95 SL600 wiring harness

I got hit by the wiring harness phobia in my 95 SL600.
Had a independant garage put on the new harness. At thousands less then Benz. Which upsets me, after all the money Benz got out of me in the last 3 1/2 yrs. Anyone with a SL600 knows what i'm talking about. Benz would not work out a good price with me. Anyway, harness went on ok. But now we are getting the ABS SRS lights on the dash, which also affects the throttle. Car is in "Limp Mode". They have a scanner for the car but are drawing some blanks. Could anyone give some Ideas. Throttle acuator is not opening all the way. And a slight misread on one of the computor boards. Some how they are all connected. Oh yeh at least the check engine light is no longer on. Sitting in Lancaster Pa.

RE: 95 SL600 wiring harness

Hello, I think that they have wires on the instrument panel wrong, The ABS,SRS wires should be on the check engine and vise versa. ABS&SRS do not effect the engine and will not put the car into limp home mode. The check engine light should be on as it is in the limp home mode. You have a fault and that will be recorded in the car's memory, but you need a code reader to find what is says, Malcolm

Why did you replace the harness in a first place,was anything wrong with the car?
As they say "Do not fix anything that is not broken"

RE: 95 SL600 wiring harness

Did you mechanic tell you what codes were read? Maybe you should read the codes yourself...All you need is a cheap LED from Radio Shack. I have written the procedure several times and it shouldn't be hard to find in the archives. And you can check this website to see the layout of the diagnostic connector and where to connect the LED and also interpret the codes: http://pages.prodigy.net/jforgione/MB_S500.html.

RE: 95 SL600 wiring harness

Sweet Vpwr, If the car is in the limp home mode(and it is)then the little lamp comes on and tells you.and if it was doing that before the harness change but now the ABS lamp is on when there is nothing wrong with the ABS they are obviusly the wrong way round(there was a small change on the instrument panel in 1996).Maybe your English is not very good as the gentleman said " at least the check engine lamp is not on now" In English that means that it was before the change. As for I do not your I do not know comments, I can at least repair at component level any modules in the car,and have been doing so for 50years, can you?[:)]Malcolm

RE: 95 SL600 wiring harness

unfortunately the ASR/ABS is connected to the engine management system and WILL trigger the 'limp mode' Try first 'reprograming' the steering angle sensor--engine running, vehicle stopped, turn steering wheel fron lock-to-lock and back to center. restart the car. If no-joy, then it is probable one or both of the electronic throttle actuator integral wiring harnesses is/are failing also. An excellent tutorial for this repair is fond here : http://v12uberalles.com/throttle_actuator_rewire.htm

Where did you get the new wiring harness and how much was it?

RE: 95 SL600 wiring harness

Dabenz Has not said yet if the check enginge light was on before the new harness was fitted. The ABS SRS system is not normally connected to the ECU as they have there own module, and even if the ABS goes down it does not affect the genral running of the car as you still have normal brakes Perhaps Bobterry99 can say if it is joined to the ECU.

The ASR is connected to the ECU but not the ABS though they share some of the same components. Malcolm

Have you had any luck getting MBNA to respond to this "silent recall"? See my previous posts with my experience with the same issues.
