Hi,, just replaced the battery (engine) in my Burstner a class motorhome, built on an 05 2.8jtd and when first switched on after reconnect, I get ABS light and handbrake light. Tried a short drive, never got to 10mph due to no room, and several swith on/off cycles. No change. Any thoughts- this fault was never there before the battery was replaced. Should it be necessary to plug a laptop in, what do I need? IIRC I have fiat ecuscan somewhere, but what about leads? I have an ELM 327 (may not do abs??), or a generic bluetooth OBD reader. I also have a vgcomm which I suppose is useless for fiats. If I need something, what should I get? All help welcome!

Hi, did you ever manage to solve this? I’ve just changed my Ducato battery and now have the same issue!

Many thanks

Ian.

Hi,, it ended up going to Fiat who did sort it, they implied it was an earth issue (which I do actually think it was now), but when questioned further, they did not elaborate. I would suggest checking all earth cables- main ones between engine and body, also check all plugs and connectors between the ECU, ABS unit, and cleanliness of battery terminals and associated fuseboard thereon. Also connections to underbonnet fuse panel, and look inside that for signs of corrosion. TBF it has been OK ever since. I fitted a good quality battery (IIRC a Varta) but these vans with the non full canbus setup, don't like too low of a battery voltage. Not as bad as the later ones maybe, but even so, keep an eye on it.
