CONSULT-II Reference Value in Data Monitor ModeINFOID:0000000001702930
Specification data are reference values.
On Board Diagnosis LogicINFOID:0000000001702931
If the cooling fan or another component in the cooling system malfunctions, engine coolant temperature will
rise. When the engine coolant temperature reaches an abnormally high temperature condition, a malfunction
is indicated.
This self-diagnosis has the one trip detection logic.
CAUTION:
When a malfunction is indicated, be sure to replace the coolant. Refer to CO-8, "
Changing Engine
Coolant". Also, replace the engine oil. Refer to LU-7, "Changing Engine Oil".
1. Fill radiator with coolant up to specified level with a filling speed of 2 liters per minute. Be sure to
use coolant with the proper mixture ratio. Refer to MA-11, "
Anti-freeze Coolant Mixture Ratio".
2. After refilling coolant, run engine to ensure that no water-flow noise is emitted.
Overall Function CheckINFOID:0000000001702932
Use this procedure to check the overall function of the cooling fan. During this check, a DTC might not be con-
firmed.
