Error Code 268 - Tophandler Leveling Right, Short Circuit Failure Troubleshooting Procedures - Continued. MALFUNCTION TEST OR INSPECTION CORRECTIVE ACTION Error  Code  268  -  Tophandler  Leveling  Right, Short Circuit Failure - Continued 3. Disconnect  connector  X189 from tophandler junction box at end of boom. Place ignition switch  to  OFF  position  and check    continuity    between connector 6035 pin 1 and pin 2    and    between    connector 6035  pin  1  and  pin  2  and chassis. a. If  continuity  is  not  present, repair  or  replace  connectors (WP 0111 00). b. If   wiring   harness   requires replacement, notify DS Maintenance. 4. Enter     “DIAG     ATTACH- MENT  14  (16)”  menu  and check current of OSCILLATION, RIGHT OUTPUT. Current should be present with joystick leveling right activated. a. If   current    is    not    present, replace ECU (791) (WP 0076 00). b. If  current  is  present,  notify SRA. Table 6. Error Code 270 - Tophandler Leveling Left, Open Circuit Failure Troubleshooting Procedures. MALFUNCTION TEST OR INSPECTION CORRECTIVE ACTION Error  Code  270  -  Tophandler  Leveling  Left, Open Circuit Failure 1. Check wires and cables from tophandler  control  valve  to boom for obvious damage. Repair    or    replace    damaged connectors (WP 0111 00). 2. Disconnect electrical connector 6036 from tophandler left leveling solenoid. Place ignition switch  to  ON  position  and perform voltage check at pins 1 and 2. If 20-25V is present at connector 6036,     replace     leveling     left solenoid (WP 0169 00). 3. Disconnect  connector  X189 from tophandler junction box at end of boom. Place ignition switch  to  ON  position  and perform voltage check between     connector     X189 pin G and pin H.
