Diagnostic Test

1. Turn the ignition on.
2. Using the scan tool, record and erase the DTCs.
3. With the scan tool, select: RF Hub, More Options and System Tests.
4. Perform the RF Hub LF Antenna Verification Tests.
5. With the scan tool, read the Active DTCs.

   Does the scan tool display: B1A73-13-PASSIVE ENTRY ANTENNA 3 - CIRCUIT OPEN as active?

   Yes 

   • Go To  2

   No 

   • Test complete, the condition or conditions that originally set this DTC are not present at this time. Using the wiring diagrams as a guide, check all related splices and connectors for signs of water intrusion, corrosion, pushed out or bent terminals and correct pin tension.
   • Perform the BODY VERIFICATION TEST. Refer to BODY VERIFICATION TEST .

1. Turn the ignition off.
2. Disconnect the Radio frequency Hub (RF HUB) C2 harness connector.
3. Measure the resistance between the (D924) Passive Entry Antenna 3 Signal circuit and the (D925) Passive Entry Antenna 3 Return circuit.

   Is the resistance between 1.5 and 3.5 Ohms?

   Yes 

   • Replace the RF Hub in accordance with the Service Information. Refer to MODULE, RADIO FREQUENCY (RF HUB), REMOVAL .
   NOTE:

   If this vehicle is equipped with a Steering Column Lock Module (Export), it MUST be replaced also.

   • Replace the Steering Column Lock Module in accordance with the Service Information. Refer to MODULE, SHAFT LOCK, REMOVAL .
   • Perform the RADIO FREQUENCY HUB (RF HUB) VERIFICATION TEST. Refer to STANDARD PROCEDURE .

   No 

   • Go To  3
