Opel Astra H - horn doesn't work - how to repair the CIM module

[@Peedr]

This wonderful tutorial is beyond perfection. Thanks a lot for sharing with those of us whose cars suffer from the same fault.

[@piotrwalczak3368]

Wciąż pomocne - 2 tygodnie temu naprawiłem swój CIM (szwankował klaskon i zamykanie z pilota), teraz jak nówka :)

[@yukayuyu3844]

Thanks for the detailed tutorial, fixed my left stalk not turning on high beams. Moved the moving plastic part with contacts on the bottom of the PCB back into place and now it works perfectly fine, also scrubbed the through-hole pins so hopefully the horn thing doesn't manifest itself anytime soon. Airbag was indeed a pain in the back, for anyone struggling I would recommend pushing the screwdriver in at different angles (towards the center of the steering wheel) and pulling on the airbag until you feel it letting go a bit, then you know you can push as hard as possible to release it. The little while codewheel was difficult to remove as well but using a tiny flathead screwdriver works great for separating the brass pin from the case.

[@mist3ral]

My 57 Zafira had no horn/random radio volume issue. All I did was, disconnect negative battery terminal, push airbag out (didnt disconnect) and the small wires were all squashed. I carefully pushed them all to the sides whilst pushing the airbag back in. Reconnected battery...horn works every time and radio controls now work!! Really simple. The wires were squashed beneath the airbag...that's all.

[@yhshah21]

Bro just done the exact same thing and it started working, the little brown wires were squashed

[@NelsonRdm2Sanlez]

I'm having the same problem. Let's hope the same solution fix it.

[@yhshah21]

@@NelsonRdm2Sanlez also push the connector for right side in when airbag is out I found the connector was loose

[@amilzekria6635]

I have exactly the same issue however mine is now completely not working. When i watched this video all i saw was the big orange wires that connected the airbag i did not see any other wires. Are the orange ones the ones that you say got squashed???? Cheers fella

[@alprobert]

@@amilzekria6635 it's the really thin brown wires that come from the thumb wheel and into the main loom via the airbag section. It's a really tight mess!

[@alaaalshakkour]

You are a wonderful person!! The steps and explanation are very clear, I've done the same process in the video and now work wonderfully .. Thanks so much for this!!

[@slicerdw1]

Hi! So i've followed this guide and got success results! I had problems with the horn and left radio controls module so i followed this guide to open the CIM module. I applied a special product for cleaning and lubricating electrical contacts (don't use WD40..), didn't have to scrape, just cleaned ALL contact points. I also did an additional thing: I soldered the board external connectors (There are three of them). The connectors are not soldered to make the outer plastic box separate from the CIM board, and they are fixed to the PCB using special "legged" pins with no solder that might loose it's effectiveness over time. All works fine now! Thanks again insaneinvader!

[@ShaneyMacPaddyWhack]

Worked 100%, thank you so much! To those wondering whether to do it, it's a lot easier and quicker than it seems. There's less than 10 screws in total.

[@sebwright2900]

Was aligning the wheel and putting it back together ok im just worried about the wheel thing falling when I open the cim ?

[@INJETUK]

A+++ My partners horn didn’t work at all with or without lights on. Tried your recommendations and step by step procedure. Now fully working! Saved a few quid 👍

[@mattbennett7080]

Excellent guide. The clip 'fix' vauxhall fit FOC basically is a 10min job. The steering wheel need not be removed nor the airbag. The clip compressees the 2 piece steering control unit to allow the rusty / problem electrical contacts to better contact. Gets the car through the warranty period before it fails again. The contacts on my car were indeed oxidised. White film on aluminium. Other contacts are copper. Why vx used Al here? Cleaning didn't work for me but made the steering controls work again on left side only Methinks a new CIM needed or something else wrong. Already checked horn and earth. What is clear is that vxhall dealers have not bothered entering steering control box where code wheel is etc. Thumbs up for this video

[@jamiejeffries2548]

Hi have you got the link to this video? Cheers

[@StejiKait]

I will try tomorrow! Thank you so much the video is very clear! The world is better because of people like you!!

[@shroomskunk]

Thank you so much. Vauxhall wanted £80 just to run a diagnostic check and that's before parts. I've just done this and got my horn working again. You sir are a legend!! 👍👍👍👍

[@id15807936]

Having a car in UK seems expensive. The whole repair in my shitland would cost as much as just a diagnostic check for you mate. But i would be concerned about the fact they can steal the airbag while repairing the car.

[@rodgermogg897]

Worked perfectly, thank you! I didn't have the problem with the lights/volume switch, just that the horn stopped working. Fuses were okay and I had already replaced the wiring loom under the airbag. Also, no power was reaching horn, so concluded it had to be the cim. Fairly straightforward to do but had a little trouble re-attaching the black ring thing that sits under the centre of the cim casing. Took me forever to re-align it properly so that it would sit in place correctly, prior to putting the three attachment screws back in. Took a bit of working out but got there eventually. Bit like a jigsaw puzzle! My indicators were also starting to play up, not always catching on the first/second time. This is another known fault I believe with Astras. Not only annoying but can be dangerous. This was an easy fix by cleaning the contacts while the cim was in two pieces. Indicators now working perfectly. I am slightly puzzled that my cim did not have a small white code wheel fitted. However, everything seems okay without it!

[@lostinakl]

Hey Rodger, I followed this video and fixed the horn. However I now have issues with the indicator, it is not the same problem as yours but your experience could probably help. My indicators won't self-cancelling after I complete a turn, either left or right. Since there is no mechanical cancelling switch, I believe something goes wrong in CIM, maybe the angle sensor? Do you have any clue? or maybe just tell me which contacts I should clean, thanks.

[@juperrr]

Helpfull video. The hardest part, as you sayed, was removing the airbag. A philips nr. 2 screwdriver worked the best for me. Thank you!

[@majkabozja]

Hello everyone! I did everything like in video, but forgot to mark code wheel.... Assembled everything and my turn signal didnt come off. I disassembled it again and placed it like in this video, and it worked. Everything works, turn signals and of course steering wheel commands. I hope you all marked it like in the video! Thank you very much insaneinvader!!!!

[@ramazanozkan5359]

hello, good day, the same thing happened to me, after giving the signal, the arm does not drop, it stays like that, how should I follow it, can you help me?

[@garyaldridge4251]

Great Tutorial Video, I followed all the instructions and after I had put the unit back in it was working like a dream. I wasn't sure what chemical you had put on the contacts so I used a small amount of GT85. The notes and warnings like (THIS WILL DIFFICULT) were very helpful. Thank YOU

[@dumitrualexandru2286]

1. To remove airbag better use long hexagon driver as for bicycles. 2. Return steering wheel to center position before dismounting. 3. To remove levers I also use small hexagon driver of appropriate size.

BTW... i didn't have to remove stalks or the disc.

Guys, in case of mine, there was broken thread on metal plate, where block with triggers is located and fixed. So, it cause bad contact of SIM module and ignition lock. When i start the engine, horn wasnt work. After i fix this issue, horn do well! I fix it with putting into thread hole a peace of metal tape

[@DjAndySpb]

Don't ever try to remove plastic wheel the way it is done at 7:10! The pin is locked to the case and should pressed out from behind with a small torx for example, without force applied to the board.

Kind off did everything accordingly, but in the end the horn doesn't work even with lights off.. Did take it apart one more time, and cleaned again, will see what happens now. Do anyone have some ideas what could be the problem? UPDATE: After second cleaning and reinstalling - everything works! You are the best! Can't thank you enough!

[@philipmadhatter4006]

Martins Duboviks faulty horn it’s self

[@mattbennett7080]

Car fixed. Horn works and all steering controls. After cleaning contacts the horn and RHS steering controls still did not work. A forum post suggested unscrewing the buttons on stwering wheel for volume etc. As the RHS was still inoperative I tackled this. You need T20 to unscrew bolt from behind steering wheel. Thin flat screwdriver or wiggle / pull audio control out steering wheel. I had a garage already replace these a few yrs ago with new. I replaced new with old one after tugging cables. Plugged in old one. Result - horn works all time with lights on / off and with dash rheostat bright/ dim. RHS audio controls work flawlessly along with LHS. Battery drain of 150mA has gone. I checked this 10min before and left for 40mins - no change. After effecting this repair the voltage stays at .080A for 2mins then drops to 0.00A Maybe connector earthing/grounding to negative? Tiny wires looked in good nick. Worth a try. Saved £££ £115 OBD DIAGNOSIS £600 CIM £60 to reprogramme new CIM Hope this helps someone

@@mattsmith6158 I just got it fixed today, it was caused by bad code lock rotation it was a bit to side so it had to be placed as it was before. I tried contacting official Opel center and they thought that steering just needed some alignment and for that cim module code is required. Cim module code did not work, because code lock was moved a bit to the side. So i left official opel center and tried to find local opel electric, he said code lock was rotated a bit, so with computers help knew how to placed it into default position also he said he refreshed something in cim module software. So my advice, dont go to official opel center , look for local electric and explaim what was done.

Sorry i did not answer your question, from horn point of view, it never worked so all i did is cleaned the contacts. Please do not rotate code circle by accident or you will have same issues as i mentioned above.
