Error Code 231 - Tophandler Spreader Opening, Open Circuit Failure Troubleshooting Procedures - Continued. MALFUNCTION TEST OR INSPECTION CORRECTIVE ACTION Error Code 231 - Tophandler Spreader Opening, Open Circuit Failure - Continued a.  If 20-25V is present, check continuity    between    con- nector   X188   pin   J   and connector    6018    pin    1; between   connector   X188 pin K and connector 6018 pin 2; and between connector X188 pin K and ECU (791) connector 2 pin 4. a. If  continuity  is  not  present, repair  or  replace  connectors (WP 0111 00). b. If   wiring   harness   requires replacement, notify DS Maintenance. b. If  voltage  is  not  present, enter   “DIAG   ATTACH- MENT  8  (16)”  menu  and check   current   of   20’-40’ OUTPUT.  Current  should be   present   with   joystick activated to open tophandler spreader. a. If   current    is    not    present, replace ECU (791) (WP 0076 00). b. If  current  is  present,  notify SRA. Table 2. Error Code 232 - Tophandler Spreader Opening, Short Circuit Failure Troubleshooting Procedures. MALFUNCTION TEST OR INSPECTION CORRECTIVE ACTION Error Code 232 - Tophandler Spreader Opening, Short 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 6018 from tophandler  spreader  opening solenoid. Place ignition switch to ON position. Error code  231  will  be  displayed. Perform voltage check at pins 1 and 2. If 20-25V is present at connector 6018, replace spreader opening solenoid (WP 0169 00).
