Have you checked the connectors in the wiring harnesses for the ABS unit and associated components for water intrusion or corrosion? The codes that you've posted (details below) all point to a poor electrical connection in the circuit(s) or an open or short in the circuit(s). That could be either due to corrosion, liquid intrusion, a wiring harness rubbing against something hot or something that vibrates and has damaged the wiring. If the wiring and connections are all intact and there are no opens, shorts to power or shorts to ground, the next think to look at would be the modules and/or sensors to make sure they're operating within spec.

I hope it does. are you asking where it is? Should be within reach of the driver..

If the fan works on med but not high or low it is an indicator that the resistor has gone bad. Since the motor works sometimes, it's a pretty safe bet that the motor is good. A 12v test light will tell you if it's the switch or the resistor.

Could be fuel related. First thing to check for that would be a fuel pressure test. Even though the pump is working, the proper and specified pressure must be kept in the fuel rail for the injectors to work right.And/or have the computer scanned for any diagnostic trouble codes. Many national parts stores do free diagnostic scans.
