iCarsoft JP V4.0
The iCarsoft JP V4.0 delivers comprehensive diagnostics across every onboard ECU—including the engine, transmission, ABS, and SRS/Airbag. Designed for serious DIYers and independent repair shops, the JP V4.0 goes far beyond basic code reading — delivering OE-level ECU coding, advanced adaptations, and full bidirectional control.
One specialist tablet for the cars of the East — read, code, and command, all without a PC.
The JP V4.0 is the touchscreen evolution of iCarsoft’s Asian-vehicle specialist line. Where the older JP V3.0 needed buttons and a USB cable, this generation puts a 5-inch Android workstation in your hand — pairing full-system coverage with bidirectional control, dealer-level coding and over-the-air updates. Sixteen Asian makes, one purpose-built tool for the bench or the driveway.
Tuned for Japanese & Korean iron — sixteen makes, zero compromise.
Purpose-built coverage for the Asian brands you actually work on — for Daewoo, for Acura, for Honda, for Hyundai, for KIA, for Isuzu, for Mazda, for Mitsubishi, for Infiniti, for Nissan, for Nissan GTR, for Subaru, for Suzuki, for Lexus, for Scion, for Toyota.

Good to know before you buy.
Yes! The iCarsoft JP V4.0 includes lifetime free software upgrades via Wi-Fi. There are zero annual subscription fees or hidden costs. You pay once and get continuous software updates forever.
Not at all. AutoVIN depends on individual vehicle ECU protocols. If AutoVIN skips your car, simply use the Manual Selection mode—all diagnostic and service functions will work perfectly. Meanwhile, please send your VIN to our support team; we will verify it and add it to our database in the next software update.
Please keep ignition on and engine off. Record freeze frame data first before clearing codes.
- Persistent hardware faults need physical repair prior to code clearance.
- Some fault codes of systems like SRS and ABS can only be cleared after finishing bidirectional tests.
Please check the following steps to troubleshoot:
Check Vehicle Compatibility: Ensure your vehicle is covered by the JP V4.0, please kindly refer to the vehicle coverage of JP V4.0.
Turn Off Power-Saving: Disable any eco/battery-saving modes on the vehicle that might shut down modules during diagnosis.
Update Device: Connect to Wi-Fi and update both the firmware and vehicle software to the latest versions.
Check Ignition: Ensure the vehicle key is turned to the “ON” position.
The JP V4.0 is the upgraded successor to the JP V3.0. It transforms the traditional button-operated scanner into a smart 5″ Android touchscreen device, adding convenient one-click Wi-Fi updates and advanced ECU coding—all without needing a PC.
