Wash away any remaining flux residue. Check for microscopic solder bridges between the pins using a loupe or digital microscope before attempting to reconnect the ECU to power.

: XC70 (2.4 D 185CV), XC90 (2.4D 163CV), and others utilizing EDC15 and EDC16 control units.

An external actuator (like a solenoid or injector) driven by the IC has shorted, pulling too much current through the B58944 driver circuit. nec b58944 datasheet hot

While exact specs can vary by manufacturer suffix, the general profile includes: PNP Silicon Transistor.

: Used in dashboard displays for models like the 911 (996). Wash away any remaining flux residue

Open the metal ECU casing carefully to avoid cracking the multi-layer PCB. Locate the SOP-28 chip marked with the NEC B58944 stamp.

The NEC B58944 datasheet provides a wealth of information on the component's specifications, characteristics, and applications. Here's a breakdown of what you can expect to find: An external actuator (like a solenoid or injector)

When a D43256BGU-70Y chip becomes "hot"—defined here as being significantly warmer than surrounding components or even scorching to the touch—it is typically a symptom of internal failure, not just high ambient operating temperature. Common Reasons for Overheating:
