Pinpoint Test H: 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 battery
- IA key not present in the vehicle
- IA key not programmed
PINPOINT TEST H: 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.
-------------------------------------------------
H1 CHECK THE IA KEY LOCATION
- Place the IA key in several locations within the vehicle and attempt to start the vehicle
- Does the vehicle start with the IA in certain areas only?
Yes
GO to Pinpoint Test F. Pinpoint Test F: The Vehicle Does Not Start With The Intelligent Access (IA) Key In Certain Areas Within The Vehicle
No
GO to H2.
-------------------------------------------------
H2 RETRIEVE THE RFA MODULE DTCs
- Ignition OFF.
- Retrieve the RFA module continuous and on-demand DTCs.
- Are there any RFA module DTCs?
Yes
REFER to DTC Charts. Anti-Theft
No
GO to H3.
-------------------------------------------------
H3 CHECK THE IA KEY BATTERY
- Verify the correct battery is used (CR2032).
- Remove the IA key battery and measure the voltage.
- Is the voltage greater than 2.5 volts?
Yes
GO to H4.
No
INSTALL a new battery. DO NOT reprogram the IA key (damaged or dead batteries do not erase IA keys from memory). TEST the system for normal operation.
-------------------------------------------------
H4 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
CHECK the operation of the backup transceiver. GO to Pinpoint Test B. Pinpoint Test B: DTC B10D9:11, 12, 31 Or 87
No
PROGRAM the IA keys. REFER to Key Programming Using Diagnostic Equipment - Intelligent Access (IA) Using Diagnostic Equipment. TEST the system for normal operation.
