I was going to get a used pedal 4M51-9F836-BK which seems the same as mine despite many differing vehicles using the same one. But I thought I should try your tip on checking voltage pedal to cem. And then it occurred to me lots of these silly problems can often be cured by a software update. Fords were notorious for it. What do you think? If so is there a way to establish what software version I have on the car and what software version is the latest? I guess the latest could be 5yrs old or more but its a good place to start, just ensure you have latest software update? If so how can it be done and what would the costs be ish? If you think its software first I'll go for that, then the pedal wire to cem, then maybe another pedal and after that if it still happens Im stuffed. Cheers |

you need to get a new plug shell for the throttle pedal and renew the terminals too , they have lost their springy grip on the pins , also the other end of the signal wire to the CEM put a new terminal repair wire on that too.

"as i said its never the pedal"
Well that saves a £40 punt then on a used one. "you need to get a new plug shell for the throttle pedal and renew the terminals too , they have lost their springy grip on the pins" You mean as in a new part? Whats that called in their lingo? "also the other end of the signal wire to the CEM put a new terminal repair wire on that too" OK thats the next project then thanks. Any thoughts on the software update idea? |

HOUSING 8690598 TERMINAL REPAIR 30765498 X 6 I usually run a new white wire between the throttle pedal terminal Pin 2 and and Pin 31 of Green connector G under the CEM on the left side as it goes up behind the dash and could be trapped up there somewhere .. software won't have any effect of a fundamental main control of the car ..

Is this the right part no HOUSING 8690598? I cant find it anywhere but a US volvo site, so at least i can see exactly what the part looks like. https://www.volvopartswebstore.com/p...6/8690598.html You mentioned elsewhere about some special tools for the pins. Lots of rubbish about so do you have any that are good in practice? I wonder if it might just be better to bypass the plug completely and make your own and extend the darn wires so you can at least work on the thing as its only 6wires. What exactly was the known issue beyond the female plugs going loose? And was there really no way of tightening them up a little with a fine probe push against the edges or suchlike, or even a thin coating of solder on the male pins? My son was a Ford service guy and said around the time of my car 2010 onwards they were always having software issues and constantly having to update them. He reckons it was one of the main sources of angst in the cars. Just realised I will need to get another pedal anyway because the wd40 buggered up the plastic shaft on the pedal so its very sticky now. Not terminal but a real PITA knowing its there especially in stop/start traffic. Cheers Last edited by Pete-V70 D5 2003; Jun 14th, 2021 at 07:20. |

You can use a pin to bend the retaining tag a little to get the terminal out . the new terminals have a better coating , gold plated in some cases ...

Good info!
Dad's car has never given any further grief, but it's useful to have the info stored, just in case... cheers James

OK back to pedal plug please. 1: Do the pedal wires just pull out of plug and are pushed back in? 2: What is the exact procedure advised to actually get at the plug let alone change wires? 3: You mention elsewhere "I usually run a new white wire between the throttle pedal terminal Pin 2 and and Pin 31 of Green connector G under the CEM on the left side as it goes up behind the dash and could be trapped up there somewhere" Do you mean change the pins in each plug too, so in effect a fly lead? The old gals gotta go now its jsut too little used and too much of a PITA. Many thanks. |
