Circuit/System Testing

WARNING: This page is about a different car, the 2011 Cadillac DTS. However, it is still accessible from the selected car via links, so may be relevant.

B1516 08

  1. Ignition OFF, disconnect the harness connector at the battery current sensor.
  2. Ignition OFF, and scan tool disconnected, open and close the driver door, and wait 1 minute. Test for less than 5 ohms between the low reference circuit terminal B and ground.
    • If greater than the specified range, test the low reference circuit for an open/high resistance. If the circuit tests normal, replace the BCM.
  3. Ignition ON, test for 4.8 - 5.2 volts between the supply voltage circuit terminal A and ground.
    • If less than the specified range , test the supply voltage circuit for a short to ground or an open/high resistance. If the circuit tests normal, replace the BCM.
    • If greater than the specified range , test the supply voltage circuit for a short to voltage. If the circuit tests, normal replace the BCM.
  4. Ignition ON, test for 4.8 - 5.2 volts between the signal circuit terminal C and ground.
    • If less than the specified range, test the signal circuit for a short to ground or an open/high resistance. If the circuit tests normal, replace the BCM.
    • If greater than the specified range, test the signal circuit for a short to voltage. If the circuit tests normal, replace the BCM.
  5. If all circuits test normal, test or replace the battery current sensor.

B1516 66 

When diagnosing B1516 66 verify that the battery current sensor is installed securely and positioned in the correct current flow direction.
