When Alternator is faulty or undercharging battery, the entire injection and ignition components will start malfunctioning because they are receiving less voltage to run properly, including the gadgets like AC, radio,etc, that will start going off or won't run well.

Likewise, I believe same applies to low amp fuse supplying power to a system to requires higher amp. The fuse could get blown, depending on how low the amp is when supplying a system or components that needed higher. Its only logical anyway.

The thing is, 206 owners manual says those Maxi fuses on your BSM ABS slots should be 60 A, but yours have 20 on each. Maybe the 20 A fuses on those slots came as factory, maybe not.

The point is my fuse dint blow and my abs is malfunctioning could it has been the fuse that has given me problem

Becuz it dint blow so i would say that it is probably a stock 20A fuse and i fear that if i put in a 60/30A fuse in it might short out my electronics

My alternator is good by the way, giving me good voltage and its new

just want to ask something

as you can see from previous post, i have a abs issue

my Maxi Fuse for the abs unit is lower that the ratings in the internet but it didn't blow out

will a lower rating fuse(20amp fuse in a 30 amp slot) by any chance cause problem to the abs when the fuse is not blown?

Ikenna, My problem has not been solved is there anything i can do?

Ikenna351:
Ok.

Pull out the BSM from that box. You will find the Maxi fuses under the fuse box, on the side where the battery cable is bolted on the fuse box on top.

Ikenna, The Lion King.

So i look at the maxi fuse this is the picture that i have obtained

i dont see what you have described that is Maxi Fuse 2 60 A and Maxi fuse 3 is 30A , i have both maxi fuse 2 and 3 at 20A

when doing some research i say some ebay BSM seller also have maxi fuse 2 and 3 have 20A

what do you reckon?

Ikenna351:
Could you take picture of the BSM in your lion and attach it here?

here's the photos

i dont know where to find the maxi fuse on my peugeot 206 RHD
BSM fuse 3 is a 10 amp fuse

here are the videos for reference

Ikenna351:
The last live test I did on a CAN-bus lion ABS (407), I got 13-15 volts while in motion.

Anyway, the swap test you did ruled out the connection, ABS pump/ECU as the culprit. So what left are the sensors and reluctor rings.

To rule out the sensors, you need to test those sensors on another 206, if possible, one with multiplexing electrics (Besides most phase II 206 have ABS, unlike the phase 1). You will need to find a drivable 206 at a workshop that you can swap in your rear ABS sensors, drive and check the readings while in motion. It has to be 206 that the ABS works. Quite challenging, but it will help narrow it down for you.

Ikenna, the Lion King

i Think i can say that there is no problem with the sensor and distance of ring because as said in last post, i can read the sensors reading accurate when the car is not running(ign on only), it only stops working the car is started.

not that i dont want to try using a drivable sensor, but in my country, 206 with rear disc are RARE, mostly are rear drums, that is what car manufacturer sell. My model is imported so it really is hard to find such sensor Anywhere, Sorry.

What do you suggest?

Ikenna351:
Usually, a weak or failing ABS wheel sensor would sense the rotation of wheel, but at less speed than the other wheel report. They most times give 0km/h when the ring reluctor is absent or teeth covered, broken or rusted out.

It starts first by reporting intermittent fault before changing to permanent fault, unless the sensor is damaged or wire broken.

Question now is, are you really sure the sensor is very close enough to the reluctor ring to sense its rotation? This was the reason I asked if the axle was exactly same type for the cub that was removed. Otherwise, I would suggest you get a used ABS rear sensor and swapped in and see if it signals vehicle speed, to rule out the new sensors.

Ikenna, the Lion King

So i took you advise and do some swapping and wire tapping
I found that when i connect the front wiring to the rear abs sensor it was not sensing anything and when i connected the front abs sensor to the rear wiring and i got thw signal so that it means my rear wiring are fine and that my reluctor ring or abs sensor is faulty or even maybe the distance between the ring and sensor is wrong , what do you suggest i check now?
I assume its the distance of the ring but how i fix that?

***NEW: i finally found something that is making sense of all this, so i now tested it when the car was not started, jacked up the car spin the wheels and it shows data on the diagnostics tool. SO, the problem would be STARTING the car, i assume that it over-voltage that is causing this problem but i am not sure if it is caused by over-voltage, my voltage to ABS control unit is 16-17 Volts, While when the car is Started and running the diagnostics show that my Voltage to control unit is 20.2 Volts , i wonder if this is normal. and this problem sync with a minor problem that is already had for some time that is the fuel pump gauge is not measuring well when the car is started and running( when i used the diag tool i see 3 Readings that is FUEL LEVEL MEASURED. AVERAGE FUEL LEVEL AND FUEL LEVEL DISPLAYED. when the car is NOT started the readings of FUEL LEVEL MEASURED is fine but when the car is started the FUEL LEVEL MEASURES spike up another 15 liters or so causing my speedometer to show an incorrect fuel level , i think this is related , what do you think caused this problem.

Thank you in advance, hope to receive your reply soon.

Ikenna, the Lion King

my old sensor din't work out so i change to a new one.

to answer your question that if the sensor are close enough to the reluctor ring to be sensing speed?
- when i did a alternative current test on the sensor it does increase when i spin the wheel faster so i do assume the sensor is sensing the ring and is working fine.

Ikenna351:
I was referring to the sensor connectors, that is, if the rear sensor wires would be long enough to come to the front. But from the images you posted, the connectors look different.

Any form of braking issue in 206 with CAN-bus will give the STOP warning sign, even if its faulty handbrake switch.

Ikenna, the Lion King

i will try to make that happen maybe get a long wire to connect the pins. but in the meantime i really have to figure out what went wrong.

i was unable to accept the fact that the system could sense if the sensor were open circuit but not sense the speed.( when i removed the sensors, i would get a permanent fault that is open circuit or short circuit, but when i plug in the sensors i would always get coherence.)

Ikenna351:
Since both are multiplexing / CAN-bus, the connections to the BSM would be the same.

However, BSI unit in Multiplexing Lions uses ABS wheel sensors signals to interpret and controls the speedometer (most of them). If that is the case, you should get intermittent fail on Vehicle speed sensor on BSI unit fail reading.

Try this. Can you swap the connectors of the wheels sensors (front to rear and rear to front)? Even if you connect only one rear wheel sensor to front wheel connector from ABS pump side and disconnect the rest. Then do another parameter measurement while in motion and see if the km changes on the front wheel while connected to the rear wheel?

Ikenna, the Lion King

Front and rear abs sensor are not the same so swapping wouldn't be an option , sorry

by the way, When interpreting with PP2000 i only get one permanent fault that is coherence rear abs sensor

any other ways i can work this out? i have tried many was to make it work but i am already about to give up and just gonna live without ABS, i can live without ABS but i cant live with the dash light shining STOP * STOP * STOP * all the time when i'm driving.

***INFO: when my speedo speed is 50 KPH, my abs sensor speed would only be 25 KPH it does increase according to speed but not actual speed, althought i suppose that if four sensors are sending data the abs system would still work because they are the same speed ***

Ikenna351:
When you removed TU3 engine and mounted TU5, were both injection system using Motorized Throttle Body? If not, it means you swapped the engine wiring harness? Was the 1.6 litre engine TU5JP or TU5JP4? If you swapped the wiring harness, were both (donor and current Lions) Non-multiplexing or full multiplexing?

When did you observe the ABS ECU stopped receiving feedback from the rear wheels? Immediately after you swapped the engine or replace the rear axle?

Have you confirmed if the Peugeot part numbers of 5-door 206 Rear Right & Left ABS wheel sensors are the same with 3-door 206 cc? Did you replace with exact rear axle?

If you swapped in a TU5 engine wiring harness, then you swapped in the BSI kit, right? VAN-bus BSI unit and CAN-bus BSI unit are not the same, same as the car electrical connections, etc.

If those rings on the wheels are intact and the new good ABS sensors are mounted close enough to sense the rings and the connection between the Wheel sensors to the ABS pump/module are in tact, with the right wiring & control modules, then the ABS ECU should receive live signals from the rear wheel sensors as the wheel rotates.

But the first question to answer is, when did you observe the ABS issue? That will answer the rest of the questions I asked above and get the issue resolved.

Ikenna, the Lion King

If you dont mind i can tell you the details of what i have done since day one.

My old TU3 's gearbox went dead so i decided to just buy an halfcut TU5 to replace the whole thing since its just the same price
I gave my car to a mechanic to swap out everything

To answer your question
- i have swapped the BSI ,engine ECU, wiring ABS pump , And most wiring except internel wiring becuz some electrical system are not same such as the rear wiper washer and such
-the problem went out the first day i got the car because it was a halfcut and was left off for few year unused so we would expect it to have some issues at first but all lights went off except the abs light.
-both are full multiplexing as i would expect becuz donor car was an 2003 and original was a year 2006
-i couldnt give an exact answer whether the axle was the same one because it was give by the dealer but i assume it was the right one
Things i have done:
-buy new sensor and replace, same with what was on the axle before that
-problem was not solved so i check the reluctor ring and cleaned it (no dents ,no chips, no crack, just bright shining metal.)
-then i check the wiring to know that if there was any broken wire in the middle but was fine checked connectivity from the abs pump connector and also checked if the was AC(alternating current)~~ power to the abs pump connector, wiring seems fine.
Thats all i can give
Thans for you concern and i look forward to receive you reply.

***EDIT: you mention that VAN-BUS /CAN-BUS problem so i went on and look out for the car's BSM and found that the BSM unit was my original unit not the donor's any chance this might has caused the problem?***

IKenna

wonder if anyone can help me with my Peugeot 206

to keep it simple

I have an old peugeot 206 1.4, fitted with a 1.6 engine from 206cc, fitted with new axle too

now i am having abs problem

Rear right and left coherence, live data shows 0 kph.

What i have done:
- Check wire Harness-OK( Good from abs sensor to abs pump)
- Change New ABS Sensors -DONE
- reluctor Ring- Checked( looks New)
