Pinpoint Test D : DTC B1D55:01: Notes

Diagnostic Overview 

Diagnostics in this article assume a certain skill level and knowledge of Ford-specific diagnostic practices. Refer to Diagnostic Methods in Service Information for information about these practices.

Normal Operation and Fault Conditions 

An external antenna connected to the Tire Pressure Monitor Module (TPM) receives a signal from the Intelligent Access (IA) key to enable activation of the remote start function from a distance of up to 100 meters (328 feet). If the external antenna fails, the remote start operates with a reduction in the range of operation.

Fault Trigger Conditions 

DTC Description Fault Trigger Conditions
B1D55:01 Antenna #2: General Electrical Failure Sets if the vehicle is equipped with remote start but the system feedback circuit does not detect an external antenna.
