2012 Infiniti M35hFACTORY OEM SERVICE PROCEDURE
ABS FUNCTION: System Description: Notes
- By preventing wheel lock through brake force (brake fluid pressure) control that is electronically controlled by detecting wheel speed during braking, stability during emergency braking is improved so that obstacles can be easily bypassed by steering operation.
- During braking, control units calculates wheel speed and pseudo-vehicle speed, and transmits pressure increase, hold or decrease signals to actuator portion according to wheel slip status.
- The following effects are obtained by preventing wheel lock during braking.
- Vehicle tail slip is prevented during braking when driving straight.
- Understeer and oversteer tendencies are moderated during braking driving on a corner.
- Obstacles may be easily bypassed by steering operation during braking.
- CONSULT can be used to diagnose the system diagnosis.
- Fail-safe function is adopted. When a malfunction occurs in ABS function, the control is suspended for VDC function, TCS function, ABS function, brake limited slip differential (BLSD) function, brake assist function and Brake force distribution function. The vehicle status becomes the same as models without VDC function, TCS function, ABS function, brake limited slip differential (BLSD) function, brake assist function and Brake force distribution function. However, EBD function is operated normally. Refer to "FAIL-SAFE ".
