P3244 DRIVE MOTOR A INVERTER TMS-81 < DTC/CIRCUIT DIAGNOSIS > D E F G H I J K L M A B TMS N O P 1. Power switch ON and wait for 10 seconds or more. 2. Check DTC of the high voltage systems. YES >> Check DTC detected item. NO >> GO TO 2. 2. PRECONDITIONING WARNING: Disconnect the high voltage. Refer to GI-33, "How to Disconnect High Voltage" . Check voltage in high voltage circuit. (Check that condenser are discharged.) 1. Lift up the vehicle and remove the Li-ion battery under covers. Refer to 2. Disconnect high voltage harness connector and PTC heater harness connector from front side of Li-ion battery. Refer to EVB-181, "Removal and Installation" . 3. Measure voltage between high voltage harness connector terminals and PTC heater harness connector terminals. DANGER:
Touching high voltage components without using the appropriate protective equipment will cause electrocution. CAUTION: For voltage measurements, use a tester which can measure to 500 V or higher. >> GO TO 3. 3. CHECK TRACTION MOTOR INVERTER HIGH VOLTAGE BUS BAR Remove bus bar cover from PDM (Power Delivery Module) and check the tightness of high voltage bas bar. . Is the inspection result normal? YES >> GO TO 4. NO >> Tighten the high voltage bus bar to the specified torque. Refer to . 4. CHECK HIGH VOLTAGE HARNESS Check for an open circuit or short circuit between PDM (Power Delivery Module) and Li-ion battery. Refer to Is the inspection result normal? YES >> Replace the traction motor inverter. Refer to TMS-103, "Removal and Installation" . NO >> Repair or replace damaged parts. Standard : 5 V or less JPCIA0296ZZ |
