6.Check for a poor connection at the battery terminal.
Check for a broken drive belt (see page 4-30).
Test the battery (see page 22-67).
Troubleshoot the alternator and regulator circuit
(see page 4-28).
Check the drive belt auto-tensioner (see page 4-31).
Check for excessive parasitic electrical current draw
with the ignition switch to LOCK (0), and the key
removed. The multiplex control unit may take up to 10
minutes to turn off (sleep mode) for same models.

13. Check for continuity between ECM/PCM connector terminal B41 and alternator 4P connector terminal
No. 2.
Replace the alternator (see page 4-34), or
repair the alternator (see page 4-38).
Repair open in the wire between alternator 4P
connector terminal No. 2 and ECM/PCM connector
terminal B41. 1. Inspect the belt for cracks or damage. If the belt is
cracked or damaged, replace it (see page 4-31).
2. Check the position of the auto-tensioner indicator (A) is within the standard range (B) as shown. If it is
out of the standard range, replace the drive belt
(see page 4-31).

16. If you removed the pulley, put the rotor in the drive- end housing, then tighten its locknut to 110 N·m
(11.2 kgf·m, 81.0 lbf·ft).
17. Remove any grease or any oil from the slip rings.
18. Put the rear housing assembly and the drive-end housing/rotor assembly together, tighten the four
through bolts.
19. Push the brushes (A) in, then insert a pin or drill bit (B) (about 1.6 mm (0.06 in.) diameter) to hold them
there.
20. Install the brush holder assembly, and pull out the pin or drill bit.
21. Install the end cover.
22. After assembling the alternator, turn the pulley by hand to make sure the rotor turns smoothly and
without noise.
23. Install the alternator (see page 4-36) and the drive belt (see page 4-31).
