So I've had an intermittent issue with anti-skid service require popping up on my dash, but it stayed off for a few months so I hadn't been owrrying about it, thought I feared it might be the DEM. Then yesterday I had "anti-skid service required", "brake assist service required", and "engine system service required" all pop up at the same time. I brought it to the dealer that I know to have the scan it with their volvo scanner. They came up with the following codes.

BCM-0095 Communication between control units Communication problems with DEM
BCM-0103 Pedal position sensor faulty signal
CCM-001F Air quality sensor signal too high
CEM-6f71 Fuel hatch signal too low
DEM-0002 Pressure sensor faulty signal
DEM-0003 System supply voltage, DEM faulty voltage
ECM-130A Air leakage intake
ECM-6814 Turbo control - signal too high
ECM-9400 Brake pedal sensor - signal too high
ECM-990A Idle air trim - faulty signal
PDM-0021 Power window hall sensor 2 faulty signal
PDM-0042 Control module internal fault
SUM-0115 Shock absorber solenoid, front left side current too low
SUM-0201 Control module signal too low
SUM-0336 CAN-signal, ECM control unit faulty signal

Very overwhelming. The basic idea I get from all this is that I should replace my struts, brake pedal sensor, and my PCV system. What else do you guys think? All these codes together have me very confused I'm hoping you guys had some ideas. Thanks in advance!!!!!!

Battery. Your battery is doing this. Voltages are too low to run the modules and switches. If you let t run down it will set these codes. Recharge or replace battery and clear codes

If that was your first scan since you had the car that could be years worth of codes. Even if they were rare glitches, they will stay in their till you clear them.

Once you make sure your battery and charging system are well sorted, put a few miles on the car and get another scan to see what remains since they will be your current issues.
