2.11.7.8 Generator Noise Diagnosis
Diagnostic Tips:Generator noise may be caused by electrical or mechanical noise. Electrical noise (electromagnetic hum sound) is
usually added to the generator with the electrical load changes, which is the normal operating characteristics of all generators. During
the service, pay attention to distinguish, otherwise it will cause unnecessary customer complaints. When diagnose the generator
mechanical noise, firstly check whether there are loose generator components or interference. In some cases even if the sound in
engine compartment is light, it can enter into the passenger compartment. If this is the case, replacing the generator does not solve
the problem, which leads to misjudgments.
Step 1
Keep the generator not working, and confirm whether the noise disappears.
(a)
Start the engine, verify that the noise can be heard.
(b)
Shut down the engine.
(c)
Disconnect the generator from the generator on the wiring
harness connector EN07.
(d)
Start the engine.
Confirm whether the noise disappears?
Yes

No
Step 2
Check the generator shaft.
(a)
Shut down the engine.
(b)
Remove the drive belt.
(c)
Rotate the generator pulley by hand.
Does the generator rotate smoothly without catching and
grinding noise?
Yes
No
Step 3
Reinstall the generator.
Remove and install the generator. Tighten the generator retaining
bolts to the specified torque. Refer to
. Start the engine, does the noise disappear?
Yes
System normal
No
Step 4
Is the drive belt loose?
Yes
No
Step 5
Compare with a known good vehicle, is the noise the same?
Yes
System normal
No
Step 6
Replace the generator.
Important Note
If a clear generator fault has not been found, make sure that all
other possible noise sources have been excluded and then replace
the generator.
If the noise is part of the normal generator characteristics, after
replacing generator the noise will not disappear.
Yes
Troubleshooting
Step 7
Replace the drive belt or the drive belt tensioner.
