CUSTOMER CONCERN The scan tool cannot communicate with the IMA system, and DTCs U0110 and U1205 are stored. CAUSE Testing confirmed a failed Intelligent Power Unit fan module. The failed fan module caused the No. 61 10-amp IMA fuse in the auxiliary underhood fuse box to open. CORRECTION Remove and replace the Intelligent Power Unit fan module and the open No. 61 10-amp IMA fuse, then verify IMA-module communication.
