Abs Does Not Operate

Using ABS light diagnostics, ensure a normal Diagnostic Trouble Code (DTC) is output. See ABS LIGHT DIAGNOSTICS under DIAGNOSIS & TESTING. Check ignition power source circuit. See DTC 41 IGNITION POWER SOURCE CIRCUIT chart under DIAGNOSTIC CHARTS. Check speed sensor circuits. See DTC 31, 32, 33, 34, 35 & 36 SPEED SENSOR CIRCUIT charts under DIAGNOSTIC CHARTS. Check ABS actuator. See appropriate ACTUATOR CHECK under DIAGNOSIS & TESTING. If ABS actuator is okay, check hydraulic system for leaks. If above items are okay, replace ABS ECU.
