Jdm-040 Schematic

The refers to the motherboard found inside the DualShock 4 (DS4) Controller Model CUH-ZCT2 (the "Version 2" controller released around 2016). This model is distinct from the older JDM-001/011 models because it moved the light bar into the touchpad and introduced USB data communication via the Micro-USB port (allowing to play while charging), among other subtle changes.

The JDM-040 schematic reveals the analog stick circuit as two separate potentiometer arrays per stick (X and Y axes). Unlike the JDM-020, which used a rigid connector, the JDM-040 solders the analog stick module directly to the board. The schematic traces show that each stick uses a (VREF) split across a voltage divider. When the carbon wipers wear down, the returning voltage (VIN) gets stuck at a non-neutral value (either stuck high or low).

Technical discussions often center on specific failures within the JDM-040 circuit: Charging Circuit: Often fails due to a blown near the battery connector. Analog Drift:

This article provides a comprehensive breakdown of the JDM-040 board, its differences from previous revisions (JDM-001, JDM-020, JDM-030), and what you can expect to find when analyzing its schematic.

Since the buttons are "Active Lo," they activate when connected to Ground. Repairing these requires identifying the specific via for the button and ensuring it has a clean connection to the conductive film. The refers to the motherboard found inside the

The AcidMods community has identified specific spots on the JDM-040 for hardwiring modifications. Users can install tactile switches under the triggers and wire them directly to designated pads on the board. The pads for duplicating L1, R1, L2, and R2 are known, allowing for custom trigger stops or "hair trigger" adjustments.

To work efficiently with a JDM-040 schematic, always keep your multimeter set to continuity mode first to rule out VBUS-to-ground shorts. Treat the 3.2V and 1.8V rails as your foundational health indicators. If these rails are stable, any fault can generally be isolated to peripheral components like potentiometers, tactile switches, or the conductive ribbon film. Unlike the JDM-020, which used a rigid connector,

Furthermore, upcoming mod chips (like the ExtremeRate and VoiceMod modules) require soldering to precise test points on the JDM-040. Those test points (TP1, TP2 for UART debugging, etc.) are clearly marked on community-sourced schematics.

The JDM-040 is a motherboard revision found exclusively in the Sony CUH-ZCT2 series of wireless controllers, the second generation of the PlayStation 4's flagship controller. Released in 2016 alongside the PS4 Slim and PS4 Pro, the V2 controller offered subtle but significant upgrades over the original CUH-ZCT1.
