Control Lamp Lights Up Intermittently (Will Not Go Out Unless Ignition Switch Is Cycled "OFF" & "ON")

If no fault can be detected with test adapter, the problem may be an interrupted wire or loose connection on one of the speed sensor cables or the ABS wiring harness.

Perform TEST 4, 5 and 6 with test adapter and multimeter (internal resistance of speed sensors). While testing, move cable at coaxial plug at cable connector and at speed sensor. If the ohmmeter indicates a break or loose connection, replace the speed sensor and coaxial cable or tighten connections at cable connector.
