Diagnostic Trouble Code (DTC) Detecting Criteria
GENERAL DESCRIPTION
CQ:DTC P0483 COOLING FAN RATIONALITY CHECK
1. OUTLINE OF DIAGNOSIS
Detect the function abnormality of the radiator fan.
Judge as NG when the engine coolant temperature slowly decreases even when the radiator fan is rotating.
2. ENABLE CONDITIONS
Diagnostic enable condition is established if the radiator fan changes from OFF → ON when all of the con-
ditions below are met.
When one of the conditions below is not met, the diagnostic enable condition is not established.
3. GENERAL DRIVING CYCLE
Perform the diagnosis continuously when the radiator fan changes from OFF → ON when idling.
4. DIAGNOSTIC METHOD
Abnormality Judgment
Judge as NG when the continuous time of completing the malfunction criteria below becomes more than 5
minutes.
Time Needed for Diagnosis: 5 minutes
Malfunction Indicator Light Illumination: Illuminates when malfunctions occur in 2 continuous driving cy-
cles.
Normality Judgment
Judge as OK and clear the NG when the malfunction criteria below are met.
5. DTC CLEAR CONDITION
•When the OK idling cycle is completed 40 times in a row
•When “Clear Memory” is performed
6. MALFUNCTION INDICATOR LIGHT CLEAR CONDITIONS
•When the OK driving cycle is completed 3 times in a row
•When “Clear Memory” is performed
7. FAIL SAFE
None
8. ECM OPERATION AT DTC SETTING
Memorize the freeze frame data. (For test mode $02)
Secondary Parameters Enable Conditions
Engine speed 500 — 900 rpm

4. DIAGNOSTIC METHOD
Abnormality Judgment
Judge as NG when the continuous time of completing the malfunction criteria below becomes more than 2.5
seconds.
Time Needed for Diagnosis: 2.5 seconds
Malfunction Indicator Light Illumination: Illuminates when malfunctions occur in 2 continuous driving cy-
cles.
Normality Judgment
Judge as OK and clear the NG when the malfunction criteria below are met.
5. DTC CLEAR CONDITION
