P0A94-587 HBC-405 < COMPONENT DIAGNOSIS > D E F G H I J K L M A B HBC N O P • Before inspecting the high-voltage system or disconnecting the low voltage connector of the inverter with converter assembly, take safety precautions such as wearing insulated gloves and removing the service plug grip to prevent electrical shocks. After removing the service plug grip, put it in your pocket to prevent other technicians from accidentally reconnecting it while you are working on the high-voltage system. • After disconnecting the service plug grip, wait for at least 10 minutes before touching any of the high-voltage connectors or terminals. • Waiting for at least 10 minutes is required to discharge the high-voltage capacitor inside the inverter with converter assembly. >> GO TO 2. 2. CHECK DTC OUTPUT (HYBRID SYSTEM) 1. Turn ignition switch ON. 2. Check DTC. A, B, C or D A >> Go to inspection procedure relevant to output DTC (P0A1F-129). B >> Replace inverter with converter assembly (See HBC-638, "Removal and Installation" ). C >> Go to inspection procedure relevant to output DTC (P0A94-585). D >> GO TO 3. 3. CLEAR DTC 1. Turn ignition switch ON. 2. Read and record the DTCs and freeze frame data. 3. Clear the DTCs. >> GO TO 4. 4. CHECK DTC OUTPUT (HYBRID SYSTEM) 1. Turn ignition switch ON (READY) and move the shift lever to the N position. (*1) 2. Turn the A/C switch to the MAX COOL position. (*2) 3. Confirm that “PWR RESOURCE IB” is more than 3A in “DATA MONITOR” mode with CONSULT-III. (*3) 4. Leave the vehicle in the condition specified in steps (*2) and (*3) above for 15 seconds. (*4) NOTE: If the low battery charge warning light comes on, move the shift lever to the P position and start the engine to charge the HV battery. After the engine stops, perform steps (*1) through (*5) again. 5. Check DTC. (*5) A,B,C,D or E A >> Replace battery smart unit (See HBB-101, "Removal and Installation" B >> Replace inverter with converter assembly (See HBC-638, "Removal and Installation" ). C >> Leave vehicle in P position, and charge HV battery in idle status until idling stops (perform steps (*1) through (*5). D >> Replace battery smart unit (See HBB-101, "Removal and Installation" Output DTC Proceed to DTCs P0A94-587 and P0A1F-129 (HV battery voltage circuit malfunction) A DTCs P0A94-587 and P0A94-442 (Abnormal voltage execution value) B DTCs P0A94-587 and P0A94-585 (Boost converter voltage (VL) sensor performance problem) C DTC P0A94-587 only, or DTC P0A94-587 and DTCs other than above D DTC No. Relevant Diagnosis Proceed to P0A1F-129 HV battery voltage circuit malfunction A P0A94-585 Boost converter voltage (VL) sensor performance problem B P3000-388 Discharge inhibition C P3004-132 Power Cable Malfunction D No DTC is output. — E |
