Nissan Note — проверка темного тока в системе зарядки автомобиля [30/60]

SC-30

CHARGING SYSTEM

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-31, "

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-31,

"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.

NOTE:

If dark current is greatly reduced when removing the fuse, and even if dark current is not greatly increased

when installing it again, the fuse circuit may be the cause.

6. Check that dark current changes when moving the suspect circuit harness. If dark current changes, check

harness for short. If dark current does not change, electronic unit in the circuit may not be entering the

energy-saving mode when it turns OFF. If it does not enter the energy-saving mode, replace electronic

unit.

7. No malfunction for alternator and electrical equipment. Electric load may be larger than alternator generat-

ing ability. Check the customer's usage.
