HYBRID / BATTERY CONTROL HYBRID CONTROL SYSTEM P1CE213 PCU Interlock Circuit Open P1CE292 PCU Interlock Performance or Incorrect Operation
DTC SUMMARY
MALFUNCTION DESCRIPTION
The hybrid vehicle control ECU detects that a safety device (interlock) is operated or that there is an open circuit in the detection circuit. (Even if an open circuit occurs while the vehicle is stopped, the system determines that the safety device was operated.)
The cause of this malfunction may be one of the following:
Inverter with converter assembly malfunction
MG ECU malfunction
Inverter with converter assembly malfunction
CAN communication error between the MG ECU and hybrid vehicle control ECU
INSPECTION DESCRIPTION
| System Diagram Location | Inspection Content | Reason |
|---|---|---|
| *a | Check whether the safety device (interlock) is connected securely and installed properly (inverter cover). | DTC output due to improper connection or forgetting to install parts. |
| *b | Inspect the detection circuit. | DTC output due to an open circuit or improper connection (dirt, foreign matter, etc.). |
DESCRIPTION
Refer to the description for DTC P0A0A13.

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.
Connect the GTS to the DLC3.
Turn the ignition switch to ON and turn the GTS on.
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 turn the GTS on.
With ignition switch ON and wait for 5 seconds or more.
Enter the following menus: Powertrain / Hybrid Control / 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 driving pattern again.

CAUTION / NOTICE / HINT
- CAUTION:
-
Refer to the precautions before inspecting high voltage circuit.
- NOTICE:
- ·
After removing the service plug grip, do not turn the ignition switch to ON (READY), unless instructed by the repair manual because this may cause a malfunction.
·As interlock circuit DTCs or other DTCs may be stored when the ignition switch is turned to ON in the following procedure, make sure to clear the DTCs after inspection.
·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:
- ·
P1CE213 or P1CE292 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.)
