HINT:

If any of these DTCs is output, a malfunction of the MG ECU circuit board or poor installation of a low voltage connector is suspected. It is not necessary to inspect the motor resolver.

Refer to the system description for the Generator Resolver Circuit.

HINT:

·

If the problem symptom cannot be reproduced, performing a road test on a road on which the vehicle tends to vibrate will make it easier to reproduce the symptom.

·

If the resolver is malfunctioning, the vehicle may not drive smoothly.

·

When inspecting the connectors, if it is difficult to judge if a connector was disconnected, deformed or improperly secured, disconnect and reconnect the connector and then check for DTCs again. Check if the same DTC is output. If the same DTC is not output, improper connection of connectors is suspected.

·

As a malfunction detection threshold may be exceeded when performing the vibration or heat connector inspections, make sure to perform the following inspection to check that the DTC was not stored due to the malfunction of a part.

·

P0C6416, P0C6417, P0C6916 or P0C6917 may be output as a result of the malfunction indicated by the DTCs in table below.

(a)

The chart above is listed in inspection order of priority.

(b)

Check DTCs that are output at the same time by following the listed order. (The main cause of the malfunction can be determined without performing unnecessary inspections.)
