Perform VERIFICATION TEST VER-1A.
  2. If voltage is not present, turn ignition off. Disconnect and inspect CAB 55-pin connector. Repair connector as necessary. With DRB-II in ohmmeter mode, probe terminal No. 4 (White/Light Green wire) of hydraulic unit connector. If resistance is less than 5 ohms, repair short to ground in White/Light Green wire.
  3. If resistance is more than 5 ohms, check resistance of White/Light Green wire between terminals No. 20 of CAB connector and No. 4 of hydraulic unit connector using an external ohmmeter. If resistance is more than 5 ohms, repair open in White/Light Green wire. Perform VERIFICATION TEST VER-1A.
  4. If resistance is less than 5 ohms, measure resistance of left front inlet valve. If resistance is 5-8 ohms, replace CAB. Perform VERIFICATION TEST VER-1A. If resistance is not 5-8 ohms, replace hydraulic control unit. Perform VERIFICATION TEST VER-1A.
