Where to start ???
Post the codes CORRECTLY ....
They have a leading character (P=Powertrain, C=Chassis, etc.) which is needed because, for example, there is a P0563 and a C0563 and they mean completely different things.
Also after the code there will be either a "C" or an "H" (sometimes both) indicating whether the code is Current or History. With some codes it helps to know the status, though EBCM codes always go to H status when you shut off the engine, so it is less important for those.
Once you post the codes someone will be able to help you.

C1217 Pump Motor Relay Contact Circ Open
C1221 LF Wheel Speed Sensor Input Signal is 0
C1222 RF Wheel Speed Sensor Input Signal is 0
C1225 LF Excessive Wheel Speed Variation
C1226 RF Excessive Wheel Speed Variation
C1233 RF Wheel Speed Circ Open or Shorted
C1234 LR Wheel Speed Circ Open or Shorted
C1243 BPMV Pump Motor Stalled
C1255 EBTCM Internal Malf
C1278 TCS Tmporarily Inhibited By PCM
I'm suspecting these aren't all the codes in your car ... the PCM usually sets a code when C1278 posts ....
The three "bad" codes are the C1217, C1243, and C1255. If these are correct you will need to replace BOTH the EBCM and the BPMV ..... the parts alone, at list price, are about $2,500.00 ......
First thing I'd do is check the wiring connectors to the EBCM. Look for corrosion, water inside, anything that would cause bad connections. Second thing is check and clean the grounds for the EBCM ... they are G103 and G108.
G103 is located on the left frame near the EBCM. G108 is located near G104, under the battery tray. G104 is the main battery ground ... G108 is just behind it.
I'm hoping that G108 is corroded and cleaning it will get you going again.
