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:
INSPECTION DESCRIPTION
System Diagram Location | Inspection Content | Reason | Inspection Step |
---|---|---|---|
*a | Check whether the safety device (interlock) is connected securely and installed properly (inverter cover, etc.). | DTC output due to improper connection or forgetting to install parts. | 4 |
*b | Inspect the detection circuit. | DTC output due to an open circuit or improper connection (dirt, foreign matter, etc.). | 5 |

PROCEDURE
1. | CHECK DTC OUTPUT (HYBRID CONTROL, MOTOR GENERATOR) |
(a) Connect the Techstream to the DLC3.
(b) Turn the power switch on (IG).
(c) Enter the following menus: Powertrain / Hybrid Control and Motor Generator / Trouble Codes.
(d) Check for DTCs.
Powertrain > Hybrid Control > Trouble Codes Powertrain > Motor Generator > Trouble Codes Result | Proceed to |
---|---|
P1CE213 or P1CE292 only is output, or DTCs except the ones in the table below are also output. | A |
DTCs of hybrid control system in the tables below are output. | B |
DTCs of motor generator control system in the tables below are output. | C |

P1CE213 or P1CE292 is output again. | A |
Neither P1CE213 or P1CE292 is output again. | B |
HINT:
Check if the same DTC is output.
(e) Turn the power switch off.
B | GO TO STEP 4 |
|
4. | CHECK INVERTER COVER |
CAUTION:
Be sure to wear insulated gloves.
(a) Check that the service plug grip is not installed.
NOTICE:
After removing the service plug grip, do not turn the power switch on (READY), unless instructed by the repair manual because this may cause a malfunction.
(b) Check if the inverter cover of the inverter with converter assembly is installed correctly. OK: The inverter cover is installed correctly. | |
NG | INSTALL PARTS CORRECTLY |
|
5. | CHECK INVERTER COVER |
CAUTION:
Be sure to wear insulated gloves.
(a) Check that the service plug grip is not installed.
NOTICE:
After removing the service plug grip, do not turn the power switch on (READY), unless instructed by the repair manual because this may cause a malfunction.
(b) Remove the inverter cover from the inverter with converter assembly. Click here | |
