2. (K38) FUEL INJECTOR NO. 5 HIGH-SIDE CONTROL CIRCUIT SHORTED TO VOLTAGE Turn the ignition off. Disconnect the Fuel Injector No. 5 connector. Disconnect the Engine Control Module (ECM) connector. Remove the ASD Relay from the IPM. Connect a jumper wire between cavity 30 and cavity 87 of the ASD Turn the ignition on. Measure the voltage of the (K38) Fuel Injector No. 5 High-Side Control Is there any voltage present? Yes >> Repair the (K38) Fuel Injector No. 5 High-Side Control cir- cuit for a short to voltage. Perform the ECM Verification Test Ver. 1. (Refer to 9 - ENGINE - DIAGNOSIS AND TESTING) No >> Go to 3 3. (K638) FUEL INJECTOR NO. 5 LOW-SIDE CONTROL CIRCUIT SHORTED TO VOLTAGE NOTE: The jumper wire should still be in place. Is there any voltage present? Yes >> Repair the (K638) Fuel Injector No. 5 Low-Side Control cir- cuit for a short to voltage. Perform the ECM Verification Test Ver. 1. (Refer to 9 - No >> Go to 4 4. (K38) FUEL INJECTOR NO. 5 HIGH-SIDE CONTROL CIRCUIT SHORTED TO GROUND Turn the ignition off. Measure the resistance between ground and the (K38) Fuel Injector No. Is the resistance above 1000.0 ohms? Yes >> Go to 5 No >> Repair the (K38) Fuel Injector No. 5 High-Side Control cir- cuit for a short to ground. Perform the ECM Verification Test Ver. 1.
