p.dubbin Posted November 16, 2003 Share Posted November 16, 2003 anyone know exactly what the "Check Engine" warning light on the right side of the warning lights actually means? Link to comment Share on other sites More sharing options...
GLCraig Posted November 16, 2003 Share Posted November 16, 2003 It's a light that comes on when the ECU has some trouble codes stored in its memory. Link to comment Share on other sites More sharing options...

torxxx Posted November 16, 2003 Share Posted November 16, 2003 do I have that type of diagnostics on my 86 GL carbed wagon? The ECU codes or what not? Link to comment Share on other sites More sharing options...
calebz Posted November 17, 2003 Share Posted November 17, 2003 Dunno.. do you have an ECU? some do some do not..I think. if you have an ECU, follow the listed procedure to check/decipher codes Link to comment Share on other sites More sharing options...
torxxx Posted November 17, 2003 Share Posted November 17, 2003 caleb, how do I tell if mine has a ecu? Link to comment Share on other sites More sharing options...
calebz Posted November 17, 2003 Share Posted November 17, 2003 Look under the dash on the drivers side, right above where your knees are when sitting in the drivers seat, right under the steering column.. if you have an ECU, it will be there.. If its there, follow the code retrieval methods in the link above Link to comment Share on other sites More sharing options...
imthenutt Posted September 17, 2014 Share Posted September 17, 2014 Can anyone help me clear my check engine light from a 1989 Subaru GL Wagon? I did the battery thing - I did the green connector dance - I warmed it up - got it into 4th gear. I am in a pickle because I live in California and I have to pass a smog emission test. It is automatic fail with the light on. Recently, I connected the green and white connectors - it cleared the code - I drove 3 miles and it was back on. The next day - I ran the smog - the connectors were still together - and i failed the test. When you run in that mode does it compromise some of the components? I thought I read that somewhere. I have the oldest cleanest Subaru in this area and the State is trying to force me to get it off the road! I only drive it about 1000 miles a year!

rdweninger Posted September 17, 2014 Share Posted September 17, 2014 Need pics of your Subaru before we can diagnose the problem. also, year and model would help. so we know how to read the codes, blinky lights or ODBII Link to comment Share on other sites More sharing options...
l75eya Posted September 17, 2014 Share Posted September 17, 2014 What does the code say the problem is? Link to comment Share on other sites More sharing options...
imthenutt Posted September 18, 2014 Share Posted September 18, 2014 I am sorry but I cannot seem to figure out how to put photos on this post - I feel like an idiot. The car is a 1989 Subara GlL Wagon - the connectors are under the hood - fire wall - drivers side. Two small white that fit together - two small green that fit together - an orange and a black. Thank you all for your time - I really appreciate all the help. I am donating my liver to a family member next month and I have parking enforcement ticketing me and DMV won't tag.

MilesFox Posted September 18, 2014 Share Posted September 18, 2014 caleb, how do I tell if mine has a ecu? What you have is a fuel pump control unit. And your ECS light is triggered by a microswitch in the odometer every 60,000 mi. Link to comment Share on other sites More sharing options...

l75eya Posted September 18, 2014 Share Posted September 18, 2014 You need to follow the steps outlined on this forum to pull the ecu trouble code before we can help. I'll try and dig up the process and post back. Link to comment Share on other sites More sharing options...

rdweninger Posted September 18, 2014 Share Posted September 18, 2014 Just to be sure, is it the check engine light or the EGR light. The EGR light comes on every 60,000 miles and can be cleared by swapping some plugs under the dash. As far as pics go... I was just wanting to see the nicest cleanest Subaru in CA. Was kidding about needing them to diagnose. Link to comment Share on other sites More sharing options...
l75eya Posted September 18, 2014 Share Posted September 18, 2014 The light will also say "egr" not "check engine" Link to comment Share on other sites More sharing options...

imthenutt Posted September 18, 2014 Share Posted September 18, 2014 Okay everyone - Here is the kicker... I hope everyone is ready to laugh if I have this correct: When I have been trying to "read the codes" - I have been wondering why I keep staring at the check engine light and it doesn't blink. Am I understanding this correctly that I need to find the actual ECU - the LED Light on the Oxygen Monitor and count those "blinky lights" as USMB Regular" calls them??? I also just read a little further and found: (Note: On 1989 Multi-Point Fuel Injected Models, the Oxygen Sensor Monitor Light and ECU are mounted under the rear seat package shelf, and are accessible only from the trunk.) Help a girl out please... what am I looking at to start blinking these codes? Thank you all - so much! Link to comment Share on other sites More sharing options...
wagonist Posted September 19, 2014 Share Posted September 19, 2014 Yes, there is an LED inside the ECU that you need to look for (it has a cutout for this purpose). The ECU on the XT is under the back parcel shelf The ECU on the Loyale type is bolted under the steering column. If you can sit just right, you can sometimes see the light in the gap between the plastic around the steering column and the next piece underneath fixed to the dashboard. Either that, or remove that lower part of trim to get clear vision. You only need a screwdriver to do this. Link to comment Share on other sites More sharing options...
