The B1352 code on a Ford typically indicates an issue with the ignition key or the key transponder. This code is specific to Ford vehicles and is related to the PATS (Passive Anti-Theft System) system.

B1352 Code on a Ford

The PATS system is designed to prevent theft of the vehicle by disabling the engine starter motor and fuel pump if a key with an incorrect or unrecognized transponder is used to start the vehicle.

When the B1352 code is detected, it means that the PATS system has detected an error in the key transponder or in the ignition key itself. This can be caused by a number of factors, including a damaged or faulty transponder, a damaged or faulty key, or a malfunctioning PATS module.

In order to diagnose and repair the issue, it is recommended to take the vehicle to a qualified mechanic or dealership, as specialized tools and knowledge are required to properly diagnose and repair the PATS system.

The mechanic may use a code reader or scanner to read the B1352 code and identify the source of the problem and may need to replace the faulty key, transponder, or PATS module in order to resolve the issue.

Table: Possible causes of the B1352 code on a Ford and comments on each:

Possible CausesComments
Faulty KeyA damaged or faulty key can cause the PATS system to not recognize it, leading to the B1352 code. The key may need to be replaced or reprogrammed.
Faulty TransponderThe transponder in the key can also become damaged or faulty, preventing the PATS system from recognizing it. In this case, the transponder may need to be replaced or reprogrammed.
Malfunctioning PATS ModuleIf the PATS module itself is malfunctioning, it may not be able to properly recognize the key or transponder, leading to the B1352 code. In this case, the module may need to be replaced or reprogrammed.
Wiring IssuesWiring issues such as broken wires, short circuits, or poor connections in the PATS system can also cause the B1352 code. A thorough inspection of the wiring may be necessary to identify and repair any issues.
Failed PCMIn rare cases, a failed Powertrain Control Module (PCM) can cause the B1352 code. The PCM may need to be replaced or reprogrammed in order to resolve the issue.

It’s important to note that diagnosing and repairing the PATS system can be complex, and specialized tools and knowledge are required. It’s recommended to take the vehicle to a qualified mechanic or dealership for diagnosis and repair.

B1352 Code on a Ford symptoms

The B1352 code on a Ford can cause a variety of symptoms, including:

  1. Engine cranks but does not start: The PATS system is designed to prevent the engine from starting if an incorrect key or transponder is used, so if the B1352 code is present, the engine may crank but not start.
  2. Security light on: The security light on the dashboard may illuminate if there is an issue with the PATS system, indicating that the system is not recognizing the key or transponder.
  3. Loss of power: In some cases, the B1352 code may cause the engine to lose power or stall while driving. This can be dangerous, especially if it happens while driving at high speeds.
  4. No start at all: In some cases, the PATS system may completely prevent the engine from starting, even with the correct key or transponder. This can leave you stranded and in need of a tow to a repair facility.
  5. Key stuck in the ignition: If there is an issue with the PATS system, it may prevent the key from being removed from the ignition switch, even after the engine has been turned off.

If you experience any of these symptoms, it’s important to have your vehicle diagnosed and repaired as soon as possible to prevent further damage and ensure your safety while driving.

B1352 Code on a Ford Tech Note

The B1352 code on a Ford is related to the PATS system, which is designed to prevent theft of the vehicle by disabling the engine starter motor and fuel pump if an incorrect or unrecognized key or transponder is used to start the vehicle. The code indicates that there is an issue with the key or transponder, or with the PATS module itself.

When diagnosing the B1352 code, it’s important to first verify that the key being used is the correct key for the vehicle. If the key is damaged or worn, it may not be recognized by the PATS system, causing the code to be set. In some cases, it may be necessary to reprogram or replace the key.

If the key is found to be in good condition, the next step is to check the transponder in the key. The transponder emits a unique signal that is recognized by the PATS module, allowing the engine to start. If the transponder is damaged or faulty, it may need to be replaced or reprogrammed.

If the key and transponder are both in good condition, the next step is to check the wiring in the PATS system. Broken wires, short circuits, or poor connections can cause the B1352 code to be set. A thorough inspection of the wiring may be necessary to identify and repair any issues.

If the wiring is found to be in good condition, the last step is to check the PATS module itself. If the module is malfunctioning, it may not be able to properly recognize the key or transponder, causing the B1352 code to be set. In this case, the module may need to be replaced or reprogrammed.
