blows, the circuit is now open and a warning is tripped. A new bulb will close the circuit again.
The issue you're having right now seems completely different.
Wait a sec. I just realized something, hang on....
OK, I think I have the answer, but I need help from the more technical among us to confirm the details.
In the rotor area, there is another sensor wire in addition to the brake sensor. This other sensor is the PSM/ABS sensor. IF this wire is cut or loose, you will get PSM, ABS and who know what other errors because the ECU of the car can't "see" what the wheel is doing anymore.
I don't know how his sensor is connected, but it is quite possible it was dislodged during the pad/sensor replacement process!!
Bingo, look at post #6 and #9 here:
http://www.planet-9.com/cayman-boxster-tech/34548-brake-problems-after-pad-change.html
Wheel rotation sensor! The wire is right next to the brake sensor wire. I hope this is it!
Chris the question I have is why did you disconnect the battery? There is no need when you are just doing a brake pad change.
Maybe you can find someone with a Durametric tool to help you. Where in NY are you?

Got stuck yesterday at work so I wasn't able to check it out but hopefully when I get in tonight I'll be able to take a look and let you know how it goes.
Honestly, it was just dumb. I figured that since I was changing the sensors to disconnect the battery because I didn't want to short anything. Looking back it was pretty dumb. I'm located right off the bridge in Brooklyn. Hopefully one of the sensors are loose and just need to be plugged back in.
Looking forward to seeing what you find.
The brake sensor wire is held by a clamp attached on a suspension component. The clamp flips up and out of the way to let you remove the sensor wire. The wheel rotation sensor wire is right next to the brake wire and is held on by the same clamp.
Yep..I had put in new sensors so I'm hoping that maybe I was just careless and forgot to plug one back in. We'll see in the morning. I'll keep you guys updated.
So, today I got to work early and put the car up on jacks and searched each wheel again. Turned out to be a stupid mistake ! haha I had spoke to Pete on Thursday night and we were going through what it could have been, but it turned out that I had accidentally switched the pad sensor wire and abs wire and that was causing the lights. Switched the sensors back to where they should have been and the lights all went off within 100 feet :banana: . Turned out to be such a simple mistake thank god ! Thanks for all the help guys
Pete, you and me both. I really didn't know what it could have been. I honestly don't know how I did that because I hadn't even unplugged any of the ABS wires ! or maybe i did..but thankfully it was a simple mistake that was solved pretty easily. Thanks again for the help
Congrats on finding the solution. That is why this forum is so great. On a slightly related topic I also replaced my pads after both rear sensors tripped. I did not replace the sensors, rather I tied them back with wire ties because my new pads didn't have hole drilled in them. When I was changing the front pads, I broke one of the sensor wires. I cut the sensors off the wires, spliced the wires together and tied them back. When I turned the car back on, surprise there was no brake warning light.
So I completely agree with PistolPete. As long as the circuit isn't shorted, it will not trip the fault code even with loss of insulation and even without the sensor.
The same thing just happened to me. I accidentally switched the ABS sensor plug with the Wheel Rotation sensor plug, and neither was fully plugged in. The ABS, PASM, Brake, and Engine lights all tripped. I went back in and reversed the sensors, and all went away except for the check engine light. Hopefully the warning system is just a bit confused after the mixup, and is going to recover after a little while. Only other thing I can think of is I jacked up just the front end, so maybe oil sloshed around in back? Fingers crossed it clears up soon, or else maybe I'll need to get the computer reset.
