Dakota Trucks 1989-1996 Ignition Tests COIL The ignition coil for the vehicles covered by this guide is in the following locations: • 1989-92 engines: mounted to the firewall • 1993-96 2.5L engines: mounted on the thermostat housing in front of the coolant temperature sensor • 1993-96 V6 and V8 LDC engines: mounted to a bracket bolted to the right engine cylinder head • 1993-96 5.9L HDC engines: mounted to a bracket bolted to the air injection pump (AIR pump) mounting bracket. Fig. 2: Ignition coil mounting-all 1989-92 models Fig. 3: Ignition coil wiring and mounting hardware-1993- 96 2.5L engine 1. Inspect the ignition coil for arcing while the engine is running. If the engine will not start, this can be performed while the engine is cranked by either an assistant or a remote starter. Look at the coil in dim or low light to aid visibility of any arcing. Fig. 4: Ignition coil mounting-1993-96 3.9L and 5.2L/5.9L LDC engines 2. Arcing at the tower will carbonize the wire boot, which, if it is connected to a new ignition coil, will cause the coil to fail. In such cases, clean all the carbonization away or replace the components as necessary. Fig. 5: Ignition coil mounting-1993-96 5.9L HDC engine 3. Using a coil tester or ohmmeter according to the manufacturer’s instructions, test the primary and secondary resistance. Replace any coil that does not meet the specifications indicated in the accompanying chart. 4. Inspect the secondary coil wire for any sign of damage. Replace if any damage is found. Carbon tracking on the old wire can cause arcing and the failure of a new ignition coil. REMOVAL & INSTALLATION 1989-92 Models See Figures 6 and 7 1. Disconnect the negative battery cable. 2. Disconnect the three wires from the coil. Mark them to identify for installation. Fig. 6: Remove the coil bracket bolt at the cowl Fig. 7: Unscrew the coil mounting hardware, then remove the coil from the vehicle 3. Unplug the condenser suppressor connector from the coil, if equipped. 4. Unbolt and remove the coil. To install: 5. Bolt down the coil with old bolts. 6. Connect wires to coil making sure that the proper wires are connected where they should be. 7. Connect the condenser suppressor, if equipped. 8. Connect the battery negative cable Removal and Installation V6 AND V8 ENGINES 1. Disconnect the negative battery cable. 2. Disconnect the primary wiring from the ignition coil. 3. Disconnect the secondary spark plug wire from the coil. 4. Remove the two bolts and withdraw the coil from its mounting bracket. To install:
5. Position the coil on its bracket and install the two bolts. Tighten them to 100 inch lbs. (11 Nm). If the bracket has been tapped for coil mounting bolts, these fasteners require less torque, so tighten them to 50 inch lbs. (5 Nm). 6. Connect all wiring to the ignition coil. TESTING See Figure 1 The only test you can perform without a DRBII scan tool, or equivalent, is a basic check of the sensor only.

1. Observe the Misfire Current Counters parameter with a scan tool, in order to determine the affected cylinder(s). 2. Remove the air cleaner resonator and outlet duct. Refer to Air Cleaner Resonator and Outlet Duct Replacement in SI. 3. Disconnect the engine wiring harness electrical connectors from the affected ignition coil(s). Refer to Ignition Coil Replacement in SI. 4. Remove the ignition coil bolt(s) and ignition coil(s) from the camshaft cover. Refer to Ignition Coil Replacement in SI. Note: If water is observed in ANY of the spark plug recess areas, then it will be necessary to apply Loctite® 565 PST Thread Sealant* to ALL of the ignition coil bolt hole vents and bolt threads. 5. Inspect for water intrusion in the spark plug recess areas. Warning: Wear safety glasses when using compressed air, as flying dirt particles may cause eye injury. 6. If any water is present, then remove the water from the spark plug recess areas with low pressure air. 7. Remove the affected spark plug(s) from the cylinder head. Refer to Spark Plug Replacement in SI. 8. Replace ONLY the affected spark plug(s) with new spark plug(s) as needed into the cylinder head. Refer to Spark Plug Replacement in SI. 9. Fill the bottom of the ignition coil bolt hole vent with Loctite® 565 PST Thread Sealant* as indicated in the illustration, and apply it to the ignition coil bolt threads also. 10. Replace ONLY the affected ignition coil(s) with new ignition coil(s) as needed. Refer to Ignition Coil Replacement in SI. 11. Connect the engine wiring harness electrical connectors to the ignition coil(s). Refer to Ignition Coil Replacement in SI. 12. Replace the air cleaner resonator and outlet duct. Refer to Air Cleaner Resonator and Outlet Duct Replacement in SI. 13. Clear the DTCs with a scan tool.

Action Taken When the DTC Sets Conditions for Clearing the MIL/DTC Diagnostic Aids Test Description The numbers below refer to the step numbers on the diagnostic table. 2. This step verifies that the PCM is receiving a signal from the vehicle speed sensor. 3. This step verifies that there are no opens in the circuitry from the vehicle speed sensor to the PCM connector. 7. This step performs a resistance test on the VSS circuits from the PCM connector. • The transmission defaults to 3rd gear. • The PCM inhibits TCC operation. • The PCM illuminates the Malfunction Indicator Lamp (MIL). • The PCM turns OFF the MIL after three consecutive ignition cycles without a failure reported. • A scan tool can clear the DTC from the PCM history. The PCM clears the DTC from the PCM history if the vehicle completes 40 warm-up cycles without a failure reported. • The PCM cancels the DTC default actions when the fault no longer exists and the ignition is OFF long enough in order to power down the PCM. • Check for PRNDL DTC P0705. DTC P0705 affects transmission operation. This may set DTC P0502 falsely. • Check for Electromagnetic Interference (EMI) in circuits 400 and 401. EMI may be induced if the harness is routed along the spark plug wires. • Inspect the wiring for poor electrical connections at the PCM. Inspect the wiring at the TCC brake switch. Look for the following conditions: – A bent terminal – A backed out terminal – A damaged terminal – Poor terminal tension – A chafed wire – A broken wire inside the insulation • When diagnosing for an intermittent short or open condition, massage the wiring harness while watching the test equipment for a change. • Ensure that the VSS is securely tightened to the case extension.
