On Board Diagnosis Logic
UBS00DWJ
This diagnosis checks whether the engine coolant temperature is extraordinary high, even when the load is
not heavy.
This self-diagnosis has one trip detection logic.
CAUTION:
When a malfunction is indicated, be sure to replace the coolant. Refer to
. Also, replace the engine oil. Refer to
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-14, "ANTI-FREEZE COOLANT MIXTURE
2.
After refilling coolant, run engine to ensure that no water-flow noise is emitted.
Overall Function Check
UBS00DWK
Use this procedure to check the overall function of the engine coolant over temperature enrichment protection
check, a DTC might not be confirmed.
WARNING:
Never remove the radiator cap when the engine is hot. Serious burns could be caused by high-pres-
sure fluid escaping from the radiator.
Wrap a thick cloth around the cap. Carefully remove the cap by turning it a quarter turn to allow built-
up pressure to escape. Then turn the cap all the way off.
WITH CONSULT-II
1.
Check the coolant level and mixture ratio (Using coolant tester)
in the reservoir tank and radiator.
Allow engine to cool before checking coolant level and mix-
ture ratio.
●
If the coolant level in the reservoir and/or the radiator is below
the proper range, skip following steps and go to
●
If the coolant mixture ratio is out of range between 45 to 55%,
replace the coolant. Refer to
–
Fill radiator with coolant up to specified level with a filling
speed of 2 liters per minute like pouring coolant by kettle. Be
sure to use coolant with the proper mixture ratio. Refer to
MA-14, "ANTI-FREEZE COOLANT MIX-
–
After refilling coolant, run engine to ensure that no water-flow noise is emitted.
DTC No.

After checking or replacing coolant, go to step 3) below.
2.
Confirm whether customer filled the engine coolant or not. If customer filled the engine coolant, skip fol-
lowing steps and go to
EC-1454, "Diagnostic Procedure"
3.
Start engine and make sure that cooling fan (crankshaft driven) operates. If NG, go to After repair, go to
next step.
4.
Check for blocked coolant passage.
Warm up engine to normal operating temperature, then grasp upper and lower radiator hoses and make
sure that coolant flows.
If NG, go to step 4 of
EC-1454, "Diagnostic Procedure"
. After repair, go to next step.
Be extremely careful not to touch any moving or adjacent parts.
5.
Check radiator for blocked air passage
Check for blocked condenser or radiator (condenser or radiator fins damaged, condenser or radiator
clogged), after market fog lamps ...etc. Check for condenser or radiator fin damage, shroud damage, vehi-
cle front end for clogging of debris or insects ...etc.
Check for improper fitting of front end cover, damaged radiator grille or bumper, vehicle frontal area dam-
aged by collision but not repaired.
If NG, take appropriate action and then go to next step.
6.
Check ECT sensor for proper operation. Refer to step 5 of
EC-1454, "Diagnostic Procedure"
. If NG,
replace ECT sensor and go to next step.
7.
Check ignition timing. Refer to
Make sure that ignition timing is 10
° ± 5° at 700 ± 50 rpm.
If NG, adjust ignition timing and then recheck.
