  1. Stop actuator test. Turn ignition off. Disconnect Controller Anti-Lock Brake (CAB) 60-pin connector. Inspect, clean and repair connector as necessary. Perform TEST VER-1A. If connector is okay, use scan tool in ohmmeter mode to check resistance of CAB connector terminal No. 48 (Dark Green/Light Blue wire). If resistance is less than 5 ohms, repair short to ground in Dark Green/Light Blue wire. Perform TEST VER-1A. If resistance is more than 5 ohms, go to next step.
  2. Reconnect Hydraulic Control Unit (HCU) 6-pin connector. Using scan tool, check resistance of CAB connector terminal No. 48 (Dark Green/Light Blue wire). If resistance is more than 5 ohms, repair open in Dark Green/Light Blue wire. Perform TEST VER-1A. If resistance is less than 5 ohms, go to TEST 20A.
