You can read the system voltage on the dash while its acting up by holding the upper and lower buttons on the left side of the dash display.
If you read the codes in the CCU it may tell you if it is high volts or low volts.
If its high volts check the voltage drop from the alternator output stud to the terminal block stud under the air filter.
