Check the Denso part number on the cooling fan assembly. The P/N should be AA222750-0753, AA222750-0763 or AA222750-0773. If not, replace the cooling fan assembly using one of the part numbers shown here. Also, replace the IPDM E/R (intelligent power distribution module, engine room). Use ASIST on the Consult PC and update the system.
