LI-ION BATTERY INSULATION RESISTANCE LOSS CHECK EVB-163 < DTC/CIRCUIT DIAGNOSIS > D E F G H I J K L M A B EVB N O P LI-ION BATTERY INSULATION RESISTANCE LOSS CHECK Component Inspection INFOID:0000000010121165 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. • The removed service plug must always be carried in a pocket of the responsible worker or placed in the tool box during the procedure to prevent the plug from being connected by mistake. • Be sure to wear insulating protective equipment consisting of glove, shoes, face shield and glasses before beginning work on the high voltage system. • Never allow workers other than the responsible person to touch the vehicle containing high voltage parts. To keep others from touching the high voltage parts, these parts must be covered with an insu- lating sheet except when using them. • Refer to EVB-7, "High Voltage Precautions" . CAUTION: Never bring the vehicle into the READY status with the service plug removed unless otherwise instructed in the Instruction. A malfunction may occur if this is not observed. The following diagnosis procedure must be performed when “P0AA6 or P33E1” are detected and Li-ion 1. CHECK MAXIMUM CELL VOLTAGE With CONSULT 1. Power switch ON. 2. Select “DATA MONITOR” of “HV BAT”. 3. Record “MAXIMUM CELL VOLTAGE”. NOTE: It is used, when replace a malfunction module. >> GO TO 2 2. CHECK INSULATION OF FRONT MODULE STACK LH-1 CAUTION: Check that high voltage harness and harness shield have no scratches and cracks. If any damage is found, replace damaged parts. 1. Remove Li-ion battery. Refer to EVB-181, "Removal and Installation" 2. Remove Li-ion battery controller. Refer to EVB-201, "LI-ION BATTERY CONTROLLER : Removal and . 3. Remove bus bar that connects front module stack LH and front module stack RH. between positive terminal of front module stack LH and battery pack ground. JSCIA0739ZZ |
