- Disconnect the negative cable from the battery.
- Connect the negative cable again after connecting the ammeter.
How to check
Disconnect the cable connected to the
B terminal on the alternator. Connect
one end of the ammeter to the B
terminal and the other end to the cable
connected to the B terminal.
Measure the maximum output value.
(Maintain the engine speed between
2,500 and 3,000 rpm.)
(Turn the headlamp and all the electrical
switches on.)
Move the gear selector lever to the
neutral position.
Maintain the engine speed at 2,500 rpm
with the vehicle unloaded.
(Turn all the electrical switches off.)
Disconnect the negative cable from the
battery.
Remove the B terminal and turn off the
ignition switch.
Measure the resistance between the L
and F terminals with an ohmmeter.
Connect the B terminal wiring.
Measure the voltage with the engine
running.
DTC set value / Action
- Pass: If the measured current
is 45 A or higher.
- Fail: If the measured current
is less than 45 A.
- Check the current of the B
terminal.
- Open circuit: If the
measured current is 5 A or
higher.
- Pass: If the measured
resistance is between 3 and
6Ω.
- Faulty rotor coil or slip ring: If
the measured resistance is
less than 3Ω or greater than
6Ω.
- Specification: 12.5V to
14.5V
-
Faulty IC regulator or field
coil: If the measured
voltage is 14.5V or higher.
