Open in rear motor resolver cos phase signal circuit (1 trip detection logic) |
| Comes on |
Master Warning: Comes on |
SAE Code: P0C5F |
|
P0C5F1F | Drive Motor "B" Position Sensor Circuit "B" Circuit Intermittent |
Open in rear motor resolver cos phase circuit detected when DTC P0C7917, P0E5717, P0D3319, P1C5D19, P1C5F19 or P1C5E19 is stored. (1 trip detection logic) |
| Does not come on |
Master Warning: Does not come on |
SAE Code: P0C63 |
HINT:
If either of these DTCs is output, an open in the indicated circuit (sin or cos phase circuit) is suspected.
MONITOR DESCRIPTION
The motor generator control ECU monitors the rear motor 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 rear motor resolver. If a malfunction is detected, the motor generator control ECU will illuminate the MIL and store a DTC.

CONFIRMATION DRIVING PATTERN
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
- Clear the DTCs (even if no DTCs are stored, perform the clear DTC procedure).
- Turn the ignition switch off and wait for 2 minutes or more.
- Turn the ignition switch to ON and wait for 5 seconds or more. [*1]
- Turn the ignition switch to 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, perform the normal judgment procedure again.

NOTICE:
- After the ignition switch is turned off, there may be a waiting time before disconnecting the negative (-) auxiliary battery terminal.

- When disconnecting and reconnecting the auxiliary battery.
HINT:
When disconnecting and reconnecting the auxiliary battery, there is an automatic learning function that completes learning when the respective system is used.

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.
- P0C5513, P0C551F, P0C5F13 or P0C5F1F may be output as a result of the malfunction indicated by the DTCs in table below.
- The chart above is listed in inspection order of priority.
- 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.)
