Module, Onboard Charging (OBCM): Removal: Removal

WARNING: This page is about a different car, the 2014 Fiat 500e. However, it is still accessible from the selected car via links, so may be relevant.
WARNING:

On vehicles equipped with the high voltage system, you must thoroughly read and follow all High Voltage Safety procedures. In addition, before performing any diagnostic or service procedure near a high voltage component, you must perform the High Voltage Power Down. Failure to follow these instructions may result in possible serious or fatal injury. Refer to STANDARD PROCEDURE .

NOTE: When performing any key-on procedure you must charge the 12 volt battery with a setting of 20 amps minimum or the High Voltage Battery could discharge below recommended manufacture specifications and destroy the battery cells. 

WARNING:

When performing any repairs that involve contact with high voltage components or systems, the technician performing repairs on the vehicle must verify that the system remains powered down during high voltage repairs.

  • This must be done by removing the service disconnect.
  • The high voltage check out procedure must also be performed to ensure that the vehicle is properly powered down.
  • The technician must know the whereabouts of the service disconnect throughout the repair.
  • The technician must ensure that no one reconnects the service disconnect while service is being performed.
  • The technician must recheck that the service disconnect has not been reinstalled in cases where the vehicle was unattended.

Refer to ELECTRIC VEHICLE CONTROL SYSTEM, STANDARD PROCEDURE  to perform the High Voltage Power Down procedure.

  1. Disconnect the negative 12-volt battery cable.
  2. Power down the high-voltage system. Refer to ELECTRIC VEHICLE CONTROL SYSTEM, STANDARD PROCEDURE .
