Inspection procedure 20
Idling speed is improper when A/C is operating
Probable cause
If the engine-ECU detects that the air conditioner is on, it activates the throttle control
servo to control idle-up operation.
The A/C-ECU judges if theloadcaused by air conditioner operation ishigh or low,
and converts it to voltage signal (high or low voltage) and inputs the signal to the
engine-ECU.
Based on this voltage signal, the engine-ECU controls the idle-up speed (forhigh
or low load).DMalfunction of the A/C control system
DImproper connector contact,opencircuit or
short-circuited harness wire
DMalfunction of the engine-ECU

CHARGING
1. Remove the battery from the vehicle.
2. The normal charging current is a value in amperes which is 1/10th of the battery capacity. If the
battery needs to be charged rapidly because of reasons such as time limitations, the maximum charging
current for rapid charging is the battery capacity expressed as an ampere value.
Battery typeCapacity (5-hour rate)Normal charging currentRapid charging current
75D2354 A5.4 A54 A
80D2658 A5.8 A58 A
95D3170 A7.0 A70 A
3. Determine when charging is finished.
DWhen the specific gravity of the battery electrolyte is constantly within 1.250 - 1.290 for a continuous
period of one hour or more
DWhen the voltage per cell during charging is 2.5 - 2.8 V constantly for a continuous period of one hour
or more
Caution
1. The battery plugs should be removed during charging.
2. The battery electrolyte level may rise and overflow from the battery during charging.
3. Explosions may occur if the battery is brought close to naked flames during charging.
4. Be careful to avoid tasks that might produce sparks or other danger while the battery is charging.
5. After charging is complete, replace the battery plugs, pour water over the battery to rinse
away any sulphuric acid, and let the battery stand to dry.
6. Charge the battery in a well-ventilated location.
7. Do not let the battery electrolyte temperature rise above approximately 45
°C (approximately
55
°C during rapid charging).

Re-test
OK
Normal
(1) Connect a battery tester to the battery.

(3) After measuring the battery voltage after 15 seconds,
remove the loadcurrent.
(4) Compare the measurement value with the specified
minimum voltage.(Refer to Table 2.)
OK:Higher than the minimum voltage
Measure the battery discharge voltage.
OK:12.4 V or more (specific gravity 1.240)NGCharge the battery at 5 A (constant current charging). (Refer
to Table 1.)
(1) Turn on the headlamps for 15 seconds.
(2) Turn off the headlamps and let the battery stand for 2
minutes to allow the battery voltage to stabilise.
(3) Disconnect the battery cables.

OPERATION
BUZZER
Light Reminder Warning Buzzer Function
When the driver’s door is opened with lighting switch
in the ON (tail lamp switch or headlamp switch)
position and ignition switch in the LOCK (OFF) or
ACC position, the buzzer will sound continuously to
remind the driver that the lamps (tail lamps or
headlamps) are ON.
This function does not work if the lighting switched
off through the headlamp automatic shutdownfunction. In addition, the ignition key reminder
warning buzzer function has a priority over this
function.
Center Display Operation Annunciation
Function
On vehicles with center display, the buzzer (peeps)
sounds when the operation switch of the audio
and navigation system is pressed.
CENTRAL DOOR LOCKING SYSTEM
Central Door Locking System Operation
When the lock switch is turned ON after the unlock
switch on the driver’s door lock actuator switch
is OFF, the ETACS-ECU gives a lock output for
0.5 second. When the unlock switch is turned ON
after the lock switch on the driver’s door lock
actuator switch is OFF, the ETACS-ECU gives an
unlock output for 0.5 second.
When the front passenger’s door key or back door
key is operated, the ETACS-ECU gives a lock or
unlock output for 0.5 second.Forgotten Key Prevention Function
If, with the key reminder switch OFF and the driver’s
door switch ON, the driver’s door lock switch is
turned ON after the door unlock switch in the front
door lock actuator is turned OFF, the ETACS-ECU
waits 0.3 second then give an unlock relay output
for 0.5 second, there by preventing the doors from
being locked. This operation prevents the ignition
key from being locked inside the vehicle. This
function takes precedence over the central door
locking control function.

HEADLAMP WASHER
If the headlamp washer switch at the steering
column is placed in the ON position when the ignition
switch is in the ACC or ON position and theheadlamp switch is in the ON position, the headlamp
washer drive signal is turned ON for 0.5 second.
IGNITION KEY HOLE ILLUMINATION LAMP
When the ignition switch is turned to LOCK (OFF) or
ACC position with the driver’s door opened, the
ignition key hole illumination lamp is illuminated.
If the door is closed in that state, the lamp goes out
after 30 seconds. Vehicles with keyless entrysystem, it illuminates for 30 seconds after the
ignition key is removed. In either case the lamp goes
out when the ignition switch is turned to ON position.
HEADLAMP
Headlamp Automatic Shutdown Function
If the ignition switch is turned to LOCK (OFF) or
ACC position, when the headlamps are on, the
headlamps will be switched off in three minutes.
If the driver’s door is opened within that three-minute
period, the headlamps will be switched off
automatically. This prevents the battery from
discharged.
In addition, if the headlamps are turned on when
the ignition switch is at LOCK (OFF) or ACC position,
the headlamps will not be switched off.Headlamp Dimmer Switch Automatic Reset
Function
This function allows the dimmer switch to be reset
to the low-beam position whenever the headlamp
switch is turned ON.
Daytime Running Lamp (DRL) Function
If the ignition switch is turned to ON when the
headlamps and tail lamps are off, the headlamps
(low-beam) and tail lamps turn on.
FLASHER TIMER
Turn-signal Lamp
When the ignition switch is turned to ON position
and turn-signal lamp switch is placed in the ON
position for right or left turn signaling, the system
generates turn-signal lamp drive signals (flashing
signals).
The system also notifies of a blown turn-signal lamp
bulb by shortening the flashing intervals of the
corresponding indicator lamp.Hazard Warning Lamp
The system detects a change from ON to OFF
of the hazard lamp input signal and activates the
hazard lamps if they are not in operation or
deactivates the lamps if they are operating (reversal
of state between activation and deactivation).
FRONT FOG LAMP
If the front fog lamp switch is turned ON at the
condition that the headlamp or the tail lamp is turned
ON (including the illumination by the automatic
lighting function), the front fog lamp is turned ON.Whenever the tail lamps are turned on at the next
time, the front fog lamps will always be off regardless
of the switch positions. In addition, if the tail lamp
is switched off by the automatic lighting system,
the front fog lamp will also be switched off. However,
the front fog lamp will be illuminated when the tail
lamp is switched on.
