Old thread but rates high on a google search, so relevant replying here I think. Thanks for the info, I had the same set of lights come up and only realised the battery wasn't charging when the car died. Not far from home, I was able to pull the battery, take it home, recharge it, then I was able to get the vehicle back home. I noted the telltale voltage drop on a multimeter after starting the vehicle. I'm going to try my own repair on this unit as it isn't the main driver, I'll report back on my findings.
I don't know the correlation, but I sat through Marcia in Yeppoon and after losing power I used a little 150w inverter to charge phones and drive the solar hot water pump. I periodically took the vehicle for a drive to charge it back up, and on the second day or so I think, I got the dash lights. So... I don't really know the cause, whether having the inverter on when I started the car caused some kind of back surge or if the very low battery charge overloaded the alternator, or if it was just some big coincidence that something was ready to go anyway. Also, I have a DTDAuto diagnostic unit which is capable of picking up OBD1 fault codes, it came back with no reported faults, so it seems it's only reported on the dash lights.
