DIAGNOSTIC PROCEDURE 3
Check “S” Terminal Circuit
1. CHECK “S” TERMINAL CONNECTION
1. Turn ignition switch OFF.
2. Check if “S” terminal is clean and tight.
OK or NG
OK >> GO TO 2.
NG >> Repair “S” terminal connection. Confirm repair by performing complete Starting/Charging system
test. Refer to Technical Service Bulletin.
2. CHECK “S” TERMINAL CIRCUIT
1. Disconnect alternator connector.
2. Check voltage between alternator harness connector and
ground.
OK or NG
OK >> Go to SC-22, "Trouble Diagnoses with Starting/Charging
System Tester (Charging)" .
NG >> Harness for open between alternator and fuse.
DIAGNOSTIC PROCEDURE 4
Check “B” Terminal Circuit
1. CHECK “B” TERMINAL CONNECTION
1. Turn ignition switch OFF.
2. Check if “B” terminal is clean and tight.
OK or NG
OK >> GO TO 2.
NG >> Repair “B” terminal connection. Confirm repair by performing complete Starting/Charging system
test. Refer to Technical Service Bulletin.

Removal and Installation NKS0000H
REMOVAL
1. Open the driver and front passenger window, and then disconnect the battery cable from the negative ter-
minal.
CAUTION:
Before disconnecting the battery, lower both the driver and passenger windows. This will prevent
any interference between the window edge and the vehicle when the door is opened/closed. Dur-
ing normal operation, the window slightly raises and lowers automatically to prevent any window
to vehicle interference. The automatic window function will not work with the battery discon-
nected.
2. Remove engine undercover, using power tools.
3. Remove air cleaner assembly and harness clip. Refer to EM-15, "
AIR CLEANER AND AIR DUCT" .
4. Remove radiator cooling fan assembly. Refer to CO-21, "
COOLING FAN" .
5. Remove alternator and power steering oil pump belt. Refer to EM-12, "
Removal and Installation" .
6. Disconnect alternator connector (1).
7. Remove “B” terminal mounting nut (2).
8. Remove the harness bracket bolts (A).
