Battery Current Sensor Signal Invalid
- Ignition OFF, disconnect the harness connector at the battery current sensor.
- Ignition OFF, test for less than 1.0 ohm of resistance between the low reference circuit terminal B and ground.
- If the greater than the specified range, test the low reference circuit terminal B for an open/high resistance. If the circuit tests normal replace the BCM.
- Ignition ON, test for 5 volts between the battery current sensor supply voltage circuit terminal A and ground.
- If less than the specified range, test the battery current sensor supply voltage circuit terminal A for a short to ground or an open/high resistance. If the circuit test normal replace the BCM.
- Test for 5 volts between the battery current sensor signal circuit terminal C and ground.
- If less than 5 volts test the battery current sensor signal circuit terminal C for a short to ground or an open/high resistance. If the circuit test normal replace the BCM.
- If all circuits test normal test or replace the battery current sensor.

When to See a Mechanic
Stop DIY work and contact a certified mechanic immediately if any of the following apply:
- • You smell fuel, burning insulation, or see smoke.
- • Brakes feel soft, pull hard to one side, or make grinding noises.
- • The engine overheats, stalls repeatedly, or misfires under load.
- • You are missing required tools, torque specs, or safe lifting equipment.
- • You are not confident in the next step or safety outcome.
