Circuit/System Testing

WARNING: This page is about a different car, the 2006 Chevrolet Monte Carlo and 2006 Chevrolet Impala. However, it is still accessible from the selected car via links, so may be relevant.
  1. Ignition OFF, disconnect the harness connector at the battery current sensor.
  2. Ignition ON, test for 5 volts between the battery current sensor supply voltage circuit, harness side and ground.
    • If the voltage is less than 5 volts, test the battery current sensor supply voltage circuit for a short to ground, a high resistance, an open circuit, or replace the BCM.
  3. Ignition ON, test for 5 volts between the battery current sensor supply voltage circuit and current sensor low reference circuit, harness side.
    • If the voltage is less than 5 volts, test the current sensor low reference circuit for a high resistance, an open circuit, or replace the BCM.
  4. Ignition ON, test for 5 volts between the battery current sensor signal circuit, harness side and ground.
    • If the voltage is less than 5 volts, test the battery current sensor signal circuit for a short to ground, a high resistance, an open circuit, or replace the BCM.
  5. If all 3 circuits test normal, replace the battery current sensor.
