WIRING DIAGRAM

Refer to the Wiring Diagram for DTC P0A84-123 P0A84.

INSPECTION PROCEDURE

CAUTION:
- Before inspecting the high-voltage system, take safety precautions to prevent electrical shocks, such as wearing insulated gloves and removing the service plug grip. 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 disconnecting the service plug grip, wait for at least 10 minutes before touching any of the high-voltage connectors or terminals.
HINT
At least 10 minutes is required to discharge the high-voltage capacitor inside the inverter with converter assembly.

PROCEDURE

1. CHECK DTC OUTPUT

(a) Connect the Techstream to the DLC3.

(b) Turn the ignition switch to ON.

(c) Enter the following menus: Powertrain / Hybrid Control / Trouble Codes.

(d) Read output DTCs Hybrid Battery System.

HINT
Check Cooling Fan Mode3 in the Data List. If the mode is 6, it is not necessary to perform the Active Test.

(d) Enter the following menus: All Data / VMF Fan Motor Voltage1 to 3.

(e) Check that the Data List value VMF Fan Motor Voltage3 is abnormal while operating the cooling fans (battery cooling blower assemblies). (*1)

(f) Disconnect the cable from the negative (-) battery terminal.

(g) Check that the service plug grip is not installed.

NOTICE:
After removing the service plug grip, do not turn the ignition switch ON (READY), unless instructed by the repair manual because this may cause a malfunction.

(h) Remove the battery cover and replace the battery cooling blower assembly (No. 2) with another battery cooling blower assembly Removal.





(i) Install the battery cover Installation.

(j) Connect the cable to the negative (-) battery terminal.

(k) Enter the following menus: Powertrain / Hybrid Control / Active Test / Driving the Battery Cooling Fan.

HINT
Check Cooling Fan Mode3 in the Data List. If the mode is 6, it is not necessary to perform the Active Test.

(l) Enter the following menus: All Data / VMF Fan Motor Voltage 1 to 3.

(m) Check if the blower assembly (from *1 above) malfunctions in a different location while operating the cooling fans (battery cooling blower assemblies) using the Active Test.

Result





B -- REPLACE BATTERY COOLING BLOWER ASSEMBLY (NO. 2) Removal
A -- Continue to next step.

3. CHECK HARNESS AND CONNECTOR (BATTERY SMART UNIT - BATTERY COOLING BLOWER ASSEMBLY [NO. 2])

CAUTION:
Be sure to wear insulated gloves and protective goggles.

(a) Disconnect the cable from the negative (-) battery terminal.

(b) Check that the service plug grip is not installed.

NOTICE:
After removing the service plug grip, do not turn the ignition switch ON (READY), unless instructed by the repair manual because this may cause a malfunction.

(c) Remove the battery cover Removal.

(d) Disconnect the O47 connector from the battery cooling blower assembly (No. 2).





(e) Disconnect the z18 connector from the battery smart unit.

(f) Measure the resistance according to the value(s) in the table below.





Standard Resistance:

5. READ VALUE USING TECHSTREAM (VM2 VOLTAGE)

CAUTION:
Be sure to wear insulated gloves and protective goggles.

(a) Disconnect the cable from the negative (-) battery terminal.

(b) Check that the service plug grip is not installed.

NOTICE:
After removing the service plug grip, do not turn the ignition switch ON (READY), unless instructed by the repair manual because this may cause a malfunction.

(c) Remove the battery cover Removal.

(d) Connect the cable to the negative (-) battery terminal.

(e) Connect the Techstream to the DLC3.

(f) Enter the following menus: Powertrain / Hybrid Control / Active Test / Driving the Battery Cooling Fan.

(g) Enter the following menus: All Data / VMF Fan Motor Voltage3.

(h) Select each air volume mode (1 to 6) in the "Driving the Battery Cooling Fan" active test to operate the battery cooling blower assembly.
