Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Manual Coding

- Vehicle Model
- ABS
- Manual Transmission
- 4-Speed Automatic Transmission
- With Cruise Control
- Without Cruise Control
- ETS
- Country Version
When returning a new control module, code number must be erased.
