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.
Electronic Control Unit (Ecu)
ECU computes acceleration, deceleration and slip factors as generated from rotating wheels via 4 pulse sensors. ECU program can determine correct response behavior of the system based on these computations. ECU response is sent by electronic signals to electromagnetically operated valves in ABS hydraulic unit.
The ECU contains electronic monitoring circuits. These monitoring circuits ensure proper operation of ABS. If control unit detects a defect in wiring harness or any electrical equipment, monitoring circuit will switch off ABS, permitting normal use of standard brake system. ANTI-LOCK indicator light will glow.
