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.
Anti-Lock Brake System (Abs) Module
| Refer to COMPONENT INDEX . |
The ABS module is an integral controller of the ACC with Stop and Go system. Most performance functions for this system route through or start from the ABS module.
The ABS module incorporates the EPB module, the ESC module and the Electronic Stability Protection (ESP) system and uses all of these modules and systems to help facilitate ACC with Stop and Go operation.
