| FBH Controller - BAS - Question |
|
Hi All,
My FBH is one of the odd ones that has been working fine (when the temperature drops and fuel etc. is correct  ) its fires and warms up nicely and so via the forum I procured a BAS controller so I can start it by flashing the lights. - I will be getting a newer one soon which has an interface to the FBH as well but I was impatient 
Just fitted it this morning - nice and straightforward but I have a question.
It doesn't seem to work 
This module is the 'flash the lights' type.
The module is flashing its green light every 15 secs (which I think means its initialised, talked to the FBH and is in standby mode, ie normal).
I flash the lights as detailed - tried different timings but as per suggestion 5 secs on is what I settled on then off.
I expected it to fire up - but nothing happened
I've check that the wiring is correct - it is.
Ive checked that when I flash the lights I get +13.5 volts on the right lead to the box from the lights, the black wire is connected to the post on the wing, its got +13.5 volts on the red wire and the fuse is intact, and the wire is connected to pin 2 of the correct FBH plug.
I've checked the FBH with my forum wiring lead and the webasto software and it functions correctly and there were / are no faults recorded.
So - after all that context - my question is - if the outside temp is too warm for the FBH to fire normally (6 Deg I think) will the unit not function ?
ie if the FBH wouldn't work in normal circumstances because its too warm means that I cant start it manually by flashing the lights ?
Would explain it I think - perhaps I will have to wait until its colder to test ?
Ohh and there is plenty of fuel in it 3/4 of a tank.
Any ideas - or is it as simple as its too warm

when you flash your lights does the fbh try to start? what does the led on the box do
they can take a bit of time to decide to start its not instant when you flash the lights,outside temp doesn't matter but if the engine is up to temp it wont fire up
also are you just flashing the lights with the stalk switch or have you programed the 3rd button on the remote to flash the coming home lights,i think the car needs the doors closed to work ignition off also (cant remember) mine was a bit tempremental when I first fitted it (have a plip on mine) very reluctant to start if you battery shows 12.2 or less which most cars do if they are not locked up and "asleep " please excuse any grammer/punctuation mistakes,i'm thick,thankyou

Hi,
Thanks for the response
The FBH doesn't do seem to do anything or try to do anything......
The little green light just flashes every 15 secs, which I think (from reading on the forum) means its initialised and waiting for a 'flash' but I may be wrong!
The green light doesn't change or do anything when I give it the 'flash' just flashes every 15 secs.
I thought I gave it plenty of time to do something but maybe I was impatient!
The car was cold (ie I hadn't started it this morning), although the outside temp was +8
Its programmed for follow me home so I'm using the 'third button' to flash the lights, and that works fine - not using the stalk
My only guess is that the pin 2 connection can't be quite 'home' in the socket or something like that on the FBH - but it the unit appears to initialise correctly (ie its flashing every 15 secs) - although what should it do when it initialises ? - what flashes should it do on the unit ? - i'm fairly sure ( ) that I saw it flash twice quite close together - but I might be wrong - is that correct ?
Anyway I'll have another look in the morning - especially around the pin 2 connection to the FBH as without that it wont talk to it from what I understand.

13.5v is too high. Is the engine running or you have a battery charger connected?
It will think the engine is running so won't control it.
When you get the lights on for 5 seconds And switch off, does the BAS unit show anything different on the led. It should change when trying to fire up. Bodsys Brake Bible

Hi,
Thanks, I've both a reader and the webasto software and harness from the forum, and the FBH is fine and dandy (as per my rather long first post!!) - so its not locked out or showing any errors.
I'll have a another look in the morning, probably something stupid that I've done  
Thanks for you suggestions

Hi,
right, I've now checked again, and can confirm that the wiring is correct, pin 2 is connected to the FBH via the green wire
I've disconnected the power to the unit, left it for 10 mins, reconnected it after settling down its blinks it green light twice, and then settles down to a 15 sec (approx) blink of green.
I've also now connected the blue wire (the one going to the headlight) directly to the battery for 5 secs to try and trigger it (after disconnecting it from the headlamp !)
And......
Nothing it still sits there and blinks the green light at me every 15 secs.
I've again checked the FBH - no errors recorded and it passes all its checks through the webasto software, functions as expected.
I'm at a loss now - any ideas that I've not tried ? 
Thanks

try closing the bonnet latch on drivers side with a screwdriver then lock up the car wait 10 mins for it to go to sleep then try powering up the blue wire for 3secs on the battery (leave bonnet up when closing latch on drivers side) see if that works please excuse any grammer/punctuation mistakes,i'm thick,thankyou

I think you'll find it's just too warm today - force fired mine with Webasto diags today (long story  ) but whilst getting it ready noticed the cooling temp was 12c

The remote will fire up the fbh whatever the ambient temperature Mark.

What voltage is the battery actually at? The above cannot be true with the engine off unless you have a charger or similar connected.
Disconnect it if you do. Bodsys Brake Bible

Hi,
Apologies for any confusion - I used generic voltages to describe whats happening.
So.......
This morning -
Voltage 12.35v (immediately after going to the car, not starting or running just open the door and open the bonnet.
I do use a Ctek but this was disconnected.
And exactly the same thing - nothing, flash the lights using follow me home third button for 5 seconds.
The BAS unit sits and flashes its green light to me every 15 seconds.
I've now got an IID BT and so used that to check any faults - none found (on the whole vehicle ).
tried with bonnet open, bonnet closed, car un-locked, car locked.
any ideas ?
Ohh and in the cold weather yesterday - the FBH started and ran perfectly - warming up to half scale when driving in the 'usual' manner.
I've checked the cable to pin 2 again, correctly located and inserted as far as I can tell - ive checked physically and i'm assuming the unit wouldn't flash every 15 secs if no comms was taking place - but i may be wrong?)
Starting to worry that the second hand unit is faulty
I'm stumped
I've a very well equipped electronic test bench (dont ask!!) and so I could have a look and see if the unit is trying to talk to the FBH on the test bench using a scope as I'm coming to the conclusion that its simply not asking the FBH to start up.

Assuming the unit is a real head light flash unit and NOT a older version someone other than me has just added a wire to the pcb which will never work..
Pin 2 is not the problem as if it was the unit would not flash green every 15 seconds as you say....
Remove the BLUE wire from the head light totally, with the green led on the main unit flashing 1x every 15 seconds hold the blue wire to the battery + for 5 seconds then let go. This should trigger the heater.
If it does not then something else is wrong. But as said if voltage to high it will not trigger it.
