ABS Current Codes
C0265 Solenoid Valve Relay Circuit
ABS History Codes
C0241 PCM Indicated Requested Torque Malfunction
C0242 PCM Indicated TCS Malfunction
C0245 Wheel Speed Sensor Frequency Error
C0246 Right Rear Solenoid Circuit Malfunction
C0251 Left Front Wheel Speed Sen. Ckt. Open or Short
C0252 Active Brake Control Sensors Uncorrelated
C0265 Solenoid Valve Relay Circuit
C0298 Traction Control Malfunction
Codes read by a Innova 3160.
I verified the EBCM ground is not the issue by unbolting it from the frame,
bolted it to a 8ga jumper wire and gator clipped the other end to the
negative battery terminal.
The C0265 code will generally trip within 3 minutes after turning the key
to the on position (engine off, and no peddles depressed).
If no codes trip 4 minutes after turning the key on, I can tap once on the bottom
of the ABS Solenoid and the C0265 code will instantly trip.
I would much appreciate some guidance.

With all the error codes, I'd suspect a control module malfunction. This video and guides will help you change it out.

You will need to have the new module programmed to your VIN number or it will not function.

A shop with the correct scan tool can perform this for you.
