Battery Disconnect And Connect - ETORQUE System

The graphic in this procedure depicts a typical negative battery cable and Intelligent Battery Sensor (IBS) connection at the negative battery post. The location of the battery and orientation of the cable eyelet connection to the IBS can vary between vehicles. Refer to the 12 VOLT BATTERY SYSTEM, DESCRIPTION AND OPERATION  for the 12 volt battery specific location.

DISCONNECT

1. Remove the ground terminal nut.
2. Remove and isolate the negative battery cable eyelet from the IBS. This will isolate the 12 volt and 48 volt battery from the vehicle electrical system.
   NOTE:

   If removing the negative battery cable clamp from the battery post instead of removing the negative battery cable eyelet, the Intelligent Battery Sensor (IBS) wire harness connector must be disconnecting prior to removing the cable end. Failure to disconnect the IBS wire harness connector can lead to damage of the IBS wire harness connector.

CONNECT

1. Install the negative battery cable eyelet to the IBS stud and secure using the nut. Tighten the nut to the proper torque specifications. Refer to TORQUE SPECIFICATIONS - BATTERY SYSTEM  .
   NOTE:

   Overtightening of the nut connecting the negative cable to the IBS will cause damage to the IBS or break the stud for the nut.

2. Connect the IBS wire harness connector if the negative battery cable clamp was removed.
