HYBRID / BATTERY CONTROL  HYBRID CONTROL SYSTEM  P19E100  DC/DC Converter System Performance  


DESCRIPTION

The DC/DC converter converts the voltage from the HV battery to supply power to the vehicle lights, audio system and various ECUs, etc.

At the same time, it performs charging of the auxiliary battery, controlling the output voltage to maintain a specific voltage at the auxiliary battery terminal.

Via CAN communication, the hybrid vehicle control ECU sends stop commands to the DC/DC converter, and receives DC/DC converter Normal/Malfunction status signals.

When an auxiliary charging system malfunction causes DC/DC converter output to stop, and either the auxiliary battery voltage is 11 V or more for 5 seconds or more, or the auxiliary battery voltage is 11 V or less for 0.05 seconds or more, this DTC is stored.

This DTC may also be stored if a malfunction of the inverter cooling system (blockage, inverter water pump malfunction, etc.) or a high-voltage insulation malfunction occurs.

·

After repair, clear the DTCs, turn the ignition switch off and wait for 30 seconds or more and perform the following procedure to confirm that the auxiliary battery low voltage indicated by this DTC has been repaired.

(a)

Wait for 2 minutes with the shift lever in P, the ignition switch ON (READY) and the following conditions met, then confirm that Data List item "BATT Voltage (Hybrid control system)" is between 13.0 and 15.0 V.

(If charging is not performed and the electrical load increases, +B voltage may not be steady and will gradually drop.)

(1)

Headlight switch is in the HI position.

(2)

A/C blower fan switch is in the HI position.

(3)

Window defogger switch is turned on.



·

By performing the following procedure, the DC/DC converter function can be checked.

(a)

Connect the AC/DC 400 A probe to the positive (+) auxiliary battery cable.

(1)

Turn the ignition switch to ON (READY) and leave the vehicle as is until the electric current flowing to the auxiliary battery becomes 10 A or less.

(2)

Turn the ignition switch to ON (READY) and turn the headlight switch and A/C blower fan switch to the HI position and the window defogger on.

(3)

Confirm that the current drawn from the auxiliary battery is 0 A or lower and the auxiliary battery voltage is between 13.0 and 15.0 V.




·

This DTC may be also stored when a part other than the DC/DC converter is malfunctioning or depending on user operation.


·

If this vehicle is used to jump start another vehicle with a discharged battery, a fuse may blow due to overcurrent or the DC/DC converter self-protection may be activated. Also, if this vehicle is jump started by a vehicle with a 24 V battery, the same malfunction may occur and this DTC may be stored. (The suspended DC/DC converter control will return to normal by clearing the DTCs and turning the ignition switch off.)


·

Check whether high electrical load equipment such as a high-capacitance audio device or electric kettle is used in the vehicle. (A fuse of the auxiliary battery may be blown due to overcurrent.)


·

If the DC/DC converter is malfunctioning, the auxiliary battery cannot be charged. Therefore, once the ignition switch is turned off, it may be impossible to turn it to ON (READY) again if the auxiliary battery is completely discharged. In this case, charge the auxiliary battery. Be careful as charging is not performed during the inspection.


·

If the ignition switch turns off immediately after it is turned to ON (READY), the auxiliary battery voltage may be low. Charge the auxiliary battery.


·

P19E100 may be output as a result of the malfunction indicated by the DTCs in table below.

(a)

The chart above is listed in inspection order of priority.

(b)

Check DTCs that are output at the same time by following the listed order. (The main cause of the malfunction can be determined without performing unnecessary inspections.)

P19E100 is output. A
P19E100 is not output. B


HINT:

As the DTC detection conditions include decreased auxiliary battery voltage, if the DTC is not input again, when the auxiliary battery is charged it can be judged that the vehicle has returned to normal.


b.

Turn the ignition switch off.

Using a megohmmeter set to 500 V, measure the insulation resistance according to the value(s) in the table below.

NOTICE:

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.


Standard Resistance:
Tester Connection Condition Specified Condition
Y2-1 (W) - Body ground and shield ground Ignition switch off 1 MΩ or higher
Y2-2 (U) - Body ground and shield ground Ignition switch off 1 MΩ or higher
Y2-3 (V) - Body ground and shield ground Ignition switch off 1 MΩ or higher
Y2-4 (W) - Body ground and shield ground Ignition switch off 1 MΩ or higher
Y2-5 (U) - Body ground and shield ground Ignition switch off 1 MΩ or higher
Y2-6 (V) - Body ground and shield ground Ignition switch off 1 MΩ or higher
