B119F-01 Quick Answer

B119F-01 on a 2011 F-150: Gps Antenna: General Electrical Failure. Ford’s factory diagnostic guidance for this code: GO to PINPOINT TEST N .

What Does B119F-01 Mean on a 2011 F-150?

The 2011 Ford F-150 uses the AUDIO CONTROL MODULE – WITH NAVIGATION to monitor and diagnose this circuit. B119F-01 is set when the module detects gps antenna: general electrical failure. The official meaning per the 2011 F-150 service information is exactly: GPS Antenna: General Electrical Failure.

Symptoms

  • Check engine light or system warning indicator on the instrument cluster
  • Reduced functionality of the affected audio control module – with navigation system
  • Possible co-codes from connected modules on the 2011 F-150 CAN bus (HS-CAN/MS-CAN)

Common Causes

  • Fault in the named component, sensor, or actuator circuit
  • Open or shorted wiring in the affected circuit
  • Connector corrosion or backed-out terminal
  • Loss of supply voltage or ground at the affected device
  • Module internal fault (rare — verify wiring and supplies first)

Ford-Recommended Diagnostic Action

Per the 2011 Ford F-150 service information for B119F-01:

GO to PINPOINT TEST N .

Pinpoint test references above are Ford F-150 service-manual chart numbers. Refer to the corresponding chart in the Ford 2011 F-150 Workshop Manual for step-by-step diagnostic procedures.

Diagnostic Approach

For B119F-01 on the 2011 Ford F-150 you’ll need a scan tool that reads the audio control module (nav variant) on the 2011 F-150, plus a digital multimeter and a working GPS antenna.

  1. Verify the code is current rather than just stored history. Use the scan tool’s self-test on the AUDIO CONTROL MODULE – WITH NAVIGATION.
  2. Read freeze-frame data and any related codes. Modules sharing CAN bus segments often log overlapping faults.
  3. Inspect the connector at the device named in the code description. Wiggle-test the connector while monitoring live data to expose intermittent faults.
  4. Measure supply voltage and ground integrity at the affected device with the engine running.
  5. Follow the Ford-recommended action above — including any pinpoint-test reference — for procedure-level diagnosis.
  6. If supplies are clean and the connector is sound, isolate the device with a known-good substitute. Re-clear the code and verify it does not return on a road test.

Possible Fixes

  • Replace the failed device or sensor identified during diagnosis
  • Repair open or shorted wiring
  • Connector pin-tension or pigtail repair
  • Module replacement and PMI (Programmable Module Installation) if the module itself is faulty

Can I Still Drive With B119F-01?

Drivability impact depends on the affected subsystem. AUDIO CONTROL MODULE – WITH NAVIGATION faults that affect a primary safety system (brakes, restraints, steering) should be repaired before further driving. Comfort or convenience faults can usually be deferred briefly without immediate safety risk.

FAQ

Will B119F-01 clear itself on a Ford F-150?

If the underlying fault was a momentary glitch — for example a brief connector dropout or a one-time low-voltage event — the B119F-01 may clear after a few drive cycles. Persistent root causes (failed device, broken wire, corroded terminal) will keep the fault active until the affected component is repaired on the Ford F-150.

Can I drive my Ford F-150 with B119F-01 active?

It depends which subsystem is affected. If the B119F-01 is in a primary safety system (brakes, restraints, steering, air suspension), the Ford F-150 should be driven only to a workshop. Comfort, lighting, and audio faults are lower priority but still worth addressing — the Ford F-150’s CAN architecture means a single unresolved code can mask others.

How much does it cost to fix B119F-01 on a Ford F-150?

Repair cost depends on the named device. On the Ford F-150, simple connector or wiring repairs typically run $80-200 in shop labour. Sensor replacements run $120-450 including parts and diagnostic time. Module replacement (when the affected control module itself has failed) is the most expensive path at $400-1,200 depending on whether the new module needs programming. Get a written estimate that breaks out diagnosis time, parts, and any required PMI / programming charge.

What does the official Ford F-150 service definition say about B119F-01?

Per the factory service information, B119F-01 is defined as: Gps Antenna: General Electrical Failure. The diagnostic procedure is in the Ford F-150 service-manual chapter for the affected module.
