Pinpoint Test S: NO FOB DETECTED Is Displayed In The Message Center
Normal Operation
During each vehicle start sequence, if the Remote Function Actuator (RFA) module does not detect an Intelligent Access (IA) key is within the interior antennas range and the backup transceiver does not receive an IA key identification code, the message center in the Instrument Panel Cluster (IPC) displays the message NO FOB DETECTED.
NOTE: The IA key must be inside of the vehicle in order to be used for starting the vehicle. There are a few areas within the vehicle that are out of reach of the 3 interior vehicle antennas. If the IA key is located in one of these areas, a Passive Anti-Theft System (PATS) no-start may occur. Examples of these areas include:
- Open spaces within the upper areas of the vehicle interior, including the headliner area (between the visors and the headliner, and inside the overhead console)
- Far outside edges of the package tray
- Far outside edges of the top of the instrument panel, near the bottom of the windshield (interior side of the windshield)
- Far corners of the rear seat
If the IA key is located in one of these areas and there is a no-start condition (along with the NO FOB DETECTED message), move the IA key out of the area and attempt to start the vehicle.
This pinpoint test is intended to diagnose the following:
- IA key not present in the vehicle
- IA key not programmed
- RFA module
PINPOINT TEST S: NO FOB DETECTED IS DISPLAYED IN THE MESSAGE CENTER
NOTE: The ignition must be OFF to carry out the RFA module self-test. The ignition must be ON to carry out the network test for the RFA module.
NOTE: Some brands/types of mobile phone or laptop computer chargers can cause interference that can lead to a PATS no-start (along with the NO FOB DETECTED message) if the IA key is within a few inches of the charger. If a concern is observed, move the IA key away from the charger and attempt to start the vehicle.

S1 RETRIEVE THE RFA MODULE DTCs
- Ignition OFF.
- Connect the scan tool.
- Retrieve the RFA module continuous and on-demand DTCs.
- Are there any RFA module DTCs?
Yes
GO to DTC Charts. Anti-Theft - Intelligent Access (IA)
No
GO to S2.
-------------------------------------------------
S2 MONITOR THE RFA MODULE PID
- Enter the following diagnostic mode on the scan tool: Monitor the RFA Module DataLogger.
- Monitor the RFA module PID #Of_Prog_Xms (number of programmed keys).
- Does the RFA module PID #Of_Prog_Xms read 2?
Yes
GO to S4.
No
GO to S3.
-------------------------------------------------
S3 PROGRAM THE IA KEYS
- Program the IA keys. Refer to Key Programming Using Diagnostic Equipment - Intelligent Access (IA) Intelligent Access (IA).
- Enter the following diagnostic mode on the scan tool: RFA Module DataLogger.
- Monitor the RFA module PID #Of_Prog_Xms.
- Does the RFA module PID #Of_Prog_Xms read 2?
Yes
The system is operating correctly at this time. The concern may have been caused by an unprogrammed IA key.
No
Go To Pinpoint Test m. Pinpoint Test M: DTC B10D9:11, 12, 31 Or 87
-------------------------------------------------
S4 CHECK THE BACKUP TRANSCEIVER INTEGRITY
- Place the IA key in the backup transceiver slot.
- Attempt to start the vehicle, first with one IA key in the backup transceiver slot, then with the 2nd IA key in the backup transceiver slot.
- Does the vehicle start?
Yes
The IA key may be damaged or the IA key battery may have a low state of charge or may have failed.
INSTALL a new battery in the suspect IA key. CLEAR the DTCs. CYCLE the ignition. REPEAT the self-test. TEST the system for normal operation.
If the concern is still present after the battery replacement, REPLACE the suspect IA key and PROGRAM the new key. REFER to Key Programming Using Diagnostic Equipment - Intelligent Access (IA) Intelligent Access (IA).
No
GO to S5.
-------------------------------------------------
S5 CHECK FOR CORRECT RFA MODULE OPERATION
- Disconnect all the RFA module connectors.
- Check for:
- corrosion
- damaged pins
- pushed-out pins
- Connect all the RFA module connectors and make sure they seat correctly.
- Operate the system and verify the concern is still present.
- Is the concern still present?
Yes
INSTALL a new RFA module. RESET the parameters in both the RFA module and the PCM. REFER to Passive Anti-Theft System (PATS) Parameter Reset - Intelligent Access (IA) With Intelligent Access (IA). PROGRAM the IA keys into the new RFA module. REFER to Key Programming Using Diagnostic Equipment - Intelligent Access (IA) Intelligent Access (IA). CYCLE the ignition. REPEAT the self-test.
No
The system is operating correctly at this time. The concern may have been caused by a loose or corroded connector. CLEAR the DTCs. CYCLE the ignition. REPEAT the self-test.
