2016 Mazda6

Has an electronic parking brake.

Replaced rear pads and rotors. Used the online procedure to put the EBP in service mode. Something seems to have not worked out correctly.

Everything is back together but the car will not start and getting a bunch of errors(keyless system malfunction, Snart city brake support malfunction, Foward SCBS disabled, Blindspot malfunction, window washer fluid low). Non make much sense but I am sure it's related to the Electronic parking brake.

Any help would be greatly appreciated. We are out of town with a car that will not start.

Added battery seems to be low now and there was a low wrolling? sound in the engine bay when doing the work and the EPB was in service mode.

Did you try jumping it? Sounds like a dead or dying battery

Got it jumped with a jump pack. It will drive but the brake like is flashing which means a fault/issue with the parking brake.

Also, the light that means it's in service mode is still on. Every attempt to use the procedure I found online to take it back out of service mode does nothing.

Currently, have the battery discounted to try another reset.

My concern now beside the EBP not working is with the car off I hear a humming in the engine bay. I heard this before after putting the EPB is service mode. My concern is this is going to cause the battery to drain again.

While I am not happy with the warning lights that are on and the EBP not working those do not make the car undrivable. The humming is an issue though as it will continue to discharge the battery.

I'm sure noise has to do with the EBP.

I've done the brakes on cars many times but never dealt with an electronic parking brake until today.

Do the OEM rear brake pads have wear sensors?

Finally got it figured out. What a PIA. Seems somehow the battery getting drained some screwed everything up.

After getting the battery charged I removed the negative cable and let it sit for 45 minutes.

After reconnecting the battery still had the issues. Then I went tried taking the EPB out of service mode. No, go there. I tried that a few times. Then I decided even though it showed being in service mode maybe I should try and put it into service mode.

That procedure turned off the flashing red brake light. OK, somewhat success. Next, I went through the procedure to take it out of service mode and it worked. All the lights that were on went out.

Just give me a normal braking system.

Comet - this seems to be a common issue on a lot of vehicles, especially newer ones.

From what I can tell, people are buying those battery saver tools that you can plug in to your OBD port and it saves everything as if your battery was still connected. Not sure if it would help you here but all of my BMW friends say they have to use them whenever they disconnect the battery to avoid these types of issues.

Crazy. Seems like the frustration was the worst part of it.

I had a similar problem with a Bosch Series III ABS system. Lost power a few times and it kept running the system self test each time. Lucky me, the pump overpressurized the hydraulic accumulator, blowing out the pressure sensor. It was supposed to stop at 2600 PSI and the sensor was $300+. Yay!

Check you negative battery post is secure and tight. Amazing what problems that can cause in a modern car.

About a month ago, the battery that had been in my car for many years started to show signs of being ready to poop out, so I took the preemptive measure of replacing it before it died and left me in an inconvenient place.

While I was at the counter paying for the battery, one of the store guys took it out to my car and installed it. Sort of.

I got out to the car and saw him whacking on the starter motor with a piece of wood that looked like something you would get nine months after an axe handle and a baseball bat had unprotected sex.

"What are you doing?" I asked.

"Your starter motor is stuck," says he.

Having spent a number of years trouble-shooting and repairing radar systems and communication and navigation radio systems, I learned that the most likely culprit if there is a problem after maintenance, is the last thing that was messed with.

I grabbed a battery cable that was nowhere as tight as it should have been on the battery post; there was some free play.

"I bet that if you tighten this clamp, the starter motor will be fixed," I said.

Yup. That solved the problem. (I may be a Geezer, but I have actually replaced a few batteries. Before that "technician" was born. Maybe even before his parents were born.)
