Weak battery cause srs fault?

IRONHEAD1975 · Mar 14th, 2018, 09:55

so Iv gone through crash data had my module repaired,it went faulty on a frosty morning in the beginning since crash data repaired it no problem until another frost this morning and it's back arrgghhhhh two weeks or so it lasted.when I start my car the interior and info display flickers it seems as if the battery is a tad weak nowadays does anyone know if this would trigger a srs light I'm hoping to replace battery and send module back to crash data cheers

I have emailed crash data too see if they can confirm that a weak battery would cause the fault again.they have replied in a few mins to confirm my suspicions that the battery is the probably the cause especially because it's happenI got on frosty mornings when the battery is weaker they confirm weak battery can cause the srs warning hope this helps anyone else with the same issue 👍🏻🍺

A weak battery can cause the SRS light to linger a bit longer than usual on the dash. It should extinguish after a short period of time (usually less than 15 seconds) even with a weak battery with the engine running. If it stays on, it points to a fault within the SRS or charging system.

If the alternator fails and stops charging (almost inevitable at some point post 100k miles on 4 cyl diesels) - the first indication of the voltage getting low is usually the SRS warning.

Just seen your signature - you have the D5 which has a Volvo spec alternator not the Ford rubbish fitted to 4 cylinder diesels so its likely to be fine. I would get the battery checked though.

Ive just had my airbag module returned from crash data and they put a sticker on mine saying cfff error is caused by a low battery voltage so just changed the battery to all seems fine now

It's a shame mine never came with that sticker on the bottom,I'm off to pick up my new battery today from Volvo £90 plus vat and I await the arrival of my module tomorrow I hope this will be the end of the red triangle for good 😎🍺
