Ok, now we can reconnect the connectors one by one. 1. The electronic unit is already connected and it measures infinite, so this is good. 2. The black connector of the check panel is connected, but we need a clear measurement. This one should be remeasured (three digit value). 3. Reconnect connector one from the instrument cluster (the buttons) and measure (three digit value). 4. Reconnect connector two from the instrument cluster (the lights) and measure (three digit value). 5. Reconnect connector three from the instrument cluster (the clock) and measure (three digit value).
I have an issue now! And I am getting worried: all connectors are back connected The stop light light in the check panel is on when I press the brake!!! Went back to the boot and disconnect but the bulb to check it but it is fine but I have noticed the following…..There are 2 bulbs with double filament each…..when I press the brake on the drivers side both are on but on the passenger side only one is on… I have a question…when I turn the lights on, on first position…..only one bulb is on... on each side, not both…..I mean…shouldn't both on each side be on… ? also….when I turn the P switch on…happens the same…only the lower bulbs are on….may be here is the issue? Also….the small bulbs that are suppose to illuminate the boot are not working….they were not working before I think
I would advise to first solve the first issue (blowing fuse 17), the measurements are important to take conclusions. The weird behavior can be explained because we disconnected a wire from connector J. I will look in the schematics about the single and double lamps.
. I think you better post some pictures as you go... a picture is worth a thousand words. It will minimize any possible misunderstandings.
This is how we are now after the failure in the brakes: 1- All disconnected again: this means 3 connectors form the dash, the electronic unit and the black connector from the check control. Like this measures: 1 2- Wen I connect the electronic unit, measures: 0,003
I don't think there was a misunderstanding, only a misinterpretation of the measurements. But at least two valuable conclusions are valid: 1. Fuse 17 does not blow if the wire of connector J is disconnected so the fusebox is probably ok. 2. If all buttons, lamps and units are disconnected there is no short measurable so the wiring harness is probably ok. I am sure we will find the cause! But it takes some time.
That's 3 ohm, this is a relatively low value. I would advise to disconnect the blue connector of this unit and only connect the green one and measure again. Image Unavailable, Please Login
Done: If I connect any of them back, value is still 1 If I connect both at the same time, value comes down to 0,003 So when both are connected to the unit, value comes down
In that case only connect the green one. Then connect the black connector of the check panel and measure again.
If I connect the connector that has a green (verdi) wire (for me comes from the lower part of the electronic unit, not from the upper part as shown in your diagram. The connector that comes from the upper part for me is composed mainly by reds and yellows wires), stays in 1 but when I connect the black switch in the control panel .the numbers just go crazy from 0.006 to 1.4 ..
It is the connector with on two places a double and-or triple wire. You should not switch the ignition on when measuring. I think the measurement will be stable when you switch off the ignition.
After measuring this one you can measure the rest (all with ignition and all lights off): 1. Reconnect connector one from the instrument cluster (the buttons) and measure (three digit value). 2. Reconnect connector two from the instrument cluster (the lights) and measure (three digit value). 3. Reconnect connector three from the instrument cluster (the clock) and measure (three digit value).
Ok, maybe there is our problem! Disconnect the black connector and proceed with the three instrument cluster connectors.
I advise to leave this black connector disconnected, we will find out later what the problem is. Now it is time for the three instrument cluster connectors. I am very curious about the results
Black connector disconnected and measure report: 1 If you do not mind, I will continue tomorrow…very tired and my mind is not "connecting" at the moment. Let's hope that we will resolve it this week. Again, many many thanks!
No problem, it's my pleasure. We are making realy progress now so i am very confident we will find the issue soon!
Mayday, mayday!! I'm in a light plane over Rotterdam, the pilot's got stuck in the toilet with a stewardess and the co pilot is drunk. I'm the only guy here that can land this baby BUT I need someone to talk me down to the ground in this thing. Is there a 'Johan' in the house?! Seriously Chaps, great job we are in the edge of our seat here i the UK! https://www.youtube.com/watch?v=SmHeP9Sve48
Good nite…too tired to continue today. I will tomorrow, you have my word…sorry…to many hours working in the office today
