DTC Descriptor
DTC B0010 00
- Reverse Gear Signal Circuit
Circuit/System Description
The body control module (BCM) supplies B+ to the rearview camera when the transmission is placed into reverse.
Conditions for Running the DTC
Ignition voltage is between 9-16 volts
Conditions for Setting the DTC
The BCM detects there is a short to ground or an open circuit.
Action Taken When the DTC Sets
Rearview camera is disabled.
Conditions for Clearing
* The DTC will transition to history when the fault is no longer present.
* A history DTC will clear after 100 malfunction-free ignition cycles.

Circuit/System Testing
1. Ignition OFF, disconnect the harness connector at the rearview camera.
2. Ignition ON, park brake applied, transmission in REVERSE, test for B+ between the B+ circuit terminal 3 and ground.
瀚慖f less than the specified value, test the B+ circuit for a short to ground or an open/high resistance.
3. If all circuits test normal, replace the BCM.
