Reading and Clearing Errors via ELS27 cable in FORScan

1. Preparation

Make sure the battery is charged or a stabilizer is connected (12.5–14 V).

Turn off all additional consumers: lights, radio, climate control.

Close the doors and the tailgate so that modules do not “wake up” during diagnostics.

Ignition ON, engine must not be started.

---

2. Connecting the ELS27

Connect the ELS27 to the vehicle’s OBD port.

Connect the USB cable to the laptop.

Launch FORScan.

In the adapter settings, make sure ELS27 is selected.

Menu: Options → Adapter Configuration → Select ELS27.

Click Connect.

Wait until the program detects all vehicle modules.

---

3. Reading Errors (DTC)

Go to: Diagnostics → Read DTC.

Select the module you want to check, or choose All Modules.

Click Read DTC.

FORScan will display a list of errors:

• Error code (for example, P0301)

• Description

• Status (active / stored / past events)

🔹 You can take a screenshot or export the report using the FORScan buttons to keep a history.

---

4. Clearing Errors

After reading the DTCs, make sure the issue has been resolved (otherwise the error will return).

Click Clear DTC.

Confirm the reset and wait for the completion message.

FORScan will remove all current active errors from the selected module.

🔹 After clearing errors, it is recommended to:

• turn the ignition OFF and then ON,

• perform adaptations/learning if required,

• drive 10–15 km so the system can refresh the data.

---

5. Additional Tips

If FORScan does not detect a module, check:

• Vehicle power supply (voltage 12–14 V)

• Adapter settings (make sure ELS27 is selected correctly)

• Cable and USB port

For stable ELS27 operation, use a direct USB cable without adapters or hubs.

Save backup DTC reports before clearing, especially when dealing with complex issues.

Activating Features via ELS27 in FORScan

Module Selection

Go to the menu:
Configuration and Programming → Module Configuration / Feature Programming.

Select the module in which you want to activate a feature
(for example, BCM for lighting features, IPC for instrument cluster menus).

FORScan will display a list of available parameters (options) for the module.

---

Feature Activation

Find the required feature in the list.

Change the value to Enabled / ON / 1 (depending on the parameter type).

If multiple features need to be activated, select all required ones.

Click Apply Changes or Program.

FORScan will first check compatibility and switch the module into programming mode.

---

Process Completion

Wait for the message: Programming completed successfully.

Cycle the ignition OFF → ON.

Check the operation of the new feature in the vehicle.

If necessary, restart the module or clear DTCs.

Step-by-Step Programming (Firmware Update) Process Using the ELS27 Adapter in FORScan

1. Preparation

Fully charge the battery or connect a stabilizer (13.2–14.0 V).

Turn off all additional devices: radio, lights, climate control, heaters.

Make sure all doors and the tailgate are closed.

Ignition ON, engine must not be started.

---

2. Connecting and Reading Modules

Connect the adapter to the OBD port and to the PC.

In Device Manager, make sure the port parameters are set correctly.

Launch FORScan and connect to the vehicle.

Wait until the program detects all modules.

Go to the menu: Programming and Configuration → Module Firmware Update.

Select the module you want to flash (for example, PCM, ABS, BCM, TCM).

---

3. Checking Available Firmware

FORScan will display the current Strategy, Calibration, and Boot versions.

The program will offer available newer versions.

Leave the suggested values if you are not sure — this is the safest option.

---

4. Backup

Click Download/Save current firmware.

Save the files for recovery in case of an error.

---

5. Pre-Programming Settings

Enable Stop bus activity.

If required, enable Program unchanged firmware (rewrite all files).

Enable Recovery mode only if the module is already “dead”.

---

6. Starting the Programming Process

Click Start.

FORScan will switch the module into programming mode.

The SBL (Secondary Boot Loader) will be loaded.

The program will write all firmware files.

Important:
Do not turn off the ignition, do not touch the cable, do not start the engine, and do not move the laptop.

---

7. Completion

Follow the FORScan prompts (sometimes ignition cycling is required).

Clear DTC errors.

Make sure communication with the module is restored.

If you see the message “Programming completed successfully”, the process has finished successfully.

---

8. Troubleshooting Common Issues

SBL does not load:
Check power supply and adapter, enable Stop bus activity, try another adapter.

Write / verification error:
Reconnect the adapter, re-download the firmware, enable Program unchanged firmware.

Module is “dead” after flashing:
Use Recovery mode and restore from the backup.

Low voltage:
Connect a stabilizer/charger and wait until voltage reaches 13+ V.

No firmware available:
Check internet connection, update FORScan; the module may not be supported.

New DTCs appear:
Perform adaptation procedures, clear errors, drive 10–15 km, and if necessary roll back to the backup.
