NOTE: The voltage waveform of the alternator "B" terminal can
undulate as shown at left. This waveform is produced when the
regulator operates according to fluctuations in the alternator
load (current), and is normal for the alternator.
If the ripple height is abnormally high (approximately 2 V or
more during idling), the wires between the alternator "B" termi-
nal and the battery have broken due to fuse blowing, etc. The
alternator is usually operating properly.
.
ABNORMAL WAVEFORMS EXAMPLES
NOTE: The size of the waveform patterns can differ greatly,
depending on the adjustment of the variable knob on the oscil-
loscope.
NOTE: Identification of abnormal waveforms is easier when
there is a large output current (regulator is not operating).
(Waveforms can be observed when the headlights are illumi-
nated.)
NOTE: Check the conditions of the alternator malfunction light
(illuminated/not illuminated) also, and carry out a total check.

rates lock button, unlock button, trunk button and
panic button .
When the transmitter unlock button is pressed
once, the driver's door will be unlocked. If the but-
ton is pressed twice, all the doors will be

back function will work as follows:
The answerback operation can be altered as fol-
lows:NOTE: Enabling/disabling the hazard warning
light flashing, the horn sounding in accordance
with the answerback function. For further details
on using the transmitter to adjust answerback,

FUNCTION
BGBDGCGD
When the doors are locked or unlocked by using the transmit-
ter, the dome light will flash/illuminate, the turn-signal lights will
flash (hazard answerback), or the horn will sound (horn

PRECAUTIONS BEFORE SERVICE
GENERAL00-24
SERVICING ELECTRICAL SYSTEMM1001011900057
Battery posts, terminals and related accessories con-
tain lead and lead compounds. WASH HANDS AFTER
HANDLING.
1. Note the following before proceeding with working on the
electrical system.
Never perform unauthorized modifications to any electrical
device or wiring. Such modifications might lead to a vehicle
malfunction, over-capacity or short-circuit that could result in
a fire in the vehicle.
Before connecting or disconnecting the negative bat-
tery cable, be sure to turn the ignition switch to the
"LOCK" (OFF) position and turn off the lights (If this is
not done, there is the possibility of semiconductor
parts being damaged).
After completion of the work (and the negative battery
terminals is connected), warm up the engine and allow
it to idle for approximately 10 minutes under the condi-
tions described below in order to stabilize engine con-
trol conditions, and then check to be sure that the idle
is satisfactory.
Engine coolant temperature: 85 to 95C (185 to
203
F)
Lights and all accessories: OFF
Transaxle: "N" or "P" position
Steering wheel: straight-forward position
2. When servicing the electrical system, disconnect the
negative cable terminal from the battery.
VEHICLE WASHINGM1001012000057
If high-pressure car-washing equipment or steam car-washing
equipment is used to wash the vehicle, be sure to maintain the
spray nozzle at a distance of at least approximately 50 cm (20
inches) from any plastic parts and all opening parts (doors, lug-
gage compartment, etc.).

EMISSION CONTROL
ENGINE AND EMISSION CONTROL17-83
Required Special Tool:
MB995061: Purge Flow Indicator
1. Disconnect the purge hose from the evaporative emission
(EVAP) purge solenoid, and connect special tool MB995061
between the EVAP purge solenoid and the purge hose.
2. Before inspection, set the vehicle in the following conditions:
Engine coolant temperature: 80 95C (176 203F)
Lights, electric cooling fan and accessories: OFF
Transaxle: P range
3. Run the engine at idle for more than four minutes.
4. Check the purge flow volume when engine is revved
suddenly several times.
Standard value: Momentarily 20 cm
3/s (2.5 SCFH) or
more.
5. If the purge flow volume is less than the standard value,
check it again with the vacuum hose disconnected from the
EVAP canister. If the purge flow volume is less than the
standard value, check the vacuum port and the vacuum
hose for clogging. Also check the EVAP purge solenoid. If
the purge flow volume is at the standard value, replace the
EVAP canister.
EVAPORATIVE EMISSION PURGE SOLENOID
CHECK
M1173001700289
1. Disconnect the vacuum hose (black, black with red paint
mark) from the evaporative emission (EVAP) purge
solenoid.
NOTE: When disconnecting the vacuum hose, always place
an identification mark so that it can be reconnected at its
original position.
2. Disconnect the harness connector.
3. Connect a hand vacuum pump to nipple (A) of the EVAP
purge solenoid (refer to the illustration at left).
4. As described in the chart below, check airtightness by
applying a vacuum with voltage applied directly from the
battery to the EVAP purge solenoid valve and without
applying voltage.
