DTC SUMMARY
MALFUNCTION DESCRIPTION
The hybrid vehicle control ECU assembly monitors the high-voltage wiring between the HV battery and inverter with converter assembly and detects a power supply voltage malfunction to the inverter.
The cause of this malfunction may be one of the following:
Inside of inverter voltage sensor (VH) circuit malfunction
Voltage sensor (VH) malfunction
Motor generator control ECU (MG ECU) malfunction
Communication (wire harness) malfunction
High voltage system malfunction
HV battery malfunction
HV battery junction block assembly malfunction
Inverter with converter assembly malfunction
High-voltage wire harness malfunction
High-voltage connector or connection malfunction
Low-voltage circuit (12 V) malfunction
Hybrid vehicle control ECU assembly malfunction
HV battery junction block assembly malfunction
Low voltage wire harness malfunction
Low voltage connector malfunction
INSPECTION DESCRIPTION
| System Diagram Range | Inspection Content | Reason | Inspection Step |
|---|---|---|---|
| *a | Check connection condition and wire harness continuity between hybrid vehicle control ECU assembly and HV battery junction block assembly | In order to check whether connectors are connected properly and to check for an open circuit in the SMRP and SMRB primary lines | 3 to 6 |
| *b | Check system main relay | Check whether SMRB and SMRP stuck OFF | 7, 8 |
| *c | Check connection condition and high-voltage cable continuity between HV battery junction block assembly and inverter with converter assembly | Check for open circuit and defective connection (arc marks) due to looseness | 9 to 13 |
| *d | Check high-voltage cable and connection condition between HV battery and HV battery junction block assembly | Check for open circuit and defective connection (arc marks) due to looseness | 14 |
| *e | Check HV battery | Check whether HV battery voltage has drastically dropped below normal range | 15 |
DESCRIPTION
Refer to the description for DTC P0AE6-225.
| DTC No. | Detection Item | DTC Detection Condition | Trouble Area | MIL | Warning Indicate |
|---|---|---|---|---|---|
| P3004-132 | High Voltage Power Resource | Although an SMR on request was sent when the power switch is operated, the voltage did not increase after boosting. High-voltage circuit malfunctions between the HV battery and inverter with converter assembly. The EV electric battery fuse is blown, the service plug grip is removed, the system main resistor is blown, SMRP or SMRB remains open, or the high-voltage cable has an open circuit. (1 trip detection logic) |

WIRING DIAGRAM
Refer to the wiring diagram for DTC P0AA6-526.
Refer to the wiring diagram for the HV battery high-voltage line circuit.
CAUTION / NOTICE / HINT
CAUTION:
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 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.
Tech Tips
Waiting for at least 10 minutes is required to discharge the high-voltage capacitor inside the inverter with converter assembly.
When disposing of an HV battery, make sure to return it through an authorized collection agent who is capable of handling it safely. If the HV battery is returned via the manufacturer specified route, it will be returned properly and in a safe manner by an authorized collection agent.
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.
Tech Tips
After the repair, clear the DTCs and perform the following procedure to check that DTCs are not output.
Turn the power switch off and wait for 30 seconds or more.
Turn the power switch on (READY) and wait for 30 seconds or more.
PROCEDURE
CHECK DTC OUTPUT (HYBRID CONTROL)
Connect the GTS to the DLC3.
Turn the power switch on (IG).
Enter the following menus: Powertrain / Hybrid Control / Trouble Codes.
Check for DTCs.
