T/C ABS reset

[02semiata]

So I have been driving around for awhile with the 30amp DSC fuse pulled that disabled the T/C and ABS system but... I want to put these systems back on. So I reinstalled the fuse but the DSC and ABS are still on and the ABS is still not working. Is there another way to reset this system ?? I also tried unplugging the battery but that didn't work

It should reset itself after starting the car on the first try. It has in our experience here anyways.

This may or may not relate to the question above but does anyone know if holding the DSC button for 10 second do anything special? I had to try since both my previous Mazdas did things when you held buttons for too long... so from DSC on if you press and hold the button it will turn off DSC (light on), but if you continue holding it for 10 or so seconds it will turn the light off (DSC on I assume) and the button stops working for another 10 seconds or so...

I did try a few things but nothing. Maybe somebody with a service manual can see if there is another way

Here's what I came up with, looks like a complete reinitialization and relearn is needed. Looks like there's no at home work around either. Here's the Alldata procedure :

DSC SENSOR INITIALIZATION PROCEDURE

WARNING:
If the initialization procedure is not completed, the DSC will not operate properly and it might cause an unexpected accident. Therefore, after replacing or removing the DSC HU/CM or SAS control module, make sure to perform the initialization procedure to insure proper DSC operation.
Inspect the wheel alignment and the tire pressure.
If there is any malfunction, adjust the applicable part.
Park the vehicle on level ground.
Switch the ignition to off.
Connect the M-MDS (IDS) to DLC-2.
After the vehicle is identified, select the following items from the initial screen of the IDS.
Select "Chassis".
Select "ABS/DSC".
Select "Sensor Initialization".
Then, select an item from the screen menu.
"Brake Fluid Pressure Sensor"
"Lateral Acceleration Sensor"
Perform the procedure according to the directions on the screen.
Drive the vehicle.
After 5 min or more of driving, verify that the DSC system is normal.

Dug a little deeper and Definately looks like a reset and reinitialization. ran through the diagnostic flow charts and all point to the Dealer or a shop with the OE type MMA scan tool Hopefully a warranty service call.

Thanks for posting. The first time it just reset when I reinstalled the fuse. No clue why its not working this time. I guess mazda will have to fix it
