B0455Display Module Internal Failure
- Generic OBD-II code · Body
- How the car detects it
- No J2012 list available to the public includes B0455, and factory literature is silent on it, so the code is unverified. It names an internal fault of a display module, such as the centre screen or a cluster panel, not its wiring or data link. Saab's 2011 9-5 sets B1020 when the radio gets an improper status reply from its display assembly, pointing to an electronics fault or a jammed button; on the 9-4X the same number covers the radio/HVAC control panel. Denso's US11348495B2 lets each display test its own circuit, report to the image ECU and, if it fails, hand speed and warnings to another screen. Hyundai Mobis (US11961434B2) spots a frozen picture through hidden test pixels. Bus loss to a display is U0162 or U0255; a dark screen with live content suggests B0490.
