Circuit/System Testing
1. Ignition OFF, disconnect the harness connector at the high voltage circuit impact detector sensor.
2. Ignition OFF and scan tool disconnected, open and close the driver door, and wait 1 minute. Test for less than 5 ohm between the low
reference circuit terminal 2 and ground.
锟斤拷 If greater than the specified range, test the low reference circuit for an open/high resistance. If the circuit tests normal, replace the serial
data gateway module.
Note: The serial data gateway module will attempt to communicate with the high voltage circuit impact detector sensor for 5 seconds
immediately after the ignition is turned ON. After 5 seconds the signal circuit will be inactive.
Note: The DMM should not be set on the Auto Range scale. The Auto Range will give erratic test results.
3. Connect a DMM, set on a manual setting that can read 12 V with the MIN/MAX function enabled, between the signal circuit terminal 1 and
ground.
4. Ignition ON, wait 10 seconds, The DMM reading should be less than 1.0 V.
锟斤拷 If greater than the specified range, test the circuit for a short to voltage. If the circuit tests normal, replace the serial data gateway module.
5. Verify the DMM MAX reading is greater than 6.0 V.
锟斤拷 If less than the specified range, test the circuit for a short to ground or an open/high resistance. If the circuit tests normal, replace the serial
data gateway module.
6. If all circuits test normal, test or replace the high voltage circuit impact detector sensor.

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.
