2. BATTERY VOLTAGE INSPECTION
1. Turn ignition switch OFF.
2. Disconnect alternator connector.
3. Turn ignition switch ON.
4. Check voltage between alternator connector terminal 4 and
ground.
Is the inspection result 12V or more?
YES >> Replace alternator. (Alternator power generation error)
NO >> GO TO 3.
3. CONNECTOR INSPECTION
1. Turn ignition switch OFF.
2. Check IPDM E/R and terminals (IPDM E/R side, and harness side) for damage, deformation or improper
connection.
OK or NG
OK >> GO TO 4.
NG >> Repair terminals and connectors.
4. CONTINUITY INSPECTION
1. Disconnect IPDM E/R connector.
2. Check continuity between IPDM E/R connector terminal 63 and alternator connector terminal 4.
OK or NG
OK >> Replace IPDM E/R. (Do not replace alternator, since it is normal.)
NG >> Repair the harnesses or connectors. (Do not replace alternator, since it is normal.)
DARK CURRENT INSPECTION
Dark Current: Small current while ignition switch is “OFF”.
NOTE:
If battery ground cable is disconnected from battery terminal, a large dark current may not be reproduced.
When battery discharge occurs, never disconnect battery terminal while using ammeter.
Do not connect CONSULT-II CONVERTER to data link connector when measuring dark current. CON-
SULT-II power should be supplied using AC adapter or internal battery.
1. Attach current measurement probe for CONSULT-II to battery
ground cable. Refer to SC-38, "
OPERATION PROCEDURE OF
CURRENT MEASUREMENT PROBE FOR CONSULT-II" .
2. Check that all electrical equipment is turned OFF.
3. Remove key. Close and lock doors. Check that room lamp turns
off.
4. Measure dark current. Is it 50mA or less? Refer to SC-38,
"OPERATION PROCEDURE OF CURRENT MEASUREMENT
PROBE FOR CONSULT-II" .
NOTE:
Dark current stable time is different due to equipment and use of
the vehicle. If it is not 50mA or less after leaving for 1 minute, measure dark current again after leaving for
30 minutes or more.
If YES, GO TO 7. If NO, GO TO 5.
5. Remove and install fuses one by one. Search for the fuse that greatly changes dark current.
4 - Ground : 12V or more

63 - 4 : Continuity should exist.
