I have bought a '99 300M 3.5L, and the ABS and TRAC control lights have come on.


When i connect my Launch Creader VII+ i can read out error codes:


RF SENSOR CIRCUIT FAILURE
PUMP MOTOR NOT WORKING PROPERLY
SYSTEM UNDER VOLTAGE
PCI BUS COMMUNICATIONS
SYSTEM OVER VOLTAGE


I have replaced RF SENSOR and can read out Sensor values on all 4 Wheels - so i guess it is something else that is causing this.


Anyone able to send me in any direction? The car itself Works just fine.


Could it be the ABS block itself that needs to be replaced?


Or - any assistance would be greatly appriciated.
