sigma 30 alarm- immobiliser schematics


Recommended Posts

2003 Forester.

 

Been having bad electrical/electronics gremlins lately. I may have narrowed it down to knackered alternator and badly fluctuating Battery voltage(as low as 9v..) but I also suspect the alarm. The alarm can be taken out of the loop but in doing so,it defaults the immobiliser circuits on. Does any one know which pins on the multi-plug on the sigma are the  two circuits and can they be just joined together to enable the ecu to allow the two circuits to function again. I suspect that Thatcham specify unrecognisable colour coding for the circuits which is a nightmare if problems occur.

 

Any suggestions ?
