What is B0962?
Diagnostic Trouble Code (DTC) B0962 indicates a malfunction in the vehicle’s security system, particularly related to the keyless entry or immobilizer functions. This code is commonly found in various Ford models, especially the 2015-2020 Ford F-150 and Ford Escape. When this code appears, it typically means that the vehicle's Body Control Module (BCM) has detected an issue with the security system, preventing proper communication between the BCM and other modules. The implications of this malfunction can lead to issues such as the vehicle not starting or the alarm system activating unexpectedly. For car owners, understanding this code is essential as it directly affects the vehicle's security and functionality. If left unresolved, it could potentially lead to more significant problems, including locking you out of your vehicle or making it susceptible to theft. Addressing this code promptly can save time and money in the long run by avoiding further complications with your vehicle’s electronic systems.
