1. Check for proper operation of the electrical load
detector (ELD) by checking the malfunction
indicator lamp (MIL) (see page 11-3). If a DTC is
present, diagnose and repair the cause before
continuing with this test.
2. Disconnect the alternator 4P connector from the
alternator.
3. Start the engine, and turn the headlights (high
beam) ON.
4. Measure voltage between the alternator 4P
connector terminal No. 2 and the positive terminal
of the battery.
Go to step 8.
Go to step 5.
5. Turn the headlight and ignition switch OFF.
6. Disconnect the powertrain control module (PCM)
connector C (31P) (1999-2000, 2002-2004 models)
or PCM connector B (24P) (2001 model).
7. Check for continuity between the PCM connector
terminal C2 (1999-2000, 2002-2004 models) or B6
(2001 model) and body ground.
Repair a short in the wire between the
alternator and PCM.
Substitute a known-good PCM, and recheck
(see page 11-5). If prescribed voltage is now
available, replace the original PCM
(see page 11-4).

8. Turn the headlight and ignition switch OFF.
9. Disconnect the negative cable from the battery.
10. Disconnect the PCM connector C (31P) (1999-2000,
2002-2004 models) or PCM connector B (24P) (2001
model) from the PCM.
11. Check for continuity between the PCM connector
terminal C2 (1999-2000, 2002-2004 models) or B6
(2001 model) and alternator 4P connector terminal
No. 2.
Repair the alternator components:
1999-2001 models (see page 4-32).
2002-2004 models (see page 4-38).
Repair an open in the wire between the
alternator and PCM.

1. Inspect the belt for cracks and damage. If the belt is
cracked or damaged, replace it.
2. Check that the pointer (A) on auto-tensioner
housing is not beyond the edge of the indicator rib
(B) on the tensioner base. If pointer is beyond the
indicator rib, replace the alternator-compressor
belt.
1. Inspect the belt for cracks and damage. If the belt is
cracked or damaged, replace it.
2. Check that the pointer (A) on the oil pump is not
beyond the edge of the indicator rib (B) on the auto-
tensioner. If pointer is beyond the indicator rib,
replace the alternator-compressor belt.
1. Remove the splash shield (2002-2004 models) (see
step 28 on page 5-6).
2. Move the auto-tensioner (A) to relive tension from
the alternator-compressor belt (B), and remove the
belt.
3. Install the new belt in the reverse order of removal.

1. Make sure you have the anti-theft code for the radio
and the navigation system, then write down the
frequencies for the radio’s preset buttons.
2. Disconnect the negative cable from the battery first,
then disconnect the positive cable.

4-26).
4. Disconnect the alternator 4P connector (A) and BLK
wire (B) from the alternator.
5. Remove the mounting bolt (A) and alternator
bracket mounting bolt (B), then remove the harness
clamp (C) from the alternator bracket.
6. Install in the reverse order of removal.
