CHARGING SYSTEM
INSPECTION OF INSUFFICIENT ALTERNATOR POWER GENERATION
CAUTION:
Check them using charged battery performed battery inspection.
1.VOLTAGE INSPECTION
1. Increase engine speed to 2,500 rpm.
2. Turn electrical load to ON. (Headlamp LO turns on, blower fan
motor maximum airflow amount)
3. Check battery voltage.
Is the inspection result 12.8V to 15.1V?
YES >> GO TO 2.
NO >> Replace alternator. (Alternator power generation error.)
2.CURRENT INSPECTION
1. Turn ignition switch OFF.
2. Disconnect the battery ground cable.
3. Attach current measurement probe for CONSULT-II to the harness for alternator terminal B.
(If the probe can not be attached properly, then connect the sub-
harness between alternator terminal B and the vehicle side har-
ness as shown in figure, and attach the probe to sub-harness.)
4. Connect battery ground cable.
5. Increase engine speed to 2,500 rpm.
6. Turn electrical load to ON. (Headlamp LO turns on, blower fan
motor maximum airflow amount, rear window defogger)
7. Check alternator terminal B current.
CAUTION:
Be careful of rotating parts because the engine is running.
Is the inspection result 30A or more?
YES >> GO TO dark current inspection. Refer toSC-21, "DARK CURRENT INSPECTION". (Alternator is
normal. Do not replace.)
NO >> Replace alternator. (Alternator power generation error.)
INSPECTION OF EXCESSIVE ALTERNATOR POWER GENERATION
1.ALTERNATOR VOLTAGE INSPECTION
1. Increase engine speed to 2,500 rpm.
2. Check battery voltage.
Is the inspection result 16V or less?
YES >> GO TO 2.
NO >> Replace alternator. (Excessive alternator power genera-
tion.)

FRONT WIPER AND WASHER SYSTEM
COMBINATION SWITCH READING FUNCTION
Description
lBCM reads combination switch status, and controls related systems such as headlamps and wipers,
according to the results.
lBCM reads information for a maximum of 20 switches by combining 5 output terminals (OUTPUT 1-5) and
5 input terminals (INPUT 1-5).
Operation Description
lBCM activates transistors of output terminals (OUTPUT 1-5) periodically, and allows current to flow in
turn.
lIf any (1 or more) switches are turned ON, the circuit of output terminals (OUTPUT 1-5) and input termi-
nals (INPUT 1-5) becomes active.
lAt this time, transistors of output terminals (OUTPUT 1-5) are activated to allow current to flow. When volt-
age of the input terminal (INPUT 1-5) corresponding to that switch changes, the interface in the BCM
detects a voltage change, and the BCM determines that the switch is ON.
