B173d Peugeot: Work
A weak CR2032 coin battery inside the remote control is the most frequent cause. While the passive transponder chip should theoretically work without power when placed directly against the emergency reader slot, a low battery prevents the key from broadcasting its long-range presence detection token, confusing the BSI. 2.

Troubleshooting the B173D Peugeot work code requires a systematic approach to identify the root cause of the problem. Here are the steps to follow:
To begin any diagnosis, one must understand the architecture of a Peugeot. The "B" in a potential B173D code indicates a system. This typically implicates the BSI (Boîtier Système Intelligent) , or Intelligent Systems Box. The BSI is the central computer managing everything from lighting and central locking to the instrument cluster and wipers. A code like B173D would likely point to a specific circuit within this network—perhaps a short to ground in the interior lighting circuit, a malfunction in a door lock actuator feedback line, or a communication breakdown on the VAN (Vehicle Area Network) or CAN (Controller Area Network) bus. b173d peugeot work
If diagnostics confirm the BSI is physically failing (corrosion or component burnout), it must be replaced.
For keyless systems, a simpler resynchronization method is to put the key in the emergency slot (often located in the steering column or armrest) for about 2 minutes before attempting to start. This allows the key and BSI to re-sync.
Before you begin any you must confirm the symptoms. A stored B173D code alone isn’t enough; you need to observe the vehicle’s behavior. A weak CR2032 coin battery inside the remote
The central computer (BSI) might have internal errors or corrupted software that needs a reset.
Every keyless Peugeot features an emergency transponder slot or a designated spot on the steering column where the key can be held. Placed here, the vehicle reads the chip using passive electromagnetic induction. If the car starts using this method, your issue lies strictly within the remote's battery or the vehicle's long-range antenna network. Step 2: Replace the Key Fob Battery

If your car is already running, the steering won't suddenly lock while driving. However, if you see this message, avoid driving long distances and get it to a workshop immediately. Once you turn the car off, the faulty lock might refuse to disengage again, leaving you stranded.
Locate the main earth points for the BSI, engine ECU, and ABS unit (usually on the chassis near the fuse boxes, or on the cylinder head). Ensure the terminals are clean, tight, and free from corrosion. A poor earth can cause the BSI to send corrupted signals, triggering B173D and other codes.
