Yes >> Go to 4 No >> Repair the (K365) Fuel Quantity Solenoid Control circuit for a short to the (K366) Fuel Quantity Solenoid 12 Volt Supply Perform the ECM Verification Test Ver. 1. (Refer to 9 - 4. (K365) FUEL QUANTITY SOLENOID CONTROL OPEN OR HIGH RESISTANCE Measure the resistance of the (K365) Fuel Quantity Solenoid Control Is the resistance below 10.0 ohms? Yes >> Go to 5 No >> Repair the (K365) Fuel Quantity Solenoid Control circuit for an open circuit or high resistance. Perform the ECM Verification Test Ver. 1. (Refer to 9 - 5. FUEL QUANTITY SOLENOID Connect the Engine Control Module (ECM) connector. Turn the ignition on. With the scan tool, actuate the Fuel Quantity Solenoid (CP3 Metering Pump) to 100%. Using a 12 volt test light connected to 12 volts, check the (K365) Fuel Quantity Solenoid Control circuit in the Fuel NOTE: The test light should be illuminated and bright. Compare the brightness to that of a direct connec- 9 - 1056 ENGINE ELECTRICAL DIAGNOSTICS - DIESEL LX |
