Alarm malfunction -maintenance required
Hi all,
Volvo s60 2014 D4 181hp business edition Quick question on this error code: I noticed my stop/start was not working just before this error code appeared, does anyone know from which battery the alarm backup batteries inside the alarm sensor diode charge from? I presume if I charge the main battery, it will charge the support battery and in turn the alarm system (if working ok)? Or am I just going to have to replace the alarm siren unit? |

The alarm batteries are a couple of AAA NiMH batteries of the type you find in a cordless phone. The main car batteries would have to be virtually completely dead for them not to provide any charge.
The alarm batteries tend to fail/corrode after 6 years or so, see the other thread on here for fixing suggestions.
