Question about Mercedes-Benz CLK

1 Answer

Just bought parking sensors for 2006 CLK 200. Fitted beautifully, but due to reversing light having bulb-failure sensor, I need to fit a relay. No problem, except WHICH of the 5 wires in the "block" going into the rear light cluster is for the reversing light? Any help MUCH appreciated

    Hello there. Thank you for your research - in the old days they gave you a wiring diagram inside the handbook! I was hoping not to have to have the hassle of taking out the back lens to see where the reversing light fits in to the "block", so I'll use your suggestion to try and find a grey/yellow or a grey/blue.

    Whilst I have you, it seems the relay has to have one lead attached (in the trunk) to a permanent + feed from the battery. Well I'm not a complete idiot (!) but I can think of anything in the trunk area that has a permamnent + lead to it, for me to take a line off. Obviously the bodywork is - , so anything connected to this + will be running 24/7/365. Any suggestion?

    I live in Switzerland by the way, near Geneva. We were in Quebec at the end of last year, in September, and look forward to going back!

    Robbin

    Hi Bernie,
    Once again, thanks for the response and help, although running a wire from the battery to the rear of the trunk was not really what I was hoping for! Not your fault, however. I am going to try without the relay first, i.e. wire the control box for the parking sensors directly into the negative (bodywork) and the wire for the reversing light. Im pretty certain they are right when it says that will PROBABLY (thats whats giving me hope here!) cause a false signal on the dash computer to say there is a bulb out and/or a beep from the warning alarm from the sensors every 30 seconds. However, its a quick fix. Next up, if I have to use the relay, I was thinking about just buying a second 12 volt nicad battery and keeping it in the well on one side at the back of the car (masses of room) and remembering to charge it up once in a while. Surely this little ****** can't draw much power, and its only on when the reversing light is on?
    So, you must live up by Sudbury or somewhere? Years ago I used to work in NYK, and Scotia Bank Toronto was one of my largest clients, so I was visiting TO almost once a month for 2 years ! One of my friends at the bank (my client) took me "up North" a couple of times for the weekend, and we went up to the Algonquin Provincial Park, coming back down via Sudbury. Nice part of Canada.... more to see than Medicine Hat !

Hello robbind.
Not sure where you live in the world.
I am in Canada and your specific model is not listed in my manual.
I looked up the diagram under a CLK 350, I hope it is similar.

The system uses multiplex wiring, a signal is sent from one module to another eliminating the need for a bunch of wires to operate everything in the rear.

To find the wire color you need you may need to go directly to the bulb in the tailight assembly and find the proper wire.

On the CLK350 model the wires are Gray/Yellow to the right side and gray/blue to the left.
There is a module in the trunk that these wires lead to. It is a positive signal.

I hope this helps you with your installation. Thank you for using FixYa.

    Hello Robbin.
    I just went through the complete rear lighting diagram on the CLK350 and there wasn't any full time 12 volt positive source.
    All the lighting goes through the modules and they do not show internal module diagram to trace it through.
    You may end up having to run a fused wire back from the front in order to operate the device.

    I live about 80 km from the Quebec border in Ontario and 350 km north of Toronto.
    Snow on the ground and ice on the lakes. Winter has arrived.
    One of my customers moved here from Switzerland about 20 years ago. A very fine fellow, hard working and good sense of humor. Are you all like that over there? ;)

Hi guys, I have a ford transit connect LWB 2006, I've bought reverse parking sensors, but I can't seem to find out what colour the wires are for + & - for the reverse parking light?


Does this hook up to the transmission range sensor switch on the tranny? If so use a 12 volt test light ($5 at any auto parts store or online) and put the truck in reverse and probe the wires at the range switch, when you get a light in the test light that should be it, to verify shift out of park and the test light should go off.

Where is the backup light sensor for 2003 cadilac deville


Hello: If you mean what turns the back-up lights on, the lights are controlled by the park neutral switch which is mounted on top of the transmission on the drivers side of the car. If you haven't checked the bulbs you need to do that first. Remove the rear license plate, then remove the screws that hold the molding behind the license plate then you can access the bulbs for the back up lights. If bulbs are good check the Park/Reverse fuse in the rear fuse block, if fuse is good check the reverse relay in the rear fuse block. The rear fuse block is on Left side under the rear bottom seat cushion.

My 1995 neon has ~105K miles, just passed emmissions with flying colors 1 week ago, and the ''check engine light'' came on. I have checked oil, coolant, brake juice, fan belt and air conditioner belt. Car...


the light has nothing to do with oil or coolant levels. it comes on for one of the following reasons. You will need to have the system computer memory tested to see which fault the system has.
CODE Description of Trouble Code
11 Timing belt skipped 1 tooth or more from initial learned value, Intermittent loss of either camshaft or crankshaft position sensor, No crank reference signal detected during engine cranking
12 Direct battery input to PCM was disconnected within the last 50 key-on cycles (normal)
13 No change in MAP from start to run
14 MAP sensor voltage too low
15 No vehicle speed sensor signal
17 Closed loop temp not reached or engine cold too long
21 02s sensor problem (oxygen sensor), upstream or down stream
22 Engine coolant temp sensor out of range
23 Intake air temp sensor out of range
24 Throttle Position sensor out of range
25 Idle air control motor circuits, target idle not reached (+/- 200),vacuum leak found
27 Injector control circuit
31 Evap purge flow monitor failure or evap solenoid circuit
32 EGR system failure
33 A/C clutch relay circuit
34 Speed control Solenoid circuits
35 Rad Fan control relay circuit
37 Torque converter clutch solenoid CKT or park/neutral switch failure
41 Generator field not switching properly
42 Fuel pump relay control ckt, Auto shutdown relay control ckt, No ASD relay output voltage at PCM, Fuel level sending unit volts out of range, Fuel level unit No change over miles
43 Multiple/ single cylinder misfire
44 Battery temp sensor volts out of range
46 Charging system voltage too low
51 Fuel system lean
52 Fuel system rich
53 Internal control failure
54 No Cam signal at PCM
55 End of error messages (If you get this only, no errors were found)
62 PCM failure SRI mile not stored
63 PCM Failure EEPROM write denied
64 Catalytic Converter Efficiency Failure
65 Power steering switch failure
