DIESEL CONTROL SYSTEM FLA -383 1) IG KEY "OFF", ENGINE "OFF". 2) Disconnect A/C pressure transducer connector and variable swirl control actuator connector. 3) IG KEY "ON". 4) Measure the voltage between A/C pressure transducer connector terminal 3 or variable swirl control actuator Specification : 4.8V~5.1V 5) Is the measured voltage within the specification? YES ▶ Go to "Component Inspection". NO ▶ Go to "2. Check short to ground in power circuit" as follows. 2. Check short to ground in power circuit 1) IG KEY "OFF", ENGINE "OFF". 2) Disconnect A/C pressure transducer connector, variable swirl control actuator connector, ECM connectors. 3) IG KEY "ON". 4) Measure the voltage between A/C pressure transducer connector terminal 3 or variable swirl control actuator specification : 0.0V~0.1V 5) Is abnormal voltate measured in this test? YES ▶ Repair short to battery and go to "Verification of Vehicle Repair". NO ▶ If the circuit is insulated well and the sensor power supply from ECM is high, replace ECM and go to "Verifi- COMPONENT INSPECTION EC8A090D 1. IG KEY "OFF", ENGINE "OFF". 2. Disconnect A/C pressure transducer connector and variable swirl control actuator connector. 3. Check that sensor connector power supply is within the specification after turning IG KEY "ON". 4. Connect A/C pressure transducer connector and variable swirl control actuator connector in turn. |
