Circuit/System Testing

WARNING: This page is about a different car, the 2007 Pontiac G5 Pursuit, 2007 Pontiac G5, and 2007 Chevrolet Cobalt. However, it is still accessible from the selected car via links, so may be relevant.
  1. Ignition ON and the battery current sensor harness disconnected, with a DMM measure the voltage of the current sensor supply voltage, harness side and ground. The voltage should read 5.0 volts.
    • If the voltage is less than 5.0 volts test the current sensor supply voltage for a short to ground, a high resistance, an open circuit.
    • If the circuit tests good replace the BCM.
  2. Ignition ON and the battery current sensor harness disconnected, with a DMM measure the voltage of the current sensor signal circuit, harness side and ground. The voltage should read 5.0 volts.
    • If the voltage is less than 5.0 volts test the current sensor signal circuit for a short to ground, a high resistance, an open circuit.
    • If the circuit tests good replace the BCM.
  3. Ignition ON and the battery current sensor harness disconnected, with a DMM measure the voltage of the current sensor supply voltage and current sensor low reference circuit, harness side. The voltage should read 5.0 volts.
    • If the voltage is less than 5.0 volts test the current sensor low reference circuit for a high resistance, an open circuit.
    • If the circuit tests good replace the BCM.
  4. If all 3 circuits test good replace the battery current sensor.
