Tech Tips


  • *1: INF code 526 is stored together with P0AA6.

  • *2: The insulation malfunction detection circuit in the battery voltage sensor monitors the insulation resistance between the high voltage circuits and body. If the insulation resistance decreases, the power management control ECU stores DTC P0AA6-526 and illuminates the MIL first.

  • *3: If the following operations are performed within the same trip after DTC P0AA6-526 is stored, just one of the related DTCs (P0AA6-611, 612, 613 or 614) will be stored.


    1. Apply the parking brake firmly.

    2. Wait for 1 minute or more with the vehicle stopped, the brake pedal firmly depressed, the power switch on (READY), drive (D) selected and the air conditioning system on (Lo/COOL MAX, blower speed HI), then turn the power switch off and wait for 1 minute or more.

  • If DTC P0AA6 is stored, the vehicle cannot start.

  • When measuring insulation resistance using a megohmmeter, measure the resistance while jiggling the high voltage wire harness.

SYSTEM DESCRIPTION

Tech Tips

If a decrease in insulation resistance cannot be confirmed using a megohmmeter, check the Short Wave Highest Val in the Data List.


  1. Characteristics of Short Wave Highest Value


    1. The Data List item Short Wave Highest Val and insulation resistance have the relationship shown in the table below. Short Wave Highest Val decreases with a decrease in insulation resistance. However, in some cases, even though the insulation resistance of the vehicle is normal, Short Wave Highest Val may decrease. Therefore, check Short Wave Highest Val under the following conditions:


      • Approximately 1 minute has passed since the power switch was turned on (IG).*1

      • There is no difference between the system voltages (Power Resource VB, VL-Voltage before Boosting, and VH-Voltage after Boosting).*2

        Short Wave Highest Value Trouble Area
        Both conditions (*1 and *2) are met and Short Wave Highest Val is approximately 0 V Since the insulation resistance is close to 0 Ω, there is a strong possibility of interference with a metal object.
        Both conditions (*1 and *2) are met and Short Wave Highest Val is between 0 and 5 V Since the insulation resistance is several hundred kilo ohms, there is a strong possibility of the presence of fluid such as coolant.

  2. How to Determine Part with Insulation Malfunction


    1. Jiggle the high-voltage wire harness to check if the resistance to body ground changes with the position of the wire harness or force applied.

    2. Repeat rotating and stopping of the MG1, MG2 and compressor with motor assembly. Check that the Short Wave Highest Val does not decrease (for example if the motor stops with foreign matter forming a leak path) when the motor stops, or that the Short Wave Highest Val does not return to normal (for example if foreign matter moves away from the leak path) when the motor rotates.

    3. Increase the temperature of MG1and MG2. Check if the Short Wave Highest Val decreases with the temperature increase.

    4. Check that the transaxle fluid is not cloudy and the coolant level in the reserve tank has not dropped as the transaxle fluid will become cloudy when mixed with coolant, resulting in low insulation resistance.

INSPECTION PROCEDURE

CAUTION:


  • When performing P0AA6 troubleshooting, use either a tool wrapped with vinyl insulation tape or a insulated tool. (It is extremely dangerous when a high-voltage charge passes through a non-insulated tool causing a short.)

  • Before inspecting the high-voltage system or disconnecting the low voltage connector of the inverter with converter assembly or electric vehicle charger assembly, turn the power switch off. Also, 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 removing the service plug grip, wait for at least 10 minutes before touching any of the high-voltage connectors or terminals. After waiting for 10 minutes, check the voltage at the terminals in the inspection point in the inverter with converter assembly. The voltage should be 0 V before beginning work Click here.

    Tech Tips

    Waiting for at least 10 minutes is required to discharge the high-voltage capacitor inside the inverter with converter assembly and electric vehicle charger assembly.

  • When disposing of HV batteries and hybrid vehicle supply stack sub-assemblies, make sure to return them through an authorized collection agent who is capable of handling them safely. If they are returned via the manufacturer specified route, they will be returned properly and in a safe manner by an authorized collection agent.

  • Before returning the HV battery, make sure to perform recovery inspection Click here.

  • Before returning the hybrid vehicle supply stack sub-assembly, make sure to perform recovery inspection Click here.

  • Make a note of the output DTCs as some of them may be necessary for recovery inspection of the HV battery and hybrid vehicle supply stack sub-assemblies.

Note

After turning the power switch off, waiting time may be required before disconnecting the cable from the negative (-) auxiliary battery terminal. Therefore, make sure to read the disconnecting the cable from the negative (-) auxiliary battery terminal notices before proceeding with work Click here.

Tech Tips

When measuring insulation resistance using a megohmmeter, set the megohmmeter to 500 V.
