Pinpoint Test S: NO KEY 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 passive start 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 KEY DETECTED.
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 KEY 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.
-------------------------------------------------
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
REFER to DTC Charts. Anti-Theft - Intelligent Access (IA)
No
GO to S2.
-------------------------------------------------
S2 MONITOR THE RFA MODULE PIDs
- Enter the following diagnostic mode on the scan tool: RFA Module DataLogger.
- Monitor the RFA module PIDs N_KEYCODE (number of programmed keys) and MASTERKEY (PATS masterkey is present).
- Does the RFA module PIDs N_KEYCODE read 2 and MASTERKEY read Present?
Yes
GO to Pinpoint Test J. Pinpoint Test J: DTC B10C7:13, B10C8:13 Or B10C9:13
No
If the RFA module PID N_KEYCODE reads less than 2, GO to S3.
If the RFA module PID N_KEYCODE reads 2, but MASTERKEY reads No, GO to S3.
-------------------------------------------------
S3 PROGRAM THE IA KEYS
- Program the IA keys. Refer to Key Programming Using Diagnostic Equipment - Intelligent Access (IA) With Intelligent Access (IA).
- Enter the following diagnostic mode on the scan tool: RFA Module DataLogger.
- Monitor the RFA module PIDs N_KEYCODE and MASTERKEY.
- Does the RFA module PIDs N_KEYCODE read 2 and MASTERKEY read Present?
Yes
The system is operating correctly at this time. The concern may have been caused by an unprogrammed IA key.
No
GO to S4.
-------------------------------------------------
S4 CHECK THE BACKUP TRANSCEIVER INTEGRITY
- Place the IA key in the backup transceiver slot.
- Enter the following diagnostic mode on the scan tool: Monitor the RFA Module PIDs.
- Monitor the RFA module PIDs N_KEYCODE and MASTERKEY.
- Does the RFA module PIDs N_KEYCODE read 2 and MASTERKEY read Present?
Yes
The IA key battery may have a low state of charge or may have failed. INSTALL a new battery in the IA key. CLEAR the DTCs. CYCLE the ignition. REPEAT the self-test.
No
GO to Pinpoint Test M. Pinpoint Test M: DTC B10D9:11, 12, 31 Or 87
