EVC-184 < DTC/CIRCUIT DIAGNOSIS > P0AA6 HIGH VOLTAGE SYSTEM ISOLATION YES >> Replace electric compressor. Refer to HA-37, "Removal and Installation" (With heat pump sys- HA-95, "Removal and Installation" (Without heat pump system). NO >> Change refrigerant gas and compressor oil. 16. CHECK INSULATION RESISTANCE OF PDM (POWER DELIVERY MODULE) 1. Remove high voltage harness, normal charge port, and quick charge port from PDM (Power Delivery Module). Refer to VC-119, "Disassembly and Assembly" 2. Check insulation resistance of PDM (Power Delivery Module). Refer to CAUTION: • Since testers are polarized, check the polarity of the tester and connect it in the forward direc- tion to the circuit. • If the inspection results show no continuity, check the parts for proper installation. Is the inspection result normal? YES >> GO TO 17. NO >> Replace PDM (Power Delivery Module). Refer to VC-112, "Removal and Installation" 17. CHECK INSULATION RESISTANCE OF TRACTION MOTOR Check insulation resistance of traction motor. Refer to TMS-98, "Component Inspection" CAUTION: • Since testers are polarized, check the polarity of the tester and connect it in the forward direction to the circuit. • If the inspection results show no continuity, check the parts for proper installation. YES >> GO TO 18. NO >> Replace traction motor. Refer to TMS-109, "Removal and Installation" . 18. CHECK INSULATION RESISTANCE OF TRACTION MOTOR INVERTER Check insulation resistance of traction motor inverter. Refer to TMS-100, "Component Inspection" . CAUTION: • Since testers are polarized, check the polarity of the tester and connect it in the forward direction to the circuit. • If the inspection results show no continuity, check the parts for proper installation. YES >> Replace high voltage harness between PDM (Power Delivery Module) and Li-ion battery. NO >> Replace traction motor inverter. Refer to TMS-103, "Removal and Installation" . 19. CHECK INSULATION RESISTANCE OF PTC HEATER Check insulation resistance of PTC heater. Refer to HAC-181, "Component Inspection" [Auto A/C (with heat pump)] or HAC-341, "Component Inspection" [Auto A/C (without heat pump)]. CAUTION: • Since testers are polarized, check the polarity of the tester and connect it in the forward direction to the circuit. • If the inspection results show no continuity, check the parts for proper installation. YES >> GO TO 20. NO >> Replace PTC heater. Refer to HAC-201, "Removal and Installation" [Auto A/C (with heat pump)] or HAC-359, "Removal and Installation" [Auto A/C (without heat pump)]. 20. CHECK INSULATION RESISTANCE OF LI-ION BATTERY Check insulation resistance of Li-ion battery. Refer to EVB-163, "Component Inspection" . CAUTION: • Since testers are polarized, check the polarity of the tester and connect it in the forward direction to the circuit. • If the inspection results show no continuity, check the parts for proper installation. YES >> Check intermittent incident. Refer to GI-53, "Intermittent Incident" . NO >> Repair or replace error-detected parts. |
