Wiggle harness. Is resistance continuously less than 0.5 ohms? YES NO Reassemble coil and fuel tank. Measure voltage drop between battery (positive lead) and Terminal 87 (negative lead) on system relay with engine running. Is voltage drop less than 1.0 volt? Find source of intermittent and repair. YES NO Problem is fuel related. See symptoms under Table 5-3. Engine Performance Problems. Repeat voltage drop test after moving negative lead to Terminal 30. With engine running, is voltage drop less than 1.0 volt? YES NO Replace system relay. Repeat voltage drop test after moving negative lead to 15 amp ECM fuse (BE/GY wire). With engine running, is voltage drop less than 1.0 volt? YES NO Repair. BE/GY wire. Repeat voltage drop test after moving negative lead to 15 amp ECM fuse (R wire). With engine running, is voltage drop less than 1.0 volt? YES NO Replace 15 amp ECM fuse. STOP Go to Test 5.17 (Part 3 of 3). 5-62 2004 Touring: Engine Management (EFI)

HOME Test 5.17 (Part 3 of 3) MISFIRE AT IDLE OR UNDER LOAD Continued from Test 5.17 (Part 2 of 3). Repeat voltage drop test after moving negative lead to 40 amp maxi-fuse, terminal B. With engine running, is voltage drop less than 1.0 volt? YES NO Check terminal or repair wire. Repeat voltage drop test after moving negative lead to 40 amp maxi-fuse, terminal A. With engine running, is voltage drop less than 1.0 volt? YES NO Check terminal or replace maxi-fuse or terminals. Repair wire between maxi-fuse and battery. 2004 Touring: Engine Management (EFI) 5-63
