Replacing component
| CAUTION | Avoid touching the pins in the control module and the corresponding connector on the cable harness. There is a risk of static discharge which could damage the control module. Discharge yourself and tools to be used by holding the tool's metal part and touching a body part on the car just before starting to work. |
Check the connectors to the ignition coil and Engine Control Module (ECM) for damage to pins and connections as well as for oxidation and contact resistance.
Check the voltage supply cable to the ignition coil's connector #4. The voltage must be battery voltage with the ignition on (ignition position II).
Check the ground cable between the ignition coil's connector #3 and ground connection. Check the cable for open circuit and short-circuit to voltage.
If no malfunction is found
Try a new ignition coil.
