TM 10-3930-675-20-1 0043 00-5 TOPHANDLER TILT TROUBLESHOOTING - CONTINUED 0043 00 Table 3. Error Code 237 - Tophandler Tilt Locking Control, Wiring Circuit Failure Troubleshooting Procedures - Continued. MALFUNCTION TEST OR INSPECTION CORRECTIVE ACTION Error   Code   237   -   Tophandler   Tilt   Locking Control, Wiring Circuit Failure b. If  voltage  is  not  present, enter   “DIAG   ATTACH- MENT 15 (16)” menu and check    voltage    of    TILT OUTPUT.  Voltage  should change from 0 to 24V and vice  versa  if  “tilt  locked” switch is activated/ deactivated. a. If voltage is not as specified, replace ECU (791) (WP 0076 00). b. If  voltage  is  not  changing, notify SRA. Table 4. Error Code 261 - Tophandler Tilt OUT Control, Wiring Circuit Failure Troubleshooting Procedures. MALFUNCTION TEST OR INSPECTION CORRECTIVE ACTION Error Code 261 - Tophandler Tilt OUT Control, Wiring 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 6010 from tophandler tilt OUT solenoid. Place  ignition  switch  to  ON position and perform voltage check. If 20-25V is present at connector 6010, replace tilt OUT solenoid (WP 0169 00). 3. Disconnect  connector  X188 from tophandler junction box on    boom.    Place    ignition switch  to  ON  position  and perform voltage check between connector X188 pin E and pin F. a.  If 20-25V is present, check continuity    between    con- nector   X188   pin   E   and connector    6010    pin    1; between   connector   X188 pin  F  and  connector  6010 pin 2; and between connector X188 pin F and ECU (791) connector 3 pin 4. a. If  continuity  is  not  present, repair  or  replace  connectors (WP 0111 00). b. If   wiring   harness   requires replacement, notify DS Maintenance.
