andy.michael Posted December 4, 2014 Share Posted December 4, 2014 hi guys i have recently bought a 97 forester but i cant get any of my diagnostic software to work on it , i have tried elm327, freessm, proscan,to name but a few but none will comunicate with my ecu. i have read that freessm only works with 99on models so was wondering would a straight swap with a 99 ecu work on my car as is or is there any software out there that works with this model. thanks in advance any help will be apreciated.

stants Posted December 4, 2014 Share Posted December 4, 2014 Hello welcome, you are correct in thinking that nothing works apart from the green and black diagnostic connectors under the dash for providing basic info, being a 97 car is yours a jdm import? If so an ecu swap won't work as the jdm cars have different turbo injectors and cams so it won't run very well. Also i've been told the UK cars have an immobiliser in the ecu so you'd need a matched set of keys otherwise it would start up then cut out. A proper garage version of ssm will work but it costs about 6 grand Quote Link to comment Share on other sites More sharing options...

Mr B Posted December 4, 2014 Share Posted December 4, 2014 A lot of the professional readers will work on the pre OBD2 setup of Subaru. Likes of the early snapon readers, Launch readers, they can be found used quite cheap these days. Another optioin could be TOAD software & cable, this would be less than £80 for software to run on notebook & a quality cable. Have heard the TOAD system supports pre OBD2 compliant subaru but never used it myself but anyone interested could get that confirmed via TOAD as it is probably cheapest decent kit if does. Obviously you can still connect the diagnostic plugs & read codes via flashing CEL ... http://uk.subaruownersclub.com/forums/topic/2366-manually-reading-ecu-codes/ Another option for those who want a bit of a project is looking at the Evoscan software & digging up some info on tweaking a cable to link it to the Subaru ssm1 or ssm2 connector layout ssm1 is a 9 pin plug and normally on likeys of 1990-1996 subarus ssm2 uses the standard looking 16pin OBD2 socket but is not OBD2 & only a few select pins are used. Is possible to make a cable usb or parallel port for either at less than £10 You can also buy them but price for decent ones is probably £30+ Only downside is evoscan does not suport all ECU ROM version of subaru as there were so many but it does the majority & worth a play for the curious home mechanic. Couple of links below to get people started. http://www.4bc.org/vanagon/engine.html http://www.microtopia.org/personal/subaru-ej22e-odb1-ssm-to-reader-options https://drive.google.com/file/d/0B7Ub2apq5-pfdnB6MlRoRC12Wnc/view?usp=sharing http://www.evoscan.com/evoscan-gps-obdii-cables/details/8/1/performance-vehicle-pc-diagnostic-interfaces/evoscan-subaru-select-monitor-i http://www.vwrx.com/index.php?pg=selectmonitor Edit : more useful info> make a ssm specific cable https://drive.google.com/file/d/0B7Ub2apq5-pfMm03TXFhSml6Z2c/view?usp=sharing http://www.alcyone.org.uk/ssm/sma.html USB to FTDI FT232RL cable for ssm1 (less than £5) http://www.ebay.co.uk/itm/6pin-FTDI-FT232RL-USB-to-TTL-Serial-cable-Converter-Adapter-for-Arduino-UNO-R3-u-/291399003192?pt=LH_DefaultDomain_3&hash=item43d8bbec38 ssm1 female connector harness/plug (less than £5) http://www.ebay.co.uk/itm/SUBARU-JUSTY-LEGACY-XT-TURBO-WIRING-HARNESS-PC2-29-4-/250664110928?pt=LH_DefaultDomain_3&hash=item3a5cbecb50 freeSSM software https://drive.google.com/file/d/0B7Ub2apq5-pfNHVKZE13clFxc1E/view?usp=sharing EvoScan https://drive.google.com/file/d/0B7Ub2apq5-pfdnB6MlRoRC12Wnc/view?usp=sharing Select Monitor https://drive.google.com/file/d/0B7Ub2apq5-pfQ01ONloyclJyVjg/view?usp=sharing JECscan https://drive.google.com/file/d/0B7Ub2apq5-pfcnpxNGtHWEl0Q0k/view?usp=sharing *worth noting a Vag-Com KKL 409.1 spec usb obd cable will generally work for late subarus with obd2 style connector but not full obd2 compliant & allow good communication via the freeSSM software. ** secret with the VAG cable is supports ISO9141 protocol & that matches protocol on pre OBD2 with the 16 pin OBD2 looking plugs. I will do a test with a cheap (less than £5 at time I got one) VAG cable & if works will do a post on it including links then you guys who just missed OBD2 will have some half decent diagnostics at price of a takeaway. will be after christmas before get the copy cable but for sure will update on it as soon as can. Link below is one I tested off eBay as a cheap solution for late model ssm2 use & OBD2 use. worked fine and received quick.http://www.ebay.co.uk/itm/351567535286 eBay uk optionhttp://www.ebay.co.uk/itm/322239774503 With pre 1999 model subarus (UK, EU, JDM) on ssm1 best you can do is make the ssm1 cable & use it with evoscan which will allow data monitoring/logging or Select Monitor 1999 to 2002 will work with ssm2 (looks like obd2 plug but not but works with ISO9141 supporting OBD2 cable) freeSSM works great on this ( https://drive.google.com/file/d/0B7Ub2apq5-pfNHVKZE13clFxc1E/view ) 2002 onwards works with freeSSM via OBD2/ssm2 (freeSSM support usb cable only)) or any OBD2 software (via OBD2 cable or bluetooth-OBD2 elm327 dongle) such as Torque app for android or OBD autoDoc for notebook pc which support usb-obd2 cable or BT & WiFi dongles.

andy.michael Posted December 4, 2014 Author Share Posted December 4, 2014 thanks mr b very useful, will look into this and keep you posted. on another note scanned the car this morning by connecting the black pins and all was good then drove the car this evening and it seemed to intermitently be firing on three plugs, will check in the morning.(hope its just a plug).

Rick 2014 Posted December 4, 2014 Share Posted December 4, 2014 Try your leads then there prone for mucking up. Quote Link to comment Share on other sites More sharing options...
Mr B Posted December 4, 2014 Share Posted December 4, 2014 Indeed, leads are very likely at fault. Couple of lead options below if needed. Prospark being cheap option but they not bad, used them on 2 of my own Foresters & run of the mill Subarus for customers & they have proved durable & almost faultless. http://www.ebay.co.uk/itm/PROSPARK-OES1234-Ignition-HT-Lead-Set-SUBARU-IMPREZA-2-0-WRX-STI-2-0-WRX-TURBO-/350928318911?pt=UK_CarsParts_Vehicles_CarParts_SM&fits=Model%3AForester|Plat_Gen%3ASF&hash=item51b4f531bf Better quality option from UK manufacturer, about £50 inc P&P http://www.performanceleads.co.uk/ShowDetails.asp?id=901&code=FLA276 1 Quote Link to comment Share on other sites More sharing options...
Rick 2014 Posted December 4, 2014 Share Posted December 4, 2014 Mine just happened all of a sudden.The heat kills the leads.I changed them and the engine was fine after that Quote Link to comment Share on other sites More sharing options...
Mr B Posted December 4, 2014 Share Posted December 4, 2014 combination of heat & vibration, Normally fail near clip for plug but saying that the OEM ones do last for over 10 years as a rule. have had original on old legacy of mine that done 14 years & 160+K mls on original leads. Most of the problem is sloppy independents with component plan servicing who throw your nice OEM ones away for worst crap at the motorfactors then regular faults start building up ... Get at least 2 subarus a month with intermittent misfire sometimes with flashing CEL or a spot of very intermittent hesitation & most times it a bad lead. Done one last month & it had been to Main Dealer for same fault, they had replaced O2 sensor & with diagnostics & labour the bill was £300, problem seemed solved but within 3 days the same fault happened again, owner struggled with dealer mainly as fault didn't happen when went back for them to test drive. Ended up at my garage as owner lost faith in dealer along with too much cash & wasted time, we sorted it for £45 all in . Don't always work out as easy at that but nice when does ... 1 Quote Link to comment Share on other sites More sharing options...
