MALFUNCTION TEST OR INSPECTION CORRECTIVE ACTION Error Code 240 - Tophandler Leveling Locking Control, Wiring Circuit Failure - Continued b. If  voltage  is  not  present, enter     “Diag     ATTACH- MENT 15 (16)” menu and check    voltage    of    OSC. OUTPUT.  Voltage  should change from 0 to 24V and vice  versa  if  the  “leveling locked” switch is activated/ deactivated. a. If voltage is not as specified, replace ECU (791) (WP 0076 00). b. If voltage is changing, notify SRA. Table 4. Error Code 267 - Tophandler Leveling Right, Open Circuit Failure Troubleshooting Procedures. MALFUNCTION TEST OR INSPECTION CORRECTIVE ACTION Error  Code  267  -  Tophandler  Leveling  Right, 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 6035 from tophandler right leveling solenoid. Place ignition switch  to  ON  position  and perform voltage check at pins 1 and 2. If 20-25V is present at connector 6035,    replace    right    leveling 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 E and pin F.
