TM 10-3930-675-20-1 0007 00-3 ENGINE FUEL INJECTOR CIRCUITS TROUBLESHOOTING - CONTINUED 0007 00 Table 1. Error Code 1311 - Injector Circuit Failure Troubleshooting Procedures - Continued. MALFUNCTION TEST OR INSPECTION CORRECTIVE ACTION Error  Code  1311  -  Injector  Circuit  Failure  - Continued c. Measure   resistance   from actuator harness connector pin 10  to  all other pins  in actuator harness connector. Resistance should be greater than 100k ohms. a.  If     resistance     is     not     as specified,  repair  or  replace connectors (WP 0111 00). b. If   internal   actuator   harness requires  replacement,  notify SRA. d. Measure   resistance   from actuator harness connector pin 10  to  all other pins  in sensor  harness  connector. Resistance should be greater than 100k ohms. a.  If     resistance     is     not     as specified,  repair  or  replace connectors (WP 0111 00). b. If   internal   actuator   harness requires  replacement,  notify SRA. 3. Place ignition switch to OFF position and disconnect actuator harness from engine ECU.   Remove   rocker   arm cover (WP 0051 00). Disconnect  internal  actuator harness from 15-pin connector. a. Inspect    actuator    harness connector,    engine    ECU 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). b. Check     actuator     harness connector,    engine    ECU connector, and 15-pin connector for dirt or moisture in or on connector and for missing or damaged connector seals. Remove dirt and moisture from connector.  Replace  missing  or damaged  connector  seals  (WP 0111 00). 4. Place ignition switch in OFF position and disconnect internal actuator harness from 15-pin   connector   and   from no. 1 injector solenoid.
