A: Yes, the .40h suffix is specific to Smart diesel models. Gasoline Smart cars may have different interpretations or codes.
Do you experience this issue , or does it only happen intermittently (such as during rainy weather or after the car warms up)?
: If the pump fails the internal continuity bench tests, replace it with a brand-new OEM assembly or a certified premium aftermarket equivalent. Avoid buying low-cost used parts from salvage yards for this specific code; these pumps are highly susceptible to moisture degradation and typically fail shortly after installation.
A: Yes, it can leave you stranded. Addressing it promptly can prevent further damage to the transmission or TCU.
: Once the hardware fix is complete, use your OBD-II scanner to clear out the fault codes. Take the vehicle on an extended test drive that includes steady highway cruising to let the engine computer re-run its internal EVAP monitoring diagnostics and permanently clear the dashboard light.
If you are seeing this code on a "smart" scanner, the following issues are the most likely culprits: Faulty Leak Detection Pump:
Plug a professional-grade bi-directional scan tool (such as a Foxwell NT530 or specialized Mercedes XENTRY diagnostic device) into the OBD-II port. Isolate the freeze-frame records to see if the .40h fault is listed as or Stored/Intermittent . Step 2: Visual and Physical Pin Inspection
In everyday use the P2403.40H performs well for slides, spreadsheets, and video. Brightness and contrast make text readable even with some room lights on; colors are accurate enough for general multimedia and video playback. Its compact chassis simplifies mounting or moving between classrooms or meeting rooms. Fan noise stays low at typical brightness settings, preserving focus during presentations.
In most cases, the car will drive normally, as the fault is in the emission monitoring system rather than the engine's performance.
If you are running a small business, a startup, or a serious homelab and you are tired of the "jet engine" noise of enterprise gear, the Smart P2403.40H might be exactly what the doctor ordered. It bridges the gap between unmanaged "dumb" switches and loud, complex enterprise gear.
Replacing the physically worn internal clutch friction plates. $800 – $1,400
When this specific error code becomes active, your Smart car will display immediate, disruptive operational symptoms:
Smart vehicles do not use conventional torque-converter automatics or manual gearboxes. Instead, they rely on a built by Getrag. The system utilizes electronic actuators to engage the clutch and change gears mechanically.
