If the radiator fan relay is normal, check the wiring for continuity, using the wiring diagram in this section.
Special Tool - Hand Tester: 57001-1394
If the wiring is good, check the ECU for its ground and power supply (see ECU Power Supply Inspection in the Fuel System (DFI) chapter).
If the ground and power supply are good, replace the ECU (see ECU Removal/Installation in the Fuel System (DFI) chapter).

Radiator Fan Relay Removal/InstallationAlternator Inspection
There are three types of alternator failures: short, open
(wire burned out), or loss in rotor magnetism. A short or
open in one of the coil wires will result in either a low output,
or no output at all. A loss in rotor magnetism, which may be
caused by dropping or hitting the alternator, by leav ...
Backups
The ECU takes the following measures to prevent engine damage when the
DFI, ignition, S-KTRC
or immobilizer system parts have troubles.
Note:
(1): D-J Method: When the engine load is light like at idling or low
speed, the ECU determines the
injection quantity by calculating fr ...
