In newer Peugeots, the dashboard and radio are intertwined. A common failure point is the unit. If the head unit develops a software glitch or internal hardware failure, it stops communicating on the CAN bus (the car's internal network), triggering the A9B7 code on the central computer.

As the automotive industry shifts towards electrification, autonomous driving, and connectivity, Peugeot (now part of the Stellantis group) is at the forefront of this change. Future Peugeot models are expected to incorporate these technologies, offering an exciting glimpse into what driving could look like in the years to come.

The output wiring harness leading away from the BSM can rub against sharp engine brackets or the transmission housing over time. If the insulation wears away and the ignition wire touches a live battery feed wire, it creates the exact short-to-positive scenario captured by code A9B7.

An "A9B7" code specifically indicates that the has detected a problem: a defect in the "+APC" relay from the ignition switch, or a short circuit to the positive supply (+12V) in the wiring harness that is coming out of that relay. In other words, a wire or a component in the +APC circuit is receiving constant power when it shouldn't be, or there is a direct, incorrect connection between two positive wires.

When the connection between the driver IC and the glass panel degrades, the screen loses its ability to render the pixel matrix, resulting in the "White Screen" phenomenon. In newer Peugeots, the dashboard and radio are intertwined

Test the pin matching the ignition positive (+APC) output harness.

The starter motor turns the engine over normally, but because the fuel injectors, ignition coils, or high-pressure fuel pumps lack main relay power, combustion never occurs. If the insulation wears away and the ignition

: Look for damaged or exposed wires in the output harness from the ignition relay that might be touching a power source, causing a short. Professional Diagnostic
