CABLE, INTERLOCK SWITCH)
2. Relay Connector (9P) to DC Controller PCB (UN04/J133) (Unit of replacement: CABLE,
SENSOR)
- Harness between the Low Voltage Power Supply PCB (UN01/J315 and J322) and the DC
Controller PCB (UN04/J100 and J115) (Unit of replacement: POWER SUPPLY ASSEMBLY)
- Low Voltage Power Supply PCB (UN01) (Unit of replacement: POWER SUPPLY ASSEMBLY)
- DC Controller PCB (UN04) (Unit of replacement: DC CONTROLLER PCB ASSEMBLY)
[Remedy] Check/replace the related harness/cable, connector and parts.
[Reference] Before replacing the DC Controller PCB, back up the service mode data (approx. 2
min) and restore the backup data after the replacement so the data may be able to be protected.
