B2103 — Ford PATS no transceiver communication
Universal diagnostic code. Below: what it means, common causes, symptoms, and the exact bench-programming fix path.
Common causes
- •PATS receiver ring failed (most common after 15-20 years)
- •Receiver wiring broken / damaged
- •Receiver disconnected during steering column work
- •PCM PATS input damaged from voltage surge
Symptoms you'll see
- •Crank-no-start
- •THEFT light steady or flashing
- •B2103 active with no other PATS codes
- •Same behavior with any key
The fix path
Most cost-effective fix: Ford PATS Delete ($199) bypasses the receiver entirely. Alternative: replace the PATS receiver ($200-400 dealer + 1-2 hours labor + 2-key reprogramming).
