DescriptionECS0 04 U4
The torque converter clutch solenoid valve is activated, with the gear
in “D
4”, by the TCM in response to signals sent from the vehicle
speed and throttle position sensors. Lock-up piston operation will
then be controlled.
Lock-up operation, however, is prohibited when A/T fluid tempera-
ture is too low.
When the accelerator pedal is depressed (less than 2/8) in lock-up
condition, the engine speed should not change abruptly. If there is a
big jump in engine speed, there is no lock-up.

How to Handle BatteryEKS00313
CAUTION:
lIf it becomes necessary to start the engine with a booster battery and jumper cables, use a 12-volt
booster battery.
lAfter connecting battery cables, ensure that they are tightly clamped to battery terminals for good
contact.
lNever add distilled water through the hole used to check specific gravity.
METHODS OF PREVENTING OVER-DISCHARGE
The following precautions must be taken to prevent over-discharging a battery.
lThe battery surface (particularly its top) should always be kept
clean and dry.
lThe terminal connections should be clean and tight.
lAt every routine maintenance, check the electrolyte level.
This also applies to batteries designated as “low maintenance”
and “maintenance-free”.
lWhen the vehicle is not going to be used over a long period of
time, disconnect the negative battery terminal. (If the vehicle has
an extended storage switch, turn it off.)
lCheck the charge condition of the battery.
Periodically check the specific gravity of the electrolyte. Keep a
close check on charge condition to prevent over-discharge.
CHECKING ELECTROLYTE LEVEL
WA RN ING:
Do not allow battery fluid to come in contact with skin, eyes, fabrics, or painted surfaces. After touch-
ing a battery, do not touch or rub your eyes until you have thoroughly washed your hands. If acid con-
tacts eyes, skin or clothing, immediately flush with water for 15 minutes and seek medical attention.
