I tested all 4 fuses in the Base Module, all checked okay.
The battery voltage is good. I disconnected the battery 2 days ago to clear the fault codes, I guesss this didn't work. I do not know how to clear the codes in Base Module or EA module...., very poor gas mileage. This problem started about month and half.

No CEL light and no ASR light, just very low power, can't go up hill and sometimes very rough in low idle.

Where can I download a wiring diagram or schematics for this car?

Thank you again for your help.
