Record FREEZE FRAME DATA on the repair order, then go to the next step.
2
VERIFY RELATED SERVICE INFORMATION AVAILABILITY
•  Verify related Service Information availability.
•  Is any related Service Information available?
Yes
Perform repair or diagnosis according to the available Service Information.
•  If the vehicle is not repaired, go to the next step.
No
Go to the next step.
3
INSPECT GENERATOR CONNECTOR FOR POOR CONNECTION

Yes
Repair or replace suspected part, then go to Step 10.
No
Go to the next step.
4
INSPECT GENERATOR CIRCUIT FOR SHORT TO POWER SUPPLY
•  Generator connector is disconnected.
•  Turn the ignition switch to the ON position (engine off).
•  Measure the voltage between generator terminal LI (wiring harness-side) and body ground.
•  Is the voltage B+?
Yes
Repair or replace suspected part, then go to Step 10.
No
Go to the next step.
5
INSPECT GENERATOR CIRCUIT FOR SHORT TO GROUND
•  Generator connector is disconnected.
•  Inspect for continuity between generator terminal LI (wiring harness-side) and body ground.
•  Is there continuity?
Yes
Repair or replace suspected part, then go to the next step.
No
Go to the next step.
6
INSPECT PCM CONNECTOR FOR POOR CONNECTION
•  Turn the ignition switch off.
•  Inspect for poor connection (such as damaged/pulled-out terminals, corrosion).
•  Are there any malfunction?
Yes
Repair or replace suspected part, then go to Step 10.
No
Go to the next step.
7
INSPECT GENERATOR CIRCUIT FOR OPEN CIRCUIT
•  Generator and PCM connectors are disconnected.
•  Inspect for continuity between generator terminal LI (wiring harness-side) and PCM terminal 1O (wiring harness-side)
•  Is there continuity?
Yes
Go to the next step.
No
Repair or replace suspected part, then go to Step 10.
8
INSPECT BATTERY POSITIVE TERMINAL FOR POOR INSTALLATION
•  Turn the ignition switch off.
•  Inspect the battery positive terminal for looseness.
•  Is there any malfunction?
Yes
Connect the battery positive terminal correctly, then go to Step 10.
No
Go to the next step.
9
INSPECT GENERATOR
•  Inspect the generator.
•  Is there any malfunction?
Yes
Replace the generator, then go to the next step.
No
Go to the next step.
10
VERIFY TROUBLESHOOTING OF DTC P065B:00 HAS BEEN COMPLETED
•  Verify that all disconnected connectors reconnected.
•  Clear the DTC from the PCM memory using the M-MDS.
•  Perform the KOEO or KOER self-test.
•  Is the PENDING CODE for this DTC present?
Yes
Repeat the inspection from Step 1.
•  If the malfunction recurs, replace the PCM.
Go to the next step.
No
Go to the next step.
11
VERIFY AFTER REPAIR PROCEDURE
