Hi. Looking for advice on what to do next following ecu faults i found this evening. Stored faults are as follows: Battery voltage v to low Injection left Injection right 0V Main relay 0V New Fault Injection left 12V Battery is good. Tried swapping underseat relays no difference Thanks
Depending what you’re using for the diagnosis typically if they’re marked as stored faults it means they’ve happened in the past, are not current faults, but they have not been cleared out of the ecu. I’d guess that historically the battery had an issue and wasn’t supplying the correct voltage. I’d delete the faults, re interrogate the ecu and see what, if any, current faults you have.
This ^^^ Would recommend, at the very least, running the engine between clearing and re-checking. If not going for a short ride. Some faults might not manifest themselves until you do this.
Thank you both for the reply. Fault has now been pin pointed to no power on the horizontal fuel injector connector
