To avoid personal injury or death fromelectrical shock, do not wear jewelry or damp clothing, and do not touch injector solenoids or solenoid wireswhen engine is operating.Table 4. Error Code 1314 - Injector Circuit Failure Troubleshooting Procedures.MALFUNCTIONTEST OR INSPECTIONCORRECTIVE ACTIONError Code 1312 - Injector Circuit Failure1. Place ignition switch to OFFposition and disconnectactuator harness from engineECU and from 15-pinconnector at front of enginebelow rocker arm cover.a. Inspect actuator harness,actuator harness connector,and 15-pin connector fordirty, corroded, bent,broken, pushed back, andextended pins.Clean and repair connector(s) asrequired (WP 0111 00).b. Check actuator harness,actuator harness connector,and 15-pin connector fordirt or moisture in or onconnector and for missingor damaged connectorseals.Remove dirt and moisture fromconnector. Replace missing ordamaged connector seals (WP0111 00).2. Place ignition switch to OFFposition and disconnectactuator harness and sensorharness from engine ECU andactuator harness from 15-pinconnector at front of enginebelow rocker arm cover.Perform the followingresistance checks.a. Measure resistance fromactuator harness connectorpin 2 to all other pins inactuator harness connector.Resistance should begreater than 100k ohms.a. If resistance is not asspecified, repair or replaceconnectors (WP 0111 00). b. If internal actuator harnessrequires replacement, notifySRA.
