STEP 1. Check the signal line for short to power supply circuit (On board charger/DC-DC converter, main drive lithium-ion battery and PHEV-ECU).
(1) Disconnect the C-38 PHEV-ECU connector, D-34 main drive lithium-ion battery connector, D-208 on board charger/DC-DC converter connector, and measure at the wiring harness side.
(2) Measure the resistance between D-208 on board charger/DC-DC converter connector (terminal CHOT) and D-208 on board charger/DC-DC converter connector (terminal IGCT).OK: No continuity
Is the check result normal?
Go to Step 2. Repair the connector or wiring harness. Then go to Step 5.
