Xc90 2004 fault code 0094 and CEM-1A64 communication with AOC control module ; Signal
Hi everyone I'm new to the forum and desperately need help with my xc90 , its driving me mad with anti skid message , I have the codes 0094 and CEM-1A64 communication with AOC control module ; Signal Missing .
I have changed my dem module and my pump is now working fine when I turn ignition on and all 4 wires have the exact readings for voltage as recommended going to the dem connector but still continue to get these permanent fault codes . I have changed my steering angle sensor aswell incase this was at fault but still anti skid service required.
Can anyone advise my next step

I had problems that kept occurring on my 2005 XC90, including Anti Skid messages. I went crazy trying to locate the problem and searched here for months.
I changed the Sensor under the RT FT seat as it is related to that problem. If it gets wet and it will due to the sun Roof Drain plugging, (check it). Also the Clock Spring in the Steering Wheel. But the messages all came up and would not go away.
Then I located a YouTube Video relating all these messages to the ABS Module and that too can cause all these anti skid messages.
Per information I learned the hard way, Volvo Began "Pressing" the contact pins into the circuit board in the ABS Module. Over time these pins come loose, thus you begin to get all kinds of messages. A "Knowledgeable and good" ABS Module repair shop can quickly repair these modules. You can actually do it yourself if you are inclined. I did send mine out and the so called repairs sucked so I sent it out again to someone else where it was repaired correctly and I have never had another error message since.
Our shop is repairing another 2004 Volvo XC90 right now. Same problem. I am going to attempt repair on the module myself this time. Hope it works.
The pins in the circuit board work loose. Repair is to use tiny needle nose pliers and bend over slightly , tightly each pin. then bond top back on. This is reportedly what repairs these. We have had several repaired now besides mine, so far so good.
