DTC SUMMARY MALFUNCTION DESCRIPTION These DTCs indicate an abnormal resolver output signal. The cause of this malfunction may be one of the following: Internal inverter malfunction
- Inverter with converter assembly internal circuit malfunction
Inverter low-voltage circuit malfunction
- The connectors are not connected properly
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. DESCRIPTION

Master Warning Light: Comes on |
P0C6916 | Generator Position Sensor Circuit "B" Circuit Voltage Below Threshold |
The value of the generator resolver cos phase signal is lower than the low side threshold.
(1 trip detection logic) |
- Inverter with converter assembly
- Wire harness or connector
| Comes on |
Master Warning Light: Comes on |
P0C6917 | Generator Position Sensor Circuit "B" Circuit Voltage Above Threshold |
The value of the generator resolver cos phase signal is higher than the high side threshold.

Master Warning Light: Comes on | MONITOR DESCRIPTION
The
motor generator control ECU monitors the Generator resolver output
signal. If the motor generator control ECU detects output signals that
are out of the normal range or specification, it will conclude that
there is a malfunction in the Generator resolver. If a malfunction is
detected, the motor generator control ECU will illuminate the MIL and
set a DTC. MONITOR STRATEGY

HINT:
- After repair has been completed, clear the DTC and then check that the
vehicle has returned to normal by performing the following All Readiness
check procedure.
Click here
- When clearing the permanent DTCs, refer to the "CLEAR PERMANENT DTC" procedure.
Click here
- Connect the Techstream to the DLC3.
- Turn the power switch on (IG) and turn the Techstream on.
- Clear the DTCs (even if no DTCs are stored, perform the clear DTC procedure).
- Turn the power switch off and wait for 2 minutes or more.
- Turn the power switch on (IG) and turn the Techstream on.
- With power switch on (IG) and wait for 5 seconds or more. [*1]
- Turn the power switch on (READY) and wait for 5 seconds or more. [*2]
- Depress the accelerator pedal of the vehicle with the engine stopped and the shift lever in P to start the engine. [*3]
- Drive the vehicle forward with the shift lever in D for 5 m (16 ft.) or more. [*4]
- Drive the vehicle backward with the shift lever in R for 5 m (16 ft.) or more. [*5]
HINT:
[*1] to [*5]: Normal judgment procedure.
The normal judgment procedure is used to complete DTC judgment and also used when clearing permanent DTCs.
- Enter the following menus: Powertrain / Motor Generator / Utility / All Readiness.
- Check the DTC judgment result.
HINT:
- If the judgment result shows NORMAL, the system is normal.
- If the judgment result shows ABNORMAL, the system has a malfunction.
- If the judgment result shows INCOMPLETE or N/A, perform the normal judgment procedure again.
CAUTION / NOTICE / HINT
CAUTION:
NOTICE: After
turning the power switch off, waiting time may be required before
disconnecting the cable from the negative (-) auxiliary battery
terminal. Therefore, make sure to read the disconnecting the cable from
the negative (-) auxiliary battery terminal notices before proceeding
with work. Click here
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.
