BEIJING TIME: 
CarLive is JCHCAR's field-proven online remote technical support protocol—proprietary source code built from years of domestic aftermarket practice. Sessions extend beyond the port with VIN-linked diagnostics, ECU programming, and China-network OTA for vehicles sourced through our B2B platform. The backend runs on a China-hosted KIMI3 AI Agent cluster (8× NVIDIA H100 GPUs) as an automotive software engineering copilot. Coverage follows official authorized brands and official self-operated store brands that already sell through stores in China—the brands inside JCHCAR’s cooperation.
CarLive · Beta
The same interface our partner dealers and JCHCAR buyers open after login—session chat, VCI setup, and OTA tasks in one workspace. Beta is enabled by your account manager against a real VIN.
Open CarLive Workbench
The same vehicle. The same account.
The VIN on the vehicle order is the basis for the next part: an airbag controller, a lamp, a condenser, or a harness. Vehicles bought through us, when the model supports it, can also use CarLive for remote diagnostics.

JCHCAR works with official self-operated stores, delivery centers, and brand-authorized dealers across Chaozhou, Shantou, and Jieyang—the Chaoshan cities—and in Guangzhou, Shenzhen, Dongguan, and Foshan. Remote diagnostics is a routine session.

CarLive reaches the anti-theft system through the OBD-II connector. The vehicle network and the multimedia network are not the same bus. The central gateway keeps them physically separate, so a diagnostic session does not travel on the cockpit’s internet path, and a fault on the head unit does not open the immobilizer.
01
The VCI plugs into the SAE J1962 diagnostic connector. The session addresses the immobilizer: PEPS, or the security module in the body domain, on CAN or CAN FD. That domain holds key learning, security access, and the controllers that must match the VIN. It is not a login on the center display.
02
The VCI is switched to Ethernet mode and joins the server JCHCAR subscribes to. A dedicated path continues into that brand’s official service station and dealer service station — the fiber addresses in Guangzhou, Shenzhen, and Shantou. The OEM tool meets a station address it already accepts.
03
The eSIM sits in the T-Box or the head unit. It is the internet uplink for the multimedia system. CarLive does not use it. After the vehicle arrives in the destination country, replace that eSIM so the entertainment system can reach the local internet. The diagnostic session does not depend on the swap.
An overseas workshop connects through a regional relay into JCHCAR subscription nodes in Guangzhou, Shenzhen, and Shantou. Those nodes use the fiber IP of each brand’s official service station and dealer service station, so diagnostics, programming, and OTA meet a China address the OEM already trusts.
Sharing options
CarLive is after-sales coverage for people who already import through JCHCAR. It is not a public workshop service and not a form you fill to become a dealer.

Most overseas China EV listings are brokered for a single transaction—typically $100–200 per unit—with no workshop network, no VIN lifecycle records, and no one accountable when OEM diagnostics, ECU programming, or OTA fail after the vehicle leaves China.

How CarLive works
An overseas workshop connects through a regional relay into JCHCAR subscription nodes in Guangzhou, Shenzhen, and Shantou. Those nodes use the fiber IP of each brand’s official service station and dealer service station, so diagnostics, programming, and OTA meet a China address the OEM already trusts.
Since 2021 we have supported authorized partners with China-network remote diagnostics—including international roaming, OBD2/VCI workflows, and coordinated OEM sessions. CarLive packages that capability into a secure dealer workbench backed by our KIMI3 AI Agent cluster, rolling out in beta to certified B2B partners worldwide.
Few China auto exporters offer post-delivery OEM access. CarLive is built for the gap our partner dealers and individual importers hit after the unit lands.
The session leaves your workshop, lands on the fiber IP of that brand’s official service station or dealer service station in Guangzhou, Shenzhen, or Shantou, and covers powertrain, ADAS, BCM, and EV/hybrid control units on JCHCAR-exported units.
When a local overseas network rejects a China-brand OTA package, the authorized update goes out through the Guangzhou, Shenzhen, or Shantou fiber node—with rollback coordinated where that brand’s channel allows.
Sessions respect OEM IP and authorization requirements—the same constraint that breaks ordinary VPN or offshore remote-desktop attempts for Chinese EV toolchains.
Every CarLive session ties to a JCHCAR order and VIN—complementing parts RFQs, warranty cases, and export records in one B2B account.

China-brand OTA servers often geofence or reject non-China IP ranges. Dealers abroad see failed downloads, blocked ECU writes, or silent update loops. CarLive sends the authorized package through subscription nodes in Guangzhou, Shenzhen, and Shantou, on the fiber IP of the brand’s official service station or dealer service station, and coordinates a rollback where that channel allows.

CarLive is JCHCAR's proprietary B2B remote support protocol for diagnostics and OEM-aligned OTA on vehicles purchased through our export platform. An overseas workshop reaches subscription nodes in Guangzhou, Shenzhen, and Shantou, on the fiber IP of each brand’s official service station or dealer service station.
JCHCAR is a professional China auto export B2B platform headquartered in Hong Kong with mainland operations—supplying LHD EVs and ICE vehicles to the Middle East, Africa, Europe, South America, and Southeast Asia. CarLive closes the after-sales gap that broker-only export cannot: VIN-level remote diagnostics and China-network OTA for dealers who need accountability after delivery.
CarLive is in beta and opening in phases for JCHCAR partner dealers and individual buyers on our export records. Capabilities depend on OEM authorization. We do not support vehicles sold outside JCHCAR, and we do not certify dealers from an open web form.
