A: Hi there. The symptoms that you are having...

Hi there. The symptoms that you are having seems to be with a faulty PCM (powertrain control module, computer). If you are able to reset the computer by disconnecting the battery, then restart the vehicle, there is an issue with the software to the PCM. After replacing the parts to the engine and then the brake light and ABS comes on every time the engine light comes on with a code, then there could be an issue with the brake modulator. If the modulator is damaged or not working, the computer will see that the vehicle is unable to stop and will shut the engine down. Check the brake modulator out before replacing the PCM. If you need further assistance troubleshooting your vehicle, then seek out a technician, such as one from Your Mechanic, that can assist you with the brake light, ABS light, and engine light is on after replacing multiple parts.
