TM 10-3930-675-20-1 0007 00-15 ENGINE FUEL INJECTOR CIRCUITS TROUBLESHOOTING - CONTINUED 0007 00 WARNING Injector solenoids receive high voltage when engine is operating. To avoid personal injury or death from electrical shock, do not wear jewelry or damp clothing, and do not touch injector solenoids or solenoid wires when engine is operating. Table 4. Error Code 1314 - Injector Circuit Failure Troubleshooting Procedures - Continued. MALFUNCTION TEST OR INSPECTION CORRECTIVE ACTION Error  Code  1314  -  Injector  Circuit  Failure  - Continued 6. Measure resistance from injector solenoid pin A to pin B. Resistance should be 0.5- 1.5 ohms. a.  If  resistance  is  as  specified, replace   engine   ECU   (WP 0078 00). b. If     resistance     is     not     as specified, notify DS Maintenance to replace injector. 7. Place ignition switch in OFF position and, with rocker arm cover   removed,   disconnect internal actuator harness from injector solenoid and remove injector  solenoid  wires  from solenoid. 8. Measure resistance from post to post on solenoid. Resistance should be 0.5-1.5 ohms. If resistance is not as specified, notify DS Maintenance replace injector. Table 5. Error Code 1315 - Injector Circuit Failure Troubleshooting Procedures. MALFUNCTION TEST OR INSPECTION CORRECTIVE ACTION Error Code 1315 - Injector Circuit Failure 1. Place ignition switch to OFF position and disconnect actuator harness from engine ECU and from 15-pin connector  at  front  of  engine below rocker arm cover. a. Inspect   actuator   harness, actuator harness connector, and  15-pin  connector  for dirty, corroded, bent, broken,  pushed  back,  and extended pins. Clean and repair connector(s) as required (WP 0111 00).
