SLABS ECU




SLABS ECU







The SLABS ECU provides the road speed signal to the cruise control ECU. This is the same speed signal provided to the ECM. Cruise control will only operate between 28 - 125 mph (45 - 200 km/h). Cruise control will not operate if a road speed signal is not present.

Input/Output







The input from the SLABS ECU to the cruise control ECU is a square wave oscillating between 0 - 12 Volts at a frequency of 8,000 pulses per mile (1.6 km).
