2000 Volvo C70 Two Wheel Drive Automatic 147000 miles

I have A 2000 c70 volvo. The check engine light is on, transmission arrow flashes, the abs warning light is on, and intermittently the instument panel goes blank. I 've recently had the ABS control module replaced, speed sensor, brake switch and a few other repairs done. Has anyone had these problems and can shed some light on what the problem may be?

WHEN HAVING AN ABS LIGHT WITH A CHECK ENGINE LIGHT AT THE SAME TIME, AFTER REPLACING THE ABS MODULE, EVERYTHING SHOULD HAVE GONE BACK TO NORMAL. SOUNDS LIKE THERE MIGHT BE A HIDDEN SHORT SOMEWHERE IN THE CONNECTIONS. WHAT ARE THE CODES THAT ARE COMING BACK?

Some of the codes that were found and read not active are tcm-001f speed sensor, tcm-e003 faulty configuration, cdm-0001 speed senor signal missing, cdm-000d communiction, and ecm internal fault. There also were some codes found that the status was unknown such as abs-0011 front left wheel faulty signal, abs-0092 control module, abs-0093 control module, and abs-0095 control module. My mechanic wants to install a new ignition switch in the car, could that be part of the problem?

WAS THE ABS MODULE REPLACED AFTERMARKET OR FACTORY?

IF CODES FOR ABS WHEEL SENSORS FAULTS, SPEED SIGNAL MISSING FAULTS ARE COMING BACK, IT SOUNDS LIKE THE FAILURE IS IN THE USED MODULE. IF THE MODULE REPLACED WAS A NEW PART FROM A VOLVO DEALER, THEN AT THAT POINT IT WOULD BE A DIFFERENT SCENARIO.
