1. Error Code
DCCT sensor circuit fault (Detail code118)
2. Error definition and error detection method
When an error value is detected with the DCCT detection circuit just before the inverter starts
3. Cause, check method and remedy
Refer to section -6- "Inverter (TJMU-A)" under part [4] Troubleshooting Principal Parts for error codes related to the
inverter.(page 251)
1. Error Code
Open-circuited IPM/Loose ACCT connector (Detail code 119)
2. Error definition and error detection method
Presence of enough current cannot be detected during the self-diagnostic operation immediately before inverter startup.
3. Cause, check method and remedy
P72 model
P96, P120, P144 models
Refer to section -6- "Inverter (TJMU-A)" under part [4] Troubleshooting Principal Parts for error codes related to the
inverter.(page 251)
5301 (TJMU-A) (P96, P120, P144 models only)
Cause Check method and remedy
(1) Contact failure Check for good contact of the INV board connector CNCT and the connec-
tor on the DCCT side.
(2) INV board failure Refer to IX [4] -6- (2) [1], [3], [4].(page 253)
(3) DCCT sensor failure Replace the DCCT sensor.
(4) Compressor failure Refer to IX [4] -6- (2) [2].(page 253)
(5) Inverter failure Refer to IX [4] -6-.(page 251)
5301 (TJMU-A)
Cause Check method and remedy
(1) Inverter output wiring problem Check output wiring connections.
Confirm that the U- and W-phase output cables are put through CT12
and CT22 on the INV board respectively.
(2) Inverter failure Refer to IX [4] -6- (2) [3], [4].(page 254)
(3) Compressor failure Refer to IX [4] -6- (2) [2].(page 253)
Cause Check method and remedy
(1) ACCT sensor disconnection Check the connection of the connector (CNCT2) on the INV board.
Check for proper mounting of ACCT.
(2) ACCT sensor failure Refer to IX [4] -6- (4).(page 257)
(3) Inverter failure Refer to IX [4] -6- (2) [3], [4].(page 254)
(4) Compressor failure Refer to IX [4] -6- (2) [2].(page 253)
