Question about 2005 Subaru Legacy
Can be a temporary fluke - disconnect battery and press brake for half a
minute to drain everything and then reconnect battery and see if it
still is there. It may also be that the battery is going down the drain causing the
voltage to get too low for the electronics to be reliable.
The no E/T issue is a known defect on '05/'06 trip computers. I believe there was a TSB (tech. service bulletin) issued and it was a warranty fix.
From other Subaru's Owners...
Quote: My 2006 Outback has something draining the battery when it sits. About 4 months ago I was having weird electrical issues with the speedometer and the odometer was flashing an SP ER message and the time/temp display would flash "ACC" then change to Err. The dealer replaced the battery. The ACC flashing was still there but the car seemed to function fine. Now the battery is draining when it sits and the car needs to be jumped after sitting a while or if driven for only a short trip. The dealer now says they don't know what the problem is. I do have an after market remote start but that has been in the car for more than 2 years. Does anyone know what the "ACC, Err" flashing display means.
It sounds to me like you have a short somewhere. SP ER means the speed sensor is either not working or is providing bogus input. I suspect that the display is probably having trouble as well due to the MPG readout, etc., that is tied in to the speed sensor circuit.
It might be useful to check the wiring on the aftermarket remote start to ensure that there are no loose/corroded connections. Just because it worked properly to start, does not mean something has not come loose since then.
Hope this help.

For a long shot. Make sure your battery is putting out a full 12 volts. If your battery is old maybe a new battery will due. Some Chevrolet cars display will go nuts if the voltage is low they require a full 12 volts. I hope this does it for you.
