1.

PRECONDITIONING

• Before inspecting the high-voltage system or disconnecting the low voltage connector of the inverter with

converter assembly, take safety precautions such as wearing insulated gloves and removing the service

plug grip to prevent electrical shocks. After removing the service plug grip, put it in your pocket to prevent

other technicians from accidentally reconnecting it while you are working on the high-voltage system.

• After disconnecting the service plug grip, wait for at least 10 minutes before touching any of the high-voltage

connectors or terminals.

• Waiting for at least 10 minutes is required to discharge the high-voltage capacitor inside the inverter with

converter assembly.

• If the battery voltage is applied to terminal +B, +B2, or MREL of the hybrid vehicle control ECU, even though

the ignition switch OFF, the circuit is shorted to +B.

>> GO TO 2.

2.

INSPECT RELAY (IGCT RELAY)

1. Remove the IGCT relay.

2. Measure the resistance according to the value(s) in the table below.

OK or NG

OK

>> GO TO 3.

NG

>> Replace IGCT relay.

3.

CHECK HARNESS AND CONNECTOR (HYBRID VEHICLE CONTROL ECU - HIGH VOLTAGE FUSE AND

FUSIBLE LINK BOX)

1. Disconnect the E66 hybrid vehicle control ECU connector.

2. Remove the IGCT relay from the high voltage fuse and fusible link box.

3. Turn ignition switch ON.

4. Measure the voltage according to the value(s) in the table below.

NOTE:

Turn ignition switch ON with the hybrid vehicle control ECU connectors disconnected causes other DTCs

to be stored. Clear the DTCs after performing this inspection.

DTC No.
