TM 10-3930-675-20-1 0010 00-6 OVERLOAD PROTECTION TROUBLESHOOTING - CONTINUED 0010 00 Table 5. Error Code 134 - Right Lift Cylinder Pressure Sensor or Circuit Failure Troubleshooting Procedures. MALFUNCTION TEST OR INSPECTION CORRECTIVE ACTION Error Code 134 - Right Lift Cylinder Pressure Sensor or Circuit Failure 1.  Inspect    right    lift    cylinder sensors   and   connectors   for damage and secure mounting. Two  sensors  are  located  at locking  valve  at  base  of  lift cylinder. 2.  Remove cover from junction box X167, located at forward end  of  engine  compartment. Start engine and check voltage  between  pin  16  and pin 17. Voltage should be 20- 25V. If  voltage  is  present,  check voltage at junction box X167 pin 18. Voltage should be 0.3- 10.8V  depending  on  actual hydraulic pressure. If voltage is not present, replace right   cylinder   pressure   sensor (WP 0101 00). 3.  Remove   ECU   (790)   cover from operator’s seat base and slide ECU mounting tray out (WP 0079 00). 4.  Check ECU (790) connector 1, connector X159, and ECU tray    grounding    leads    for proper connection. a.  Connect any loose or disconnected connections. Push  ECU mounting  tray  in and install cover. b.  Repair or replace any damaged    connectors    (WP 0111 00). Push ECU mounting  tray  in  and  install cover. 5.  Perform    voltage    check    at connector X159 pin 3. Voltage should be 20-25V.
