C4 CACTUS LIN Fault & Cruise control dropping out

[EdMar]

Hi

I'm new to the forum,

I recent got a C4 Cactus with a niggling code.

Bsi U1F1B LIN Fault 21 is the most persistant code.

I'm no longer able to access servicebox after stellantis take over (no VAT number)

Could I possible request some wiring diagrams ?

Mainly LIN BUS relating to U1F1B code, BSI terminals ,
VIN : VF7**************[VIN obfuscated, can be read by forum staff] , sorry forgot to get production number
If possible would also like, Telematics Terminals. TouchScreen
Multimedia CAN.

Cruise control drops out occasionally, Vehicle speed signal code (didn't log number),
There is a worn suspension bus my be affecting ESP / Cruise.

ESP light not on when cruise drops out, also ESP off button not responding

Also U1F3E Absence of telematics comms, & U1F18 Touch screen not communicating on multimedia CAN.

Also on one start, no audio from radio was observed.

I am thinking a data comm problem in the BSI/Telematics/Touchscreen area

Is touch screen comms a requirement for Cruise control function ?

Thanks in advance

Hi,

I'm a bit further on with this,

Santa brought me a nice handheld scope fast enough to check CAN

There are issues with CAN network, think I know what it is

I will post more if I manage to confirm.

Wiring diagrams would help pls.

Hi, sorry but I don't have any wiring diagrams for the Cactus, and we don't provide technical docs / wiring diagrams unless staff already have them.

Any issue with the ESP system and cruise control and any associated features like Hill Start Assist, descent control and such will be deactivated.

Hi

Yes I am thinking that it is a message from an ESP related component possibly on a LIN BUS connection , that is not getting through to the ABS due to noisy CAN.

ESP button linked to BSi by LIN?

Codes can be misleading some times,
With out having the scenario which triggers the code, Hyundai manuals descibe what sets the code, but most codes range from lost in translation to down right obscure.

I'm thinking the code meaning may be closer
'Message from LIN connected component not reaching destination'

Noisy can not letting low priority button message though, is my working theory at the momemt.

Been prodding ESP button every few minuites & fails about 5% of the time.

Hope do a bit of reverse engineering on the CAN next week.

Hi,

Could I request the build sheet pls?

Also a parts look up , if convenient,
If there an ABS loom listed for cactus

Similar to this ebay one for C4

As far as the harness is concerned, there's no separate electrical harness for the ESP system (apart from the wheel speed sensors of course). It is integrated into the main wiring harness:

Hi,

Thakyou,
Build sheet informative ,
Manual fold mirrors,
they are stuck & i didnt wasnt to 'encourage' them too much incase they were power fold (some power fold need taken apart to free them)

Standard power windows,
That explains why I cant reprogram the Auto-windows

Is there a thread for requesting build sheets , radio codes etc ?

I used to use servicebox and other manufacturer sites,(before new stellantis system req VAT no.)
and i do a bit of diagnostic work for mates in the trade, so often forum donations are worth the time saving (previously would have jumped on servicebox etc which were chargable)

Borrowed a picoscope & quick decode of can bus, showing low priority packets getting dropped, mate says PSA cars with ABS in wheel arch prone to water ingress & any time he has arch liner out, clutch etc, he checks ABS plug, contact cleaner spray & electrical grease.

Thanks again

Pop up any parts only requests on the Official Parts Thread to help ensure your request is not missed. Ask for a build sheet as needed, (please bear in mind this isn't intended for commercial use), but we don't mind the occasional request.

Just for reference: PSA vehicles don't need radio codes - the Head Units are all VIN-coded to the vehicle.

[EdMar]

Hi ,

Thanks, I was thinking Renault for radio codes, but I think newer ones are VIN coded to.

I get a few diagnostic jobs from mates in the trade, sevicebox etc wanting VAT is may the push I need to go into it in a bigger way.
In the mean time if I have any commercial related requests, I'll make the odd extra donation .

Thanks

No worries - it's the time more than anything as we have hundreds of posts to get through on the Forum each day. Staff can't provide any official technical help for Renault as they have a different system, so staff can only help with part numbers and part diagrams for Citroen, DS Autos and Peugeot.

Renault should also use VIN coding this day and age for their telematics units too.
