Circuit/System Verification

WARNING:

Always Perform the High Voltage Disabling procedure prior to servicing any High Voltage component or connection. Personal Protection Equipment (PPE) and proper procedures must be followed.

The High Voltage Disabling procedure includes the following steps:

Identify how to disable high voltage.
Identify how to test for the presence of high voltage.
Identify Condition under which high voltage is always present and personal protection equipment (PPE) and proper procedures must be followed.

Before working on any high voltage system, be sure to wear the following Personal Protection Equipment:

Safety glasses with appropriate side shields when within 15 meters (50 feet) of the vehicle, either indoors or outdoors.
Certified and up-to-date Class "0" Insulation gloves rated at 1000V with leather protectors.
- Visually and functionally inspect the gloves before use.
- Wear the Insulation gloves with leather protectors at all times when working with the high voltage battery assembly, whether the system is energized or not.

Failure to follow the procedures may result in serious injury or death.

Visually inspect the charge port for any obstruction or damage to the locking mechanism.
- If a mechanical issue is found
  Remove the obstruction if possible. Replace the component: X98 Battery Charger Coupler as necessary.
- Go to next step: If no mechanical issue can be found
Ignition - On/Vehicle - In Service Mode
Verify the scan tool parameter:
Battery Charger Coupler Lock display the same state.
- If not the specified state
  Refer to: DTC P3027-P3029
- Go to next step: If the specified state
Verify the scan tool parameter: Battery Charger Coupler Lock = The parameter value should not change
Perform the action while monitoring the parameter:
- Wiggle the harness and connector(s) : X2@X98 Battery Charger Coupler
- Wiggle the harness and connector(s) : X2@K16 Battery Energy Control Module
- If the parameter value changes
  Repair as necessary - Wiring/Terminal(s) /Electrical Connector(s)
- Go to next step: If the parameter value does not change
  Go to next step: Verify the physical Charge Port for lock and unlock actuation.
- If the lock does not actuate
  Refer to: DTC P0D91-P0D93 or P1C2F
  
  Refer to: Diagnostic Aids for manual lock release, if necessary.
- Go to next step: If the lock actuates and the parameter reports the correct state
All OK.
