1. Turn the Ignition Switch "OFF".
2. Disconnect the 4 P Connector and Ignition Coil Wire.
3. Using an Ohmmeter, measure resistance between the Terminals. Replace the Coil if the resistance is not within specifications.
NOTE: Resistance will vary with the Coil temperature; specifications are at 68°F (2O°C).
Primary Winding Resistance (Between the No. 1 and No. 3 Terminals): 0.6 - 0.8 ohms.
Secondary Winding Resistance (Between the No.1 and Secondary Winding Terminals): 14 - 22 K Ohms.
4. Check for continuity between the No. 1 and No. 2 Terminals. Replace the Coil if there is no continuity.

When to See a Mechanic
Stop DIY work and contact a certified mechanic immediately if any of the following apply:
- • You smell fuel, burning insulation, or see smoke.
- • Brakes feel soft, pull hard to one side, or make grinding noises.
- • The engine overheats, stalls repeatedly, or misfires under load.
- • You are missing required tools, torque specs, or safe lifting equipment.
- • You are not confident in the next step or safety outcome.
