Software?
Here's a recap of my version of the Power Seat Issue in a 2001 S60
I have the same condition on my driver side power seat on a 2001 S60. All the adjustments work perfectly including MEM settings - but only for the first 45 seconds after I unlock the doors. Then nothing. No intermittent, No sputtering. Nada. The only way to get controls working again is to turn off the car, exit, lock the doors, wait a while, then unlock the doors again. Then I get seat control again for about 45 seconds. If I leave the door open while adjusting I get more time. When the seat does work, it's perfect: all controls, full power, full memory functions, no switch problems.
My mechanic rebooted my car computer as a stage 1 trouble shoot. Problem came back.
Then I swapped in a used Seat Control Module that I bought as a second stage troubleshoot. It behaved exactly like the original power seat module.
So, I swapped them back and that's where I'm at now. The problem must be upstream of the module and it seems software based. According to the manual, the power seat has three basic programs:
1.) Door open, key in off position: 10 minutes of adjustment
2.) Door Closed, key in off position, 30 seconds of adjustment
3.) Door Closed, Key in ON position, always allow adjustment
It's as if the line of software code that tells the computer to continue allowing seat adjustment power for #3 (when the key is in the on position) is corrupted.
Anyone know what I'd ask for at the dealer that is the equivalent of an operating system restore and update? Sort of like reloading Windows from the disc after a major crash? I'm thinking that may unscramble whatever line of code is scrambled.
Here's what finally solved it:
Mine was fixed in a software reload. I asked my mechanic to download the software from Volvo and reload it onto the PSM.
I happened to have been getting a new ETM, which required software service - so, I asked him to get the PSM software at the same time. Saves some money as I think indy mechanics are charged a big fee to log on and then a smaller fee per download.
Worked for me. No new hardware. My problem was all software side. PSM Reload took care of it.
I don't know what it cost as it was rolled into the ETM charges, but it probably would cost around $260 if you had to have it done as a service by itself.
NOTE: My mechanic reloaded all the systems on my car on this service. So, I can't say for certain that the PSM reload alone took care of my power seat issue. I suppose it could have been a combination of reloads. But likely...
I hope this helps others. I didn't have a working Power Seat for years until now. It's been stable for months now. Definitely solved.
