moviemadness Posted February 13, 2007 Share Posted February 13, 2007 Ok, first thing's first my car won't start!!! The battery is not dead cuz everything else works. When I turn the ignition all the way on, all I get is the beeping, the gauges sweeping, but no ignition! All I get is Err HC on the mileage gauge. Does anyone know what this means? Did I really screw up bad?? Ok well here's exactly what happened. After flashing the ECU with Cobb stg. 1, everything was fine. Then I the firmware update came out, so I followed these directions. 1. uninstall the AP from your car 2. download the upgraded program 3. run the upgraded program 4. sync AP to PC 5. installed the AP driver 6. PC detected the AP 7. click on help ->update to update your AP 8. install goes for about 30 minutes, then gets an error 9. I call Cobb and tell them about this 10. they tell me I have to mail it in to get it updated by them. 11. I ask if I can remarry it to the car and set it to stg 1 before I send it 12. they say it's not a prob 13. I go to my car and try to flash the ecu to stg 1 again 14. FLASH FAILED 15. I unplugged the test connectors 16. unplugged the OBDII port 17. tried to start the car, but it won't!!! HELP!!!!!!!! Link to comment Share on other sites More sharing options...
unstablementaly Posted February 13, 2007 Share Posted February 13, 2007 dude, did you re-marry the AP to your car? was the stock ecu map there? my vBGarage Link to comment Share on other sites More sharing options...
moviemadness Posted February 14, 2007 Author Share Posted February 14, 2007 I was trying to. when the AP was connected, the only two options were 1. install 2. sync with pc so I clicked on install it was identifying my car, and identified it correctly to 2005 Legacy GT 5MT then I chose the map 93 5MT or something like that. and when the status bar came out 0% 100% thing. I think this was like the storing stock map part or something, and then it just says flash failed so I think it got an error while remarrying the AP...??

unstablementaly Posted February 14, 2007 Share Posted February 14, 2007 yeah, kinda sounds like it. and quite possibly a fubared ecu to boot! put your test connectors back together and see if any codes come up my vBGarage Link to comment Share on other sites More sharing options...
bmorrisj Posted February 14, 2007 Share Posted February 14, 2007 ahh im going to say it again.... leave your key in the on position whenever there is anything other than a successful flash... your ecu flash is incomplete and restarting the ecu has put the current data in memory (or lack thereof) into effect. you have to pull it out of the car and send it out to get benchflashed....

moviemadness Posted February 14, 2007 Author Share Posted February 14, 2007 send it out to who? when it said flash failed, then what was I supposed to do? Link to comment Share on other sites More sharing options...
antny Posted February 14, 2007 Share Posted February 14, 2007 did you disconnect the green connectors? Link to comment Share on other sites More sharing options...

bmorrisj Posted February 14, 2007 Share Posted February 14, 2007 ahh, sounds like sage advice(from experience?) i yup.... you can probably send it out to cobb.... but your car is going to be out of service for a while Link to comment Share on other sites More sharing options...
hondas123 Posted February 14, 2007 Share Posted February 14, 2007 Call Cobb... A few members have been through this. U have to pull the ECU and send it to them. - The Mortgage Man Link to comment Share on other sites More sharing options...

bmorrisj Posted February 14, 2007 Share Posted February 14, 2007 do you have a laptop? use the ap cable and see if ecuexplorer (SSM) can communicate with it? if you take it to a dealer they will probably try to gouge you for ~$1000 (new ecu+reprogramming keys+labor) but if it was an AP error i would get in touch with cobb and let them know about this issue... so I definitely have to benchflash the ECU? is there no way around it? yep.... you have to raw write to the ecu and the only way that is done is to use the existing JTAG connectors on the inside of the case with special hardware....

moviemadness Posted February 14, 2007 Author Share Posted February 14, 2007 what's ecuexplorer (SSM)?? talking to cobb techs right now..on hold.. Link to comment Share on other sites More sharing options...
bmorrisj Posted February 14, 2007 Share Posted February 14, 2007 ecuexplorer is a free ecu logging tool that uses Subaru Select Monitoring (SSM protocol) if ecuexplorer cant see your ecu, then a subaru tech cant. thats more sage advice:lol: Link to comment Share on other sites More sharing options...
moviemadness Posted February 14, 2007 Author Share Posted February 14, 2007 ok just got off the phone with Chris from Cobb tech support. the option i have right now is to hardreboot the ECU I have to disconnect the negative battery wire, press the brakes to drain out the voltage, then let it sit for an hour, then try to start it again. If not I have to call them back tomorrow. I still have to send them my AP back anyway. See you guys in a few. Link to comment Share on other sites More sharing options...

bmorrisj Posted February 14, 2007 Share Posted February 14, 2007 install it on a laptop, plug in your AP cable (you may need a serial-usb adapter) plug it to the obd port (no green cables) turn on the key.... Link to comment Share on other sites More sharing options...
moviemadness Posted February 14, 2007 Author Share Posted February 14, 2007 i see.. would you mind being a lil more detailed please? it's negative 5 degrees out here, and I have to be 100% sure what i'm doing to be brave enough to go back out there..

bmorrisj Posted February 14, 2007 Share Posted February 14, 2007 oh ecuexplorer doesnt modify/write to the ecu, it just reads it... install onto laptop plug in ap cable start software --select the correct com port (lower left pane, right click select SSM communication) plug into ODB port turn on key +ECU should show your connected ecu click the + (plus sign) highlight realtime data view the whole right pane should be poplulated with selectable items you can read from the ecu (RPM, boost, AFR, lots of stuff) Link to comment Share on other sites More sharing options...
moviemadness Posted February 14, 2007 Author Share Posted February 14, 2007 ok, then if it doesn't modify or write the ecu, then what am I looking for? Link to comment Share on other sites More sharing options...
bmorrisj Posted February 14, 2007 Share Posted February 14, 2007 ok, then if it doesn't modify or write the ecu, then what am I looking for? to see if it sees/recognizes the ecu at all... sorry didnt meant to leave you hanging, left work....
