Ford Escape: High Voltage Battery, Mounting and Cables / General Procedures - Vent Patch

Repair

  WARNING: To prevent the risk of high-voltage shock, always follow precisely all warnings and service instructions, including instructions to depower the system. The high-voltage system utilizes approximately 450 volts DC, provided through high-voltage cables to its components and modules. The high-voltage cables and wiring are identified by orange harness tape or orange wire covering. All high-voltage components are marked with high-voltage warning labels with a high-voltage symbol. Failure to follow these instructions may result in serious personal injury or death.

NOTICE: If the vent patch is missing or damaged remove the high voltage battery cover and inspect inside the battery pack case for water/moisture before proceeding with repair. Refer to the high voltage battery cover removal procedure in this section.

NOTE: PHEV-A high voltage battery pack shown other high voltage battery packs similar.
