B1A75 Chrysler Code - Passive Entry Antenna 5 General Electric Failure
Quick Answer
The Passive Entry (PE) antenna units allow the transmitter within the Radio Frequency Hub (also known as the RF Hub) to communicate via Low Frequency (LF) radio transmission with a FOB with Integrated Key (FOBIK) that is located inside the vehicle or, at most, about 2 meters (6.5 feet) horizontally in all directions around the outside of the vehicle. Common causes include Faulty Passive Entry Antenna 5, Passive Entry Antenna 5 harness is open or shorted, Passive Entry Antenna 5 circuit poor electrical connection. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

Code B1A75 Chrysler Description
Each antenna unit has two dedicated connections to the RF Hub. One connection is the LF antenna output circuit, while the other connection Is the LF antenna return circuit. These circuits to each antenna unit are a twisted pair to help reduce the potential for induced electrical interference. The RF Hub microcontroller monitors all of the antenna units and will store a Diagnostic Trouble Code (DTC) for any fault that it detects.
The hard wired inputs and outputs of the antenna units may be diagnosed using conventional diagnostic tools and procedures. Refer to the appropriate wiring information. However, the most reliable, efficient, and accurate means to diagnose the antenna units requires the use of a diagnostic scan tool. Refer to the appropriate diagnostic information.
What are the Possible Causes of the DTC B1A75 Chrysler?
- Faulty Passive Entry Antenna 5
- Passive Entry Antenna 5 harness is open or shorted
- Passive Entry Antenna 5 circuit poor electrical connection
- Faulty Passive Entry Module (PEM)
- Faulty Radio Frequency Hub (RF Hub) Module
How to Fix the DTC B1A75 Chrysler?
Review the 'Possible Causes' above and visually examine the corresponding wiring harness and connectors. Check for damaged components and inspect connector pins for signs of being broken, bent, pushed out, or corroded.
