• Although measured values are different for each
ignition coil, they are normal as long as voltage is
higher than the specified value.
If the peak voltage is lower than the standard value,
follow the checks described in the troubleshooting table
(page 5-3).
Install the removed parts in the reverse order of

• Check the cylinder compression and check that the
spark plugs are installed correctly in the cylinder
