Pinpoint Test A : No Key Detected Displays In The Message Center

WARNING: This page is about a different car, the 2018 Ford Edge. However, it is still accessible from the selected car via links, so may be relevant.

NOTE: Use the correct probe adapter(s) when making measurements. Failure to use the correct probe adapter(s) may damage the connector.

NOTE: If unable to program new keys, follow the diagnostics for DTC B10C8:01.

A1 CHECK FOR BCM (BODY CONTROL MODULE) ANTENNA DIAGNOSTIC TROUBLE CODES (DTCS)
- Ignition ON.
- Using a diagnostic scan tool, carry out the BCM self-test. Record the DTC.
- Ignition OFF.
Is DTC B10C7:01, B10C8:01, B11C6:01 or B11CA:01 present?

Yes GO to A8

No GO to A2

A2 CHECK IF THE PASSIVE KEYS START THE VEHICLE FROM THE BACKUP STARTING LOCATION
- Place the suspect passive key in the backup starting location and attempt to start the vehicle. REFER to: Passive Anti-Theft System (PATS) - System Operation and Component Description .
Does the key start the vehicle?

Yes GO to A5

No GO to A3

A3 DOCUMENT THE KEY IDENTIFICATIONS USING THE BCM (BODY CONTROL MODULE) KEY ID AND RTM (RADIO TRANSCEIVER MODULE) KEY ID PARAMETER IDENTIFICATIONS (PIDS)
- Using the diagnostic scan tool, view the BCM PIDs.
- Using the diagnostic scan tool, monitor the following BCM PIDs:
  - TIC_01_BCM (Programmed Transmitter ID Code (TIC) Value 1)
  - TIC_02_BCM (Programmed Transmitter ID Code (TIC) Value 2)
  - TIC_03_BCM (Programmed Transmitter ID Code (TIC) Value 3)

- Using the diagnostic scan tool, view the RTM PIDs.
- Using the diagnostic scan tool, monitor the RTM Lst_Xm_ID_Cd (Last Received Transmitter ID Code (TIC)) PID while pressing the lock and unlock buttons on the suspect key.
- Document the RTM Lst_Xm_ID_Cd TIC ID displayed when pressing the lock and unlock buttons on the suspect key.
- Compare the RTM TIC ID to the recorded BCM TIC IDs.
Does the RTM TIC ID match any of the recorded BCM TIC IDs?

Yes GO to A4

No No fault found. The key in question is not the original key that came with the vehicle.

A4 VERIFY THE KEY OPERATION

Check the operation of the suspect key.

Is the concern still present?

Yes	REPLACE the suspect key. PROGRAM the new key. Refer to the appropriate key programming procedure. REFER to: Anti-Theft Key Programming - Scan Tool .

No	The system is OK. The concern was caused by an incompleted programmed key.

A5 CHECK THE RKE (REMOTE KEYLESS ENTRY) TRANSMITTER OPERATION
- Press the lock and unlock RKE transmitter buttons on the suspect passive key.
Do the doors lock and unlock?

Yes GO to A6

No REFER to: Locks, Latches and Entry Systems .

A6 CHECK THE PASSIVE KEY LOCATION
- Check the location of the passive key. If it is placed in the far corners of the interior of the vehicle, move the passive key out of these areas and attempt to start the vehicle.
Does the vehicle start?

Yes The system is OK. INFORM the customer of the normal vehicle operation.

No GO to A7

A7 CHECK FOR ENVIRONMENTAL INTERFERENCE
- Check for the use of consumer electronic devices that may cause interference with the passive key such as:
  - other passive keys.
  - a charger that is plugged in.
  - a USB plugging into the media center.
  - a cell phone, speed pass or other electronic device next to the passive key.
- Remove any devices found and attempt to start the vehicle.
Does the vehicle start?

Yes INFORM the customer of the cause of the concern and the normal operation of the vehicle.

No GO to A8

A8 CHECK THE SUSPECT ANTENNA

NOTE: If no Diagnostic Trouble Codes (DTCs) are present, follow the diagnostics for the PATS center antenna.

A12 CHECK FOR CORRECT BCM (BODY CONTROL MODULE) OPERATION

Disconnect and inspect all of the BCM connectors.

Repair:
- corrosion (install new connectors or terminals, clean module pins)
- damaged or bent pins - install new terminals/pins
- pushed-out pins - install new pins as necessary

Reconnect all the BCM connectors and make sure they seat and latch correctly.

Operate the system and determine if the concern is still present.

Is the concern still present?

Yes	CHECK OASIS for any applicable TSB. If a TSB exists for this concern, DISCONTINUE this test and FOLLOW TSB instructions. If no TSB addresses this concern, refer to BCM Guided Routine Testing .

No	The system is operating correctly at this time. The concern may have been caused by module connections. Address the root cause of any connector or pin issues.
