3. ASD OUTPUT CKT OPEN Turn the ignition off. Disconnect the EGR Solenoid harness connector. Turn the ignition on. Using a 12-volt test light connected to ground, check the ASD Relay Does the test light illuminate brightly? Yes >> Go To 4 No >> Repair the ASD Relay Output circuit for an open. Perform the ECM Verification Test Ver. 1 (Refer to 9 - 4. (K35) EGR SOLENOID CONTROL CIRCUIT SHORTED TO GROUND Turn the ignition off. Disconnect the EGR Solenoid harness connector. Disconnect the ECM harness connectors. Measure the resistance between ground and the (K35) EGR Solenoid Control circuit. Is the resistance above 1000 ohms? Yes >> Go To 5 No >> Repair the (K35) EGR Solenoid Control circuit for a short to ground. Perform the ECM Verification Test Ver. 1 (Refer to 9 - ENGINE - DIAGNOSIS AND TESTING). 5. (K35) EGR SOLENOID CONTROL CIRCUIT OPEN Measure the resistance of the (K35) EGR Solenoid Control circuit between the EGR Solenoid harness connector Is the resistance below 10.0 ohms? Yes >> Go To 6 No >> Repair the (K35) EGR Solenoid Control circuit for an open. Perform the ECM Verification Test Ver. 1 (Refer to 9 - ENGINE - DIAGNOSIS AND TESTING). 6. EGR SOLENOID Install a substitute EGR Solenoid in place of the vehicle’s EGR Solenoid. NOTE: Ensure the ECM and EGR Solenoid harness connectors are connected. With the scan tool, check for this DTC to set again. Did this DTC set again? Yes >> Replace and program the Engine Control Module in accordance with the Service Information. Perform the ECM Verification Test Ver. 1 (Refer to 9 - ENGINE - DIAGNOSIS AND TESTING). No >> Replace the EGR Solenoid. Perform the ECM Verification Test Ver. 1 (Refer to 9 - ENGINE - DIAGNOSIS AND TESTING). 9 - 950 ENGINE DIESEL DIAG KJ |
