EVC-324 < DTC/CIRCUIT DIAGNOSIS > P31D5 PRE-CHARGE RELAY P31D5 PRE-CHARGE RELAY DTC Logic INFOID:0000000010120792 DTC DETECTION LOGIC NOTE: If DTC P31D5 is displayed with DTC P0AA2, P31D4, P31DB, or P31DD, perform diagnosis for DTC P0AA2, P31D4, P31DB, or P31DD. DTC CONFIRMATION PROCEDURE 1. PRECONDITIONING • Turn power switch OFF and wait at least 90 seconds. CAUTION: During this period, never perform vehicle handling such as opening and closing of doors. If some kind of vehicle handling is performed, then wait another 90 seconds or more from the time of the vehicle handling. • Make sure that 12V battery voltage is 11 V or more. >> GO TO 2. 2. PERFORM DTC CONFIRMATION PROCEDURE With CONSULT 1. Set the vehicle to READY and perform test drive. 2. Turn power switch OFF and wait at least for 60 seconds. 3. Check self-diagnostic result. YES >> Proceed to EVC-324, "Diagnosis Procedure" NO >> INSPECTION END Diagnosis Procedure INFOID:0000000010120793 DANGER: Since hybrid vehicles and electric vehicles contain a high voltage battery, there is the risk of electric shock, electric leakage, or similar accidents if the high voltage component and vehicle are handled incorrectly. Be sure to follow the correct work procedures when performing inspection and maintenance. WARNING: • Be sure to remove the service plug in order to disconnect the high voltage circuits before perform- ing inspection or maintenance of high voltage system harnesses and parts. • To prevent the removed service plug from being connected by mistake during the procedure, always carry it in your pocket or put it in the tool box. • Be sure to wear insulating protective equipment consisting of glove, shoes, face shield and glasses before beginning work on the high voltage system. • Clearly identify the persons responsible for high voltage work and ensure that other persons do not touch the vehicle. When not working, cover high voltage parts with an insulating cover sheet or sim- ilar item to prevent other persons from contacting them. • Refer to EVC-10, "High Voltage Precautions" CAUTION: DTC CONSULT screen terms (Trouble diagnosis content) DTC detecting condition Possible cause P31D5 PRE CHARGE RELAY • The voltage of the traction motor inverter is 100 V or more im- mediately before starting charging or immediately before • The voltage of the traction motor inverter is 100 V or more when only the system main relay 2 is ON. • Harness or connectors |
