Troubleshooting Procedure
Step Actions and Questions Yes No
1. Check the HVPS2 Fan operation.
Perform DC330 Component Control on
page 2-26 [042-005] to check the rotation of the
HVPS2 Fan.
Is the Fan working properly?
Replace the MCU PWB
(REP 12.4 MCU PWB
on page 4-206).
Go to step 2.
2. Check the installation of the HVPS2 Fan (REP
12.2 HVPS2 Fan on page 4-203).
Manually rotate the HVPS2 Fan.
Does the Fan rotate?
Reinstall the HVPS2
Fan.
Go to step3.
3. Check the connection between the HVPS2 Fan
and MCU PWB.
Are the connectors P/J468, P/J4681, and
P/J4683A connected securely?
Go to step 4. Connect the
connectors P/J468,
P/J4681, and
P/J4683A.
4. Check the conductivity between the HVPS2 Fan
and Relay Connector.
Is the connection between P/J4683A <=>
P/J4681 conducting properly?
Go to step 5. Replace the Top
Harness Assembly.
