Symptom description
ESP OFF light illuminated
Equipment required
^ Tech2 with CANDi-box
^ 32MB Tech2 memory card (if possible, use a spare flashcard to avoid overwriting the ordinary Tech2-software).
^ Tech2 software version 1.000 (which is a Tech2 version only suitable for ESP reprogramming). Software available in Tis2Web can be downloaded to
the Tech2. It does not load automatically but requires the "custom mode". That will overwrite an existing content of the memory card.
^ External power supply to the car
Note
Ensure the memory card to Tech2 does NOT have the write protection activated.
1. Connect the external power supply to the car.
2. Connect Tech2 with software version 1.000 to the car and start Tech2.
3. Select "ESP reprogramming" from the menu and press Enter.
4. Read the information and press Enter.
5. If Tech2 can automatically identify the current software, it will display an information screen. If the information is correct, press OK.
6. If Tech2 can not identify the software, it displays a screen where you can manually select the software. Select the correct software and press OK.
7. Follow the instructions on the Tech2 screen.
8. Tech2 indicates when programming is finished.
