*1: The insulation malfunction detection circuit in the battery ECU assembly monitors the insulation resistance between the high voltage circuits and body. If the insulation resistance decreases, the hybrid vehicle control ECU assembly stores DTC P0AA649 and illuminates the master warning first regardless of malfunction area.
Depending on the vehicle condition, the high voltage circuit insulation resistance may return to normal. So if DTC P0AA649 is output, complete the following steps as soon as possible.
·*2: If the following operations are performed within the same trip after DTC P0AA649 is stored, just one of the related DTCs (P1C7C49, P1C7D49, P1C7E49, P1C7F49 or P1C8049) will be stored.

SYSTEM DESCRIPTION
- HINT:
-
If a decrease in insulation resistance cannot be confirmed using a megohmmeter, check "Short Wave Highest Value Level" in the Data List.
SHORT WAVE HIGHEST VALUE LEVEL
"Short Wave Highest Value Level" shows a decrease in insulation resistance. When insulation resistance decreases, "Insulation Lower" will be displayed. However, even though the insulation resistance of the vehicle is normal, "Short Wave Highest Value Level" may decrease, so that "Not Judge" will be displayed for any of the following conditions.
Within approximately 1 minute since the power switch was turned on (IG).
When the system voltages ("Hybrid/EV Battery Voltage", "VL-Voltage before Boosting", "VL-Voltage before Boosting for Rear Motor" and "VH-Voltage after Boosting") are changing.
During boosting. If the Data List item "Boost Ratio" is not 0% or within a few seconds of it becoming 0%. (The values of "Hybrid/EV Battery Voltage", "VL-Voltage before Boosting", "VL-Voltage before Boosting for Rear Motor" and "VH-Voltage after Boosting" are about the same when not boosting.)
When "No" is displayed for any of the following Data List items:
- Short Wave Highest Value Availability just after MG Inv On/Off
- Short Wave Highest Value Availability just after A/C Inv On/Off
- Short Wave Highest Value Availability just after SMR On/Off
- Short Wave Highest Value Availability just after Rear Motor Inv On/Off
When "Short Wave Highest Value Level" shows "Insulation Lower LV3", insulation resistance will be close to 0 Ω. In this case, damage to a high-voltage cable or hybrid component (high-voltage), or a short to body ground due to intrusion of foreign matter, such as metal particles, can be suspected.
RELATED FREEZE FRAME DATA
If problem symptoms cannot be reproduced and a malfunction still exists after replacing a part as instructed, checking the following freeze frame data can help determine a trouble area.
| Freeze Frame Data | Diagnostic Note |
|---|---|
| Short Wave Highest Value Level | Indicates that the insulation resistance has decreased. |
·
VL-Voltage before Boosting ·
VL-Voltage before Boosting for Rear Motor ·
VH-Voltage after Boosting ·
Hybrid/EV Battery Voltage ·
Boost Ratio |
During boosting (when "Boost Ratio" is not 0%), or when "VL-Voltage before Boosting", "VL-Voltage before Boosting for Rear Motor", "VH-Voltage after Boosting" or "Hybrid/EV Battery Voltage" is varying, "Short Wave Highest Value Level" may decrease even though the insulation resistance is normal. |
·
SMRP Status ·
SMRB Status ·
SMRG Status |
When "SMRP Status", "SMRB Status" and "SMRG Status" are all OFF, the insulation malfunction detection circuit detects a decrease in insulation resistance in the HV battery area ((*d) in the wiring diagram).
Example:
When the power switch is turned on (IG) (not on (READY)), all 3 system main relays are off and it is suspected that the HV battery assembly is disconnected from the high voltage circuits. If "Short Wave Highest Value Level" decreases a few minutes after the power switch is turned on (IG) (not on (READY)), the HV battery assembly may have an insulation malfunction. |
| Motor Inverter Shutdown Status | When "Motor Inverter Shutdown Status" is ON, the insulation malfunction detection circuit cannot detect a decrease in insulation resistance in the motor system AC (alternating current) section (motor (MG2) side of (*e) in the wiring diagram).
The motor system AC (alternating current) section includes the motor (MG2) in the hybrid vehicle transaxle assembly, motor cables and the AC (alternating current) section of the motor drive circuit in the inverter with converter assembly. |
| Generator Inverter Shutdown Status | When "Generator Inverter Shutdown Status" is ON, the insulation malfunction detection circuit cannot detect a decrease in insulation resistance in the generator system AC (alternating current) section (generator (MG1) side of (*e) in the wiring diagram).
The generator system AC (alternating current) section includes the generator (MG1) in the hybrid vehicle transaxle assembly, generator cables and the AC (alternating current) section of the generator drive circuit in the inverter with converter assembly. |
| Rear Motor Inverter Shutdown Status | When "Rear Motor Inverter Shutdown Status" is ON, the insulation malfunction detection circuit cannot detect a decrease in insulation resistance in the rear motor system AC (alternating current) section ((*g) in the wiring diagram).
The rear motor system AC (alternating current) section includes the rear motor (MGR) in the rear traction motor with transaxle assembly, rear traction motor cables and the AC (alternating current) section of the rear motor drive circuit in the inverter with converter assembly. |
| A/C Consumption Power | The compressor with motor assembly AC (alternating current) section ((*c) in the wiring diagram) includes the air conditioning motor, wiring between the air conditioning motor and air conditioning inverter, and the AC (alternating current) section of the air conditioning motor drive circuit in the air conditioning inverter.
With the vehicle stopped, turn on/off the air conditioning system and observe "Short Wave Highest Value Level" to use as a diagnosis reference. |

CAUTION / NOTICE / HINT
- CAUTION:
- ·
Refer to the precautions before inspecting high voltage circuit.
·
When troubleshooting DTC P0AA649, use either a tool wrapped with vinyl insulation tape or an insulated tool. (It is extremely dangerous when a high-voltage charge passes through a non-insulated tool causing a short.)
- NOTICE:
-
When using a megohmmeter set to 500 V to measure resistance, adhere to the following precautions.
- ·
Use a direct current(DC) resistance tester capable of measuring resistances of 100 MΩ or higher at DC 500 V when measuring resistance.
Do not use an alternating current(AC) resistance tester for this check as the correct measurement cannot be taken.
·After DC 500 V is applied and insulation resistance value has stabilized, read the measured value.
Time is needed for the insulation resistance value to stabilize. If a measurement value is read before it has stabilized, the correct measurement cannot be taken.
- HINT:
-
When measuring insulation resistance using a megohmmeter, set the megohmmeter to 500 V.
