This video is about how to use a OBD1 diagnostic code reader on W124 W126 W140 W201 Benz Find more information about the code reader here: www.mercedesco...
Hello Ralph; Always glad to get some extra help diagnosing electrical woes. Now I'm gonna have to go look and see if mine has the same 8-pin connector yours has. Don't think I recall seeing it before, but as you pointed out it normally covered. Have a great day my friend. Best wishes & warmest regards.
If it is installed then you will find it behind the engine firewall just to the right of the battery's positive pole. I have found a photo of a blog post that shows where it should be. 68885d1245191736-how-diagnose-engine-codes-89-300e-p4105067x.jpg
@@fritzjrundhaug81 I currently do not offer parts etc, but here is one of many choices of such a code reader on Ebay. I would give that a try. www.ebay.com/i/222481161915?chn=ps&norover=1&mkevt=1&mkrid=711-117182-37290-0&mkcid=2&itemid=222481161915&targetid=1098133263004&device=c&mktype=pla&googleloc=9006117&poi=&campaignid=11616981724&mkgroupid=114637734633&rlsatarget=pla-1098133263004&abcId=9300455&merchantid=6296724&gclid=CjwKCAiAudD_BRBXEiwAudakX99Vj-XnLP2S1jW2Oq9-vgw0sijTefOuBhDW-s3LDtJO8yru3SVCJBoCoQEQAvD_BwE
Hi Michal. Unfortunately, you are experiencing the top number issue with OBD1 diagnostic tools. The issue is that defective cables and /. or circuits can cause for there to be a continuous fault signal that causes for the LED to be lit the moment you apply power. The only way that I know is taking a power probe and trying to find those faulty circuits/ wires - it is a tedious process making the use of a OBD1 tester often pretty much useless.
@@michalmuszynski6942 Not necessarily. That can introduce more unknown variables. Testing key circuits one by one using a power probe is likely the best way to isolate problems.
@@straybenzes It was not available for the '88 & '89 on FED models. It was available for those model years only for CAL compliment models. Believe me, the test socket of my '88 300SE lacks any metal receptacle to plug into where your directions tell you to plug into to make the test.
My OBD1 impulse code reader doesn’t work on my car yet I recently got a check engine light so it had to be working? I mean I followed the wiring and it appears to inside the dash on the passenger side so I’m assuming it glides over to the driver side
@@straybenzes I’m not gliding over anything I’m just saying I chased the wiring from the onboard scanner to the passenger side of the vehicles. I unplugged the battery, cleared the check engine light and eventually it came back again. I bought a computer to plug into the OBD1 but will it work? Because the light doesn’t come on so I’m assuming it’s dead
@@plissken94th57 It is probably dead. That is quite the find if you found an ODB1 reader that plugs into any computer. The functionality remains the same though - it still only reads the number of impulses. I have it easier to just bite the bullet and checking one associated system after the other.
