Pinpoint Test A : No Key Detected Displays In The IPC (Instrument Panel Cluster) Message Center
WARNING: This page is about a different car, the 2018 Lincoln Navigator. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:
If unable to program new keys, follow the diagnostics for DTC B10C9:01.
- A1 CHECK FOR BCM (BODY CONTROL MODULE) ANTENNA DIAGNOSTIC TROUBLE CODES (DTCS)
- Ignition ON.
- Using a diagnostic scan tool, perform the BCM self-test. Record the Diagnostic Trouble Codes (DTCs).
Is BCM DTC B10C7:01 or B10C9:01 present?
Yes GO to A5 No GO to A2 - A2 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 A3 No REFER to:HANDLES, LOCKS, LATCHES AND ENTRY SYSTEMS . - A3 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 A4 - A4 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 A5 - Check for the use of consumer electronic devices that may cause interference with the passive key such as:
- A5 CHECK THE ANTENNA CIRCUITS FOR A SHORT TO VOLTAGE
- Ignition OFF.
- Disconnect: BCM C2280D .
- Ignition ON.
- Measure:
PATS Front Antenna
Positive Lead Measurement / Action Negative Lead C2280D-14 Ground C2280D-31 Ground Keyless Entry Rear Antenna
Positive Lead Measurement / Action Negative Lead C2280D-15 Ground C2280D-16 Ground
Is any voltage present?
Yes REPAIR the circuit in question. No GO to A6 - A6 CHECK THE ANTENNA CIRCUITS FOR A SHORT TO GROUND
- Ignition OFF.
- Measure:
PATS Front Antenna
Positive Lead Measurement / Action Negative Lead C2280D-14 Ground C2280D-31 Ground Keyless Entry Rear Antenna
Positive Lead Measurement / Action Negative Lead C2280D-15 Ground C2280D-16 Ground
Are the resistances greater than 10, 000 ohms?
Yes GO to A7 No REPAIR the circuit in question. - A7 CHECK THE ANTENNA CIRCUITS FOR AN OPEN
- Disconnect: PATS Front Antenna C347 .
- Disconnect: Keyless Entry Rear Antenna C4321 .
- Measure:
PATS Front Antenna
Positive Lead Measurement / Action Negative Lead C2280D-14 C347-2 C2280D-31 C347-1 Keyless Entry Rear Antenna
Positive Lead Measurement / Action Negative Lead C2280D-15 C4321-2 C2280D-16 C4321-1
Are the resistances less than 3 ohms?
Yes GO to A8 No REPAIR the circuit in question. - A8 CHECK THE RESISTANCE OF THE ANTENNANOTE: For a concern with key programming or if unable to start the vehicle with the passive key in the backup starting location, follow the diagnostics for the PATS front antenna.
- Connect: PATS Front Antenna C347 .
- Connect: Keyless Entry Rear Antenna C4321 .
- Measure:
PATS Front Antenna
Positive Lead Measurement / Action Negative Lead C2280D-14 C2280D-31 Keyless Entry Rear Antenna
Positive Lead Measurement / Action Negative Lead C2280D-15 C2280D-16
Is the resistance between 1 and 3 ohms?
Yes GO to A9 No INSTALL a new antenna for the one in question.* For the PATS front antenna, REFER to: Passive Anti-Theft System (PATS) Center Antenna .* For the PATS rear antenna, REFER to: Keyless Entry Rear Antenna . TEST the system for normal operation. If the concern is still present, GO to A9 - A9 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 service articles: TSB, GSB, SSM, or FSA. If a service article exists for this concern, DISCONTINUE this test and FOLLOW the service article instructions. If no service articles address this concern, BCM guided routine is not applicable for this vehicle and market. Replace the component that was faulted through service information diagnosis. 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.
