: The car might start occasionally but fail at other times, often during specific weather conditions or after the vehicle has been sitting.
These models share similar door construction and mirror designs that are prone to wiring fatigue near the hinge point.
This code is categorized as a "Body" code, typically managed by the , which is the central control unit for the vehicle's electronic functions. When this fault is active, the vehicle's immobilizer system fails to recognize the authorized signal from the key fob, leading to several operational issues. Primary Symptoms : b173d peugeot
If you've connected a diagnostic tool to your Peugeot and seen , you are likely dealing with a frustrating "no-start" or "key not detected" scenario. This specific manufacturer code is a common headache for owners of modern models like the Peugeot 308, 3008, 5008, and the Partner van. What Does Fault Code B173D Mean?
The B173D error is rarely a mechanical failure. It is almost always an electrical or communication issue within the keyless system. : The car might start occasionally but fail
Open the hood. Locate the glow plug for Cylinder 4. Look for:
In the automotive world, fault codes are used to identify specific issues with a vehicle's systems. These codes are generated by the vehicle's onboard computer, known as the Engine Control Unit (ECU). When a problem arises, the ECU logs a code, which can then be retrieved using specialized diagnostic equipment. The B173D code seems to be related to a specific problem, but without further context, it's difficult to pinpoint the exact nature of the issue. When this fault is active, the vehicle's immobilizer
Turn on the side lights through the window to "wake up" the system, then try the ignition.
In simpler terms, the car's computer (ECU) has sent a signal to fold or unfold the mirrors, but the electrical circuit was not completed. The system detects a break in the "loop," meaning the electricity is not reaching the mirror motor or is not returning to the sensor.
: Software glitches or hardware faults within the BSI module can lead to intermittent key recognition failures.
: Low voltage in the main car battery can cause "ghost" faults in the BSI. Ensure the battery is fully charged (typically above 12.7V when off).
