OBDSTAR Expands BOSCH TC298 and TC299 Locked ECU Service with One-Time Boot Unlock and Bench Read/Write

OBDSTAR has extended its ECU service coverage to include more locked BOSCH TC298 and TC299 control units. The update gives technicians a more streamlined way to access ECU data and perform service work with less repeated disassembly.

Under the new workflow, a supported locked ECU can be Boot Unlocked once and then handled in Bench Mode for later read/write operations. This means the ECU housing does not need to be opened again for each subsequent data procedure.

What the New OBDSTAR Function Changes

Locked TC298 and TC299 ECUs normally require a boot unlocking step before internal data can be accessed. If the housing must be reopened repeatedly, workshops face extra labor time and a greater chance of physical damage to the module.

The OBDSTAR solution changes the process by allowing technicians to:

• Complete the BOOT Unlock procedure once
• Move to BENCH Read/Write mode for later operations
• Read and write ECU data without reopening the ECU housing
• Reduce turnaround time and improve workshop workflow

This function is particularly useful for workshops that regularly perform ECU cloning, calibration, tuning, repair, and data backup tasks.

OBDSTAR Devices That Support the Update

The following OBDSTAR tools currently support this function:

• OBDSTAR X300 Classic G3 (Key Master G3)
• OBDSTAR DC706
• ECU Master Full Version / A Configuration

With these devices, technicians can unlock supported ECUs and then carry out Bench Mode read/write operations.
