Hello.

I have retrofitted MRCC for my CX5 2017, it worked but have a problem with Stop&Go.
- In case, if AutoHold is turn off (not enable) I got this message: "Mazda Radar Cruise Control Disabled under 20 mph".

- If AuoHold is turn on (enable), no message at any speed, MRCC working well and can decrease to 5km/h, but not complete stop, I must manual depress the brake pedal to stop.

I dont know why I need to turn on Auto Hold to using MRCC because Stop&Go MRCC will take care of it automatically no mater your auto-hold is already enable or not.

The Radiator support core for the non MRCC model is different and is missing the bolts to attach the brackets. so I had to think on a solution for this.

so I made the nuts with a M6 rivet nut kit that I ordered on amazon https://www.amazon.com/gp/product/B01M59GTH8/ref=oh_aui_detailpage_o02_s00?ie=UTF8&psc=1


then I had to do the wiring. so I added two lines for the can hi and can lo on a joint connector that is located near the windshield water tank.
add ground and +12v ignition from the correct circuit.

I also added the as-build values for mrcc and distance support.

the only thing left is the calibration that I hope will get done this night.

BAEK-67-XA1C and yes it works

Hi, I'm very curious, have you figured out this problem? I have the EXACT same message/problem with mine after retrofitting MRCC in my 2017 CX-5. Please let me know!

You have two option:

• Change As-built data to MRCC without Stop&Go, so MRCC will working from 30km/h.
• Replace your ABS unit if you want Stop&Go function.

So if I understand you correctly, my ABS unit is incorrect? Even though my car has Auto Hold from factory?

My ABS unit part # is KB7W 43 7A0B.

Your ABS does not support Stop&Go.

 

[acastrolee]

I doubt it, check your as-build there's plenty of people that already did this retrofit with the stock ABS pump
