NOTE
1. Codes indicated by the * symbol are displayed, if the conditions are satisfied, even if the system is
normal. In either case, the system is normal if it can be reset. If ther\
e is an automatic cancellation not
intentionally made by the driver, however, excluding cancellations explicitly made by the
cancel
procedure, there may be a temporary malfunction such as poor contact of \
a harness connector even
though the system can be reset, and for that reason it is necessary to c\
heck according to each individual check chart that is applicable.

9. DISCONNECTION OF AUTOMATIC TRANSAXLE OIL
COOLER HOSES
Use a plug or otherwise cover the hose and nipple part of
the radiator so that dust, dirt, foreign materials, etc. do not enter after the hose has been disconnected from the
radiator.
INSPECTION
MWQCAN
a Check for foreign material between radiator fins.
l Check the radiator fins for bent, or damage.
l Check the radiator for corrosion, damage, rust or scale.
aCheck the radiator hoses for cracks, damage or deteriora-
tion.
l Check the reserve tank for damage.
lCheck the automatic transaxle oil cooler hoses for cracking,
damage or deterioration.
RADIATOR FAN MOTOR INSPECTION
(1) Check to be sure that the radiator fan rotates when battery voltage is applied between terminals (as shown in the
figure).
(2) Check to see that abnormal noises are not produced,
while motor is turning.
