must be checked and replaced in accordance with
the following standards:
IAfter faulty parts are replaced, the warning light
operation must be checked.
IWhen the ignition switch is turned ON, it lights
up for about 7 seconds and then it goes out for at
least 30 seconds.
IThe trouble code stored in memory must be
erased after the check.
