NOTE:
Check for any TSB(s) related to the condition. If a TSB applies, perform the procedure outlined in the TSB before continuing.
1. Turn the ignition on.
  NOTE:
  Make sure the battery voltage is between 10.0 and 16.0 volts.
2. With the scan tool, read the module status.
  NOTE:
  Check the BCM for any active CAN hardware DTCs, perform DTC before proceeding.
  
  Does the scan tool indicate that the module is active on the bus?
  
  Yes
  - The no response condition is not present at this time. Using the wiring diagram/schematic as a guide, inspect the wiring for chafed, pierced, pinched, and partially broken wires and the wiring harness connectors for broken, bent, pushed out, and corroded terminals.
  - Perform the BODY VERIFICATION TEST. Refer to STANDARD PROCEDURE .
  No
  - Go To Step 2

and on the initial network screen.
1. Turn the ignition off.
2. Disconnect the RF Hub Module C1 harness connector.
3. Using a 12-volt test light connected to ground, check the (A910) Fused B(+) circuit.
  Does the test light illuminate brightly?
  
  Yes
  - Go To Step 3
  No
  - Repair the open or short in the (A910) Fused B(+) circuit.
  - Perform the RADIO FREQUENCY HUB (RF HUB) VERIFICATION TEST. Refer to STANDARD PROCEDURE .

1. Using a 12-volt test light connected to 12 volts check the (Z911) Ground circuit.
  Does the test light illuminate brightly?
  
  Yes
  - Go To Step 4
  No
  - Repair the open in the (Z911) Ground circuit.
  - Perform the RADIO FREQUENCY HUB (RF HUB) VERIFICATION TEST. Refer to STANDARD PROCEDURE .
CHECK THE CAN C BUS VOLTAGE AT THE MODULE
1. Using a DVOM measure the voltage of the (D39) CAN C Bus (+) circuit at the RF Hub Module C1 harness connector and compare to Service Information. Refer to COMMUNICATION, OPERATION .
2. Using a DVOM measure the voltage of the (D40) CAN C Bus (-) circuit at the RF Hub Module C1 harness connector and compare to Service Information. Refer to COMMUNICATION, OPERATION .
  Do the voltages found indicate the CAN C Bus is active, when compared to Service Information?
  
  Yes
  - Replace the RF Hub Module in accordance with the Service Information. Refer to MODULE, RADIO FREQUENCY (RF HUB), REMOVAL .
  - Perform the RADIO FREQUENCY HUB (RF HUB) VERIFICATION TEST. Refer to STANDARD PROCEDURE .
  No
  - Repair the open in the (D39) CAN C Bus (+) or (D40) CAN C Bus (-) circuit. Inspect the connector for damage.
  - Perform the RADIO FREQUENCY HUB (RF HUB) VERIFICATION TEST. Refer to STANDARD PROCEDURE .
