Thread: ValeoTD5 Lockout and immobilisation

have a look at the settings/info on this link.
have a good look at it, it tells you what the settings will do, you can go through & check/change the settings to your preference with your new toy...

https://www.blackbox-solutions.com/shop/help/SM023.html

Also have a look in RAVE under the Alarm System and Horn and BCU sections.
The Description and Operation in each section has detailed information about all the settings.
If you read RAVE in conjunction with the document that roverv8 linked to you'll know pretty much all there is to know about those BCU settings.

Thanks for the info from roverV8 and OffTrack.
That's very helpful for when I get that far.
I only had time to hook up the Nanoscan for a quick test. It found two engine faults - EGR Open and Air flow to the engine. I haven't looked it up yet but the airflow one looks like it's input manifold flow but that's only a guess. The EGR Open I'm not too worried about.

However a SLABS test showed "No Faults". I wish that wasn't the case. I was hoping it would tell me there was a fault in the BCU or the in roof receiver or something else useful.

Why the TD5 immobilizes at what seem to be random stops and exits. I get out, open the tailgate to let the dog out and down she goes, before I've even tried to lock it with the key. From then on she will not respond to the fob or the EKU.
However it's logical that as long as the key is in the Accessory position it never seems to immobilise.
I'll next download a map of the SLABS area and look for abnormalities.
Just one point though: I enabled 'Transport' mode via Nanocom and she did the same thing as before at the next stop - immobilize.
Never responds to either key, both with new batteries but after she's been left overnight she will respond to the same keys.
I love the old TD5 but she's driving me to very bad moods.
I'd be very open to suggestions as to where you think the problem is.

Passive immobilizer:
The BCU immobilizes the engine 5 minutes after the ignition has been switched off, providing the drivers door is not opened. The BCU will immobilize the engine 30 seconds after it detects the driver's door opening.

worth a shot to make sure this is not enabled, can't hurt to try

SLABS is the Self Leveling Suspension and Anti-Lock Braking System. Nothing to do with the alarm or locking.

Everything alarm related can be found in the BCU module.
The SLS fob raise and lower is handled by the BCU which passes on control signals to the SLABS ECU.

I'd strongly advise leaving the transport mode settings alone, and disabled. We have had reports on the forum of people putting the SLABS module into transport mode and then having huge problems restoring normal function. You have been warned!!

The ECU's are computer systems and are inherently logic based. They need to be approached with a calm head and a methodical approach to sorting the issues.

Are you able to save out the current BCU settings to file and then post up the settings file? It might help have someone cast an eye over the current config.

As a reference this is my BCU config. Not to everyones tastes or requirements I'm sure but might give you an idea of what the alarm options need to be set to.

Code:

NANOCOM - VALBCU.APP - VALEO BCU setting file

param;value
Front fog lamp;NONE
Daytime run lights;NONE
Courtesy head lamps;ENABLED
Headlamp power wash;FITTED
Electric front window;DRV CANCEL
Rear windows sunroof;DRV CANCEL
Heated front screen;NOT FITTED
Electric front seats;NOT FITTED
Programmed wash wipe;NORMAL
Seat belt warning;BUCKLED
Seat belt warning sound;DISABLE
Autographics;SIDELIGHTS
Transmission;AUTO
Shift Interlock;NONE
HDC;FITTED
Superlock;SINGLE
Single point entry;SPE
Speed lock option;ENABLED
Mislock option;ENABLED
Bathrobe lock option;DISABLED
Odometer error warn;FITTED

Low battery warning;ENABLED

Transmission;AUTOMATIC
Engine;DIESEL
ACE;YES
SLS;NO
Gulf;NO
Police;NO
HDC;YES
TRC;YES
Alarm;FITTED
Alarm option;ENABLE
Alarm disarm;ALWAYS
Alarm sounder;ALL
Alarm tamper;ENABLED
Engine immobil.;LED FLASH
Passive immobil.;ENABLED
Inertia switch;HAZARDS

Volumetric sensor;FITTED
Market;AUSTRALIA
EKA option;ENABLED
Cruise control;FITTED
Air conditioning;FITTED
Fuel burning heater;NOT FITTED
Passive coil;FITTED
Transit mode;NOT SET

And don't forget to check ALL the settings before writing. As has been mention before it quite common for settings to be changed without user intervention. The Transmission -> TRC page is the one that seems to get clobbered, so you end up with Petrol, Manual and NO to ACE, SLS, HDC, TRS which is generally not what you want.

I know what SLABS does. I have had older SLABS issues as well. The reasons I was looking at SLABS was because I had previously had Air Spring and subsequent air compressor failure. Because I knew where these occurred I wanted to see the fault message warning to get used to what I expect to see. There weren't any and now I've figured why. The previous mechanic who fiddled with my three amigos warning lights would have cleared them.

It's true that in the quick 10 mins I had the Evo connected before dark, I'd not found the Valeo BCU menu. I have now.
The warning about the Transport setting is noted. Several English websites featured problems similar to mine and the Transport mode solved it but left the security vulnerable. I'll disable Transport as it didn't solve my problem.

Your warning about computer systems is noted: I understand computer systems. I spent 30 years as a professional Electrical and Mechanical engineer working in vehicle building R&D (not on Landys), but the last 25 years have been spent as a software developer - however it's taken me all those years of fixing my own broken cars to realize that I'm a bugger of a mechanic. I understand all the complex systems but my implementations are appalling.

Your suggestion of uploading the BCU menus is a good one so you and others can help spot abnormalities. I would be most grateful.

It will take me a few days to do that because my wife takes the TD5 to work and leaves the key in accessory position so she doesn't have to walk the 9 km to home and she doesn't return until dark. As well, I presently have a stinker of a bad back and I set it off again by groping around under the fuse panel for the OBD plug last night. I'll come back with the settings when I have them.

Thank you for taking the trouble.

Tony,

A lot of O/S (UK and SA in particular) forums seem to equate disabled with fixed but never bother finding out what is actually causing the issue. I guess that will work up to a point, but eventually you run out of things to disable

There are a limited number of settings in the BCU and/or SLABS that could cause the kind of issues you are having in and of themselves.

SLABS should be set to:

Test Status: Enabled
Transport Mode: Disabled
ECU Calibrated: Yes
Suspension: Air/Coil depending on vehicle config.
Left Stored Height: set if SLS
Right Store Height: set if SLS

If that is correct you should be fine. Faults can't be rectified by changing these settings, so once they are right you can basically leave them alone.

In the BCU the follow are the things that should be set:

Transmission;AUTO (set to match vehicle)
HDC;FITTED

Superlock;SINGLE (read up on options in RAVE and set as desired)
Single point entry;SPE (ditto)
Speed lock option;ENABLED (ditto)
Mislock option;ENABLED
Bathrobe lock option;DISABLED
Odometer error warn;FITTED
Key warning;DISABLED
Low battery warning;ENABLED
Bulb failure;ENABLED
Transmission;AUTOMATIC (set to vehicle spec)
Engine;DIESEL (set to vehicle spec)
ACE;YES (set to vehicle spec)
SLS;NO (set to vehicle spec)
Gulf;NO (always no for Aus)
Police;NO (ditto)
HDC;YES (always yes)
TRC;YES (traction control, always yes)
Alarm;FITTED
Alarm option;ENABLE
Alarm disarm;ALWAYS
Alarm sounder;ALL
Alarm tamper;ENABLED
Engine immobil.;LED FLASH
Passive immobil.;ENABLED
Inertia switch;HAZARDS
Hazard option;ALL
Volumetric sensor;FITTED (dependent on vehicle)
Market;AUSTRALIA

Passive coil;FITTED
Transit mode;NOT SET

Again providing the setting reflect the vehicle config and nothing is obviously wrong there isn't much to be gained by playing with settings.

The nagging doubt I have is that the problems seem to be more random than can simply be explained by changed//messed settings. Do you know if the mechanic that attempted to fix the amigos made any changes to the wiring in doing so?

Anyway if we can establish the ECU settings are correct, then we can look at what else might be causing the issues.

cheers
Paul
