Ignition Coil: Testing and Inspection

IGNITION COIL INSPECTION [MZR 1.5]

Ignition Coil Inspection

1. Perform the spark test and identify the malfunctioning cylinder.

2. Replace the ignition coil of the malfunctioning cylinder with that of a normal cylinder, and perform the spark test again.

- If the spark is not normal due to a malfunctioning ignition coil, replace that ignition coil.
- It is unlikely that all four ignition coils fail to operate properly. To prevent replacing a normal component, perform the above procedure, identify the malfunctioning ignition coil, and replace it.

Ignition Coil With Built-in Power Switch Inspection

1. Disconnect the negative battery cable.

CAUTION:
- Removing the fresh-air duct from the air cleaner case may damage the fresh-air duct. Remove the fresh-air duct and the air cleaner case as a single unit except when the fresh-air duct is to be replaced with a new one.

2. Remove the fresh-air duct and air cleaner as a single unit. Service and Repair

3. Disconnect the ignition coil connector.

4. Measure the resistance between each terminal on the ignition coil connector using an analog circuit tester.






- If the measurement corresponds to the table, replace the ignition coil.
