---|---|---|---|
P3245 | 203 | Malfunction (short circuit) in the generator inverter inside the inverter with converter assembly |
|
INSPECTION PROCEDURE
Note
DTC P3245-203 is stored after any of DTCs P0A7A-122, 130, 322, 324, 325, 517, 518, 809, 810, and 811 are stored. After troubleshooting and repairing DTC P3245-203, be sure to troubleshoot all the other DTCs.
The generator cable and hybrid vehicle transmission assembly may be affected depending on the vehicle operating conditions if a short occurs in the inverter with converter assembly. If DTC P3245-203 is output, inspect the generator cable and hybrid vehicle transmission assembly and replace the defective parts.
After completing the repair, test-drive the vehicle at a speed of approximately 40 km/h (25 mph) for 1 minute and check that DTC P0A92-261 (Hybrid Generator Performance) is not output. If DTC P0A92-261 (Hybrid Generator Performance) is output, replace the hybrid vehicle transmission assembly.
PROCEDURE
CHECK HYBRID VEHICLE TRANSMISSION ASSEMBLY (MG1)
CAUTION:
Be sure to wear insulated gloves.
Remove the service plug grip Click here.
Note
After removing the service plug grip, do not turn the power switch on (READY), unless instructed by the repair manual because this may cause a malfunction.
Disconnect the generator cable and motor cable from the inverter with converter assembly.

Check MG1 for an interphase short using a milliohmmeter.
Using a milliohmmeter, measure the resistance according to the value(s) in the table below.
Tech Tips
If the MG1 temperature is high, the resistance will vary greatly from the specification. Therefore, measure the resistance at least 8 hours after the vehicle is stopped.

Tech Tips
To correct the variation of the measured resistance due to temperature, use the following formula to calculate the resistance at 20°C (68° F).
R20 = Rt / {1 + 0.00393 X (T - 20)}
The calculation is based on the following:
R20: Resistance at 20°C (68° F) (mΩ)
Rt: Measured resistance (mΩ)
T: Temperature when the resistance is measured (° C)
Using a megohmmeter set to 500 V, measure the resistance according to the value(s) in the table below.
Note
Be sure to set the megohmmeter to 500 V when performing this test. Using a setting higher than 500 V can result in damage to the component being inspected.
