Hood: Service Precautions

DANGER!:

WARNING: Persons with heart pacemakers should never perform work on the ignition system.

Electronic ignition systems operate in a dangerously high voltage range on the low voltage side (primary circuit) as well as on the high voltage side (spark circuit). Due to the high voltages in electronic ignition systems contact with parts or terminals under power can be lethal!

Always switch off the ignition when working on the ignition system, e.g.:
- Replacing ignition system components
- Connecting engine test instruments
- Connecting removed assemblies for testing on test benches

If it is necessary to switch on the ignition for work on the ignition system, dangerous high voltage is present in the entire ignition system.

Never install intermediate pieces or built-in sensors with bare metal outer surfaces in the ignition lines.
