STEP 4. Voltage measurement at PHEV-ECU (terminal DCSW).
(1) Connect the C-41 PHEV-ECU connector, D-208 on board charger/DC-DC converter connector, and measure at the wiring harness side.
(2) Measure the PHEV-ECU connector side by backprobing.
(3) Depress the brake pedal, and turn on the power supply mode of the electric motor switch (READY operation).
(4) Measure the voltage between the PHEV-ECU connector (terminal DCSW) and body ground.OK: About 3 V lower than the system voltage.
Is the check result normal?
Go to Step 6. Go to Step 5.
