WIRING DIAGRAM









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 (DTC P0AFC-123 IS OUTPUT) P0A7F

B -- GO TO DTC P0AFC-123 P0AFC-123
A -- Continue to next step.

2. CHECK HARNESS AND CONNECTOR (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) Remove the battery smart unit Removal.

NOTICE:
Do not disconnect the battery smart unit connector.

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

(f) Connect the Techstream to the DLC3.

(g) Turn the ignition switch to ON and the Techstream on.

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

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

(j) Measure the voltage according to the value(s) in the table below while the battery cooling blower is operating.





Standard Voltage:
