whosaidwagonsarejustforfamily Posted July 8, 2015 Report Share Posted July 8, 2015 Hi i was wondering if someone could please help. I will start with the history, 1 1/2 years ago my Anti-skid message would come on and off sporadically.I checked for codes: bcm-u041464 (invalid data received from 4wheel drive clutch control module) along with other codes dem-p188914 (oil pressure pump performance).I first replaced the Aoc pump with fluid and filter. Message came on and off again.I than removed the Dem and had it repaired. They sent it back no problem found.I booked it in to Volvo dealership. Was recommended to try the haledex temp sensorreplaced the sensor same issue! (ANTI-SKID MESSAGE). The dealer said it may also pump again overworking. Anyone with thoughts? Thanks ****************UPDATE************************ So I sent my BCM in to a module repair centre and they said it was faulty and cannot be repaired. I ordered a new module and installed it and had it programed to my car. But I am still getting codes bcm-u041464 and dem-p188914. Anyone have any more suggestions? I do have access to a VIDA, is there any other things to check? Thank you for your time. Link to comment Share on other sites More sharing options...
Fran9690 Posted July 8, 2015 Report Share Posted July 8, 2015 I've seen where this dtc returns after replacement of pump and temp sensor. Clutches wore out due to excess slippage from weak AOC pump, so the whole AOC needed to be replaced. Link to comment Share on other sites More sharing options...
whosaidwagonsarejustforfamily Posted July 9, 2015 Author Report Share Posted July 9, 2015 Oh, are you saying the clutch packs are no good in the AOC? Can I rebuild it? Link to comment Share on other sites More sharing options...
Fran9690 Posted July 10, 2015 Report Share Posted July 10, 2015 Yeah, the clutches go bad in the AOC. As far as I know, you can't rebuild, at least not from Volvo that I am aware of. We put in a lot of used ones from Eerie when the customer doesn't wanna fork over the $5k or whatever ridiculous price it is for a new one.

whosaidwagonsarejustforfamily Posted July 16, 2015 Author Report Share Posted July 16, 2015 I should mention that the AWD sometimes works. When driving the vehicle everything seem fine, AWD works, no display error message. After about 5 or so minutes the light will come on and the AWD stops working. With the V8 it is pretty easy to get the front tires spinning without the AWD so it is easy to see when the AWD is working or not. Is it common for the AOD clutch packs to give you about 5 minutes of use before it quits? Thank you for your time. Link to comment Share on other sites More sharing options...
Fran9690 Posted July 18, 2015 Report Share Posted July 18, 2015 It overworks the pump when it sees the slippage, so it probably shuts it down to prevent further damage. I've had a similar issue on a V8 XC90. Would engage harshly the rear wheels when driven on lift. When codes cleared and driven in figure 8 around parking lot, DEM pump dtc would return after a new pump was installed. Problem was in the AOC itself.
