Hi all,

my virgin thread in this forum, lol.

Alright, I owned a 2017 Mazda CX-5 (2nd gen with GVC) and it is coming with Forward Sensing Camera (FSC), Smart City Breaking System - Front (SCBS-F), Blind Spot Monitor (BSM), Rear Cross Traffic Alert (RCTA), and Adaptive Front Lighting System (AFS).

Currently, I'm very interested on activating the High Beam Control (HBC), Smart City Breaking System - Rear (SCBS-R), Lane Departure Warning System (LDWS), Lane-Keep Assist/Lane Keeping Assist (LAS/LKS), and Driver Attention Alert (DAA).

From the Excel Sheet I found from this forum, kudos to @SergSlim and team for hard work, it is possible for my unit to active all the function I mentioned above? So far, I only found

SCBS-R:
720-04(3)-16 B0&B2
DAA:
720-04(3)-16 B4 <- Assumed will show something in MZD, but is it functional?
LAS/LKS:
720-04(3)-18 B0 <- Assumed will show something in MZD, but is it functional?
LDWS:
720-04(3)-18 B0 <- Assumed will show something in MZD, but is it functional?
HBC:
Did anyone managed to make it work here? Been browsing a lot in this forum but dont see a good answer yet.

Please comment. Cheers.

If you connect to your car using forscan and go under the dashboard tab, add the FBCM and the ESS status PID, What does it say?

Regarding to the FBCM that u changed to trigger the ESS function. Can I have your original code?

I want to compare with mine.

Anyway, heres mine.

726-01-02 66 AA D3 54 56 BD

the codes that the other guy gave enabled ess AND fog lights while high beams on (bambi mode)

thanks man.

I need more info and try to pinpoint the exact bit to active ESS. I didnt aware of the Bambi mode at all, i didnt know the fog lamp off itself when high beam is on.

will get back to you once i analyzed your data compare to mine and the other guy.

Cheers.

i found there is only very minimal difference btween ur data and the other one. and i suspect 726-01-02 B3:b1 = 1 is the answer for ESS.

by the way, what is bambi mode? I tested my CX-5 2017 (Malaysia) and my fog lamp can be switch on while high beam is on.

 

[hahaaha]

you are wrong, your 26-01-02 B3 and reeeeeeee's B3 are the same (54), so are you already get ESS without any chnages ?

Nopz, ree is 54 while the one who did it is 56.

im still bz from PC. not trying it out yet. mayb tomorrow or something

 

[hahaaha]

I just went out and did a bit of digging into the FBCM. in 726-01-01: Byte 0 bit 1,7 Byte3 bit 1, 6 enabled auto headlights and auto wipers as well as Bambi mode. This also gives some DTC about a low beam relay. It is too hot for me to explore more right now.

Then in 726-01-02 Byte 0 bit 1, Byte 1 bit 0, and Byte 3 bit 1 enabled ESS. I believe you need these bits as well as one of the bits from the previous block to enable ESS.

I can conclude 726-01-02 has no related to ESS.

 

[hahaaha]

My 18 CX-5 does have the ESS, auto headlights and auto wipers but no Bambi mode, and here is my F_BCM asbuilt. Compare with yours to see which bits are really related to ESS and others.

MAZDA: ESS | Active Safety Technology

How interesting.

I have bambi mode, my Fog lamp is on with high beam on. We both have auto headlight and viper. But i dont have ESS.

I just compared our F_BCM, we only got 1 different, which is

726-01-01-F2 (F3 in your case) 66 21 6A D8 EA (your check sum is EB, which is logical.)

 

[hahaaha]

Hi hahaaha,

According to edyvsr's last post, your B3 byte of 726-01-01 is "6A" so I guess your ESS is enable already.

im very sure my CX-5 2017 edition has not come with the ESS.

I tested to changed 726-01-01 B0:b0 = 1, no ESS too.

I start to think is it with the B2.

If edyvsr is correct, then it must be in 726-01-01 B2 which has the most different compare to mine.

cheers.

we are talking and testing on a mazda 3, not a cx5. I believe it is byte 3 bit 1 because thats one of the ones Ive set to make it work. At least on a mazda 3.

I aware if that and surprisingly, i activated some of the function by taking the the reference of Mazda 3’s input, such as HBC.

So i gonna try my luck once more here. N then i will compile my own coding.

Make sure youre looking at byte 3. in your post you said byte 2 so I tjhought it was just a atypo but I want to make sure.

My byte3 was the same as the edyvsr.

I’m testing on B2 tonight to see if it works.

Cheers.

One more add on. I compare this to another guy who activated the ESS, I’m very suspect about the Byte2. Wish me luck buddy.

 

[hahaaha]

ok, good luck

Tested. no luck

 

[hahaaha]

What do you mean? Same situation?

nopz, mine work pretty well for the find my car thingie.

just press rapidly with minimal to no delay and then the car honk honk.

ok, good luck

i copied whole F_BCM into my system. ESS is not working too.

I think it is safe to conclude, M3 is different to CX-5 in ESS.

peace

Hi everyone,

I try to enable TPMS on my car Mazda3 (VIN: RN2BN4AA6HC066516)

And I input some value by Forscan below:

Original: 720-01-01 2A00 7226 806B
Modified: 720-01-01 2D00 7226 806E (with Region code B0 b3b2b1b0 = 1101)
Modified: 720-04-13 0000 0007 BF04
Modified: 720-04-01 19DD 0008 FFA1

After do that I got result: TPMS light ON but DSC and ABS warning light ON at the same time and i-stop (amber) blinking
and DTC U2300:52-2B Central Configuration

I tried to reset DTC and caliberate all item. Here are result:
1. Lateral Acceleration sensor: OK can do
2. Pressure sensor: OK can do
3. Tire Pressure Monitoring System: FAILED to cablirate
4. Longitudinal Acceleration sensor: OK can do
5. Yaw rate sensor: OK can do
6. Module reset: OK can do

With above things DTC still there. Please help me point out what wrong and what I need to do more?

I read a lot of pages and tried to find answer by my own but I could not. That why I need your help to do. Thank you so much for your time.

what if your car dont come with the TPMC hardware?

 

[hahaaha]

Mazda takes TPMS info from ABS wheel sensors, so no extra hardware (except new CX5)

I'm still able to actived TPMS on my CX5 2017 (its 2018 in some countries) without any extra hardware, just change value from excel's refer.

So how it works without the reset button on dash button?

Assuming the tyre pressure is calculated by using ABS rather then direct tyre type, the warning will go by itself when air pressure for all 4 wheels are equal?

 

[hahaaha]

Without the button you will need to calibrate using forscan after setting the tire pressure and then drive for 15 mins. If the light goes on, it means the wheel speed sensor has detected one or all tires are outside of a tolerance of 15-20% meaning 1-4 tires are low or all tires are high.

You will need to calibrate after the initial if you do a tire rotation or if you get new tires or it will give a false positive.

oh, which means i can only calibrate once n need to calibrate tru forscan again when i want to readjust my tire pressure for my drive for different situation.

 

[hahaaha]

A little help please.

Can anyone supply me your ABS as-buildt with TPMS included in your car?

 

[hahaaha]

ABS has a module with data?

Yes i did. With Forscan 2.3.15 Beta

It falls under 760-03-01. Only 1 chain with B0 and checksum.

 

[hahaaha]

You're welcome. I spent many hours to study, try and learn to get to active LAS, LDWS and HBC on my M3.

What if I want to activate HBC but not LDWS?

Is it possible?

 

[hahaaha]

Good evening everyone.
As Nikodim advised me, I changed the lines in the FSC for such.
;Block 1
70601012120513000D1
70601026C82000000FE
7060103000000000011
7060104000012
;Block 2
70602016C82000000FE
7060202000000000011
7060203000012

True, this did not fix anything. There was still a dashboard error.
Then I changed bytes b7-b4 in 720-04-19 and restarted the car a couple of times - and lo and behold! All errors disappeared. In the instrument panel lost menu SBS system.
IC 7200419200000100074

But I also noticed an interesting thing. I launched a real-time readout of parameters from the FSC camera. And performed a series of actions - pressed the brake pedal, turned on and off the high beam headlights, etc. Everything was reflected in the parameters of the camera signals. This means that the camera sees the rest of the car on the CAN-bus and this is good.

The only thing that the camera signals did not change at all is the data on the LDWS system. But I think the point here is that I do not yet have the physical buttons for turning this system on and off. And I think because of this, the system is not working right now. The buttons will arrive literally within 3-5 days ... I will install it and check it out.

about the LDWS SW, it is always off.

infact, only when u are pressing it, it will switch to "ON".

even when your LDWS is activating, the SW still showing "OFF".

it is merely showing you are either pressing, or unpress the switch. nothing more nothing less.
