Power Distribution Relay: Service Precautions

Hazard from high voltage of ignition system
Electronic ignition systems operate within a hazardous power range both on the low voltage side (primary circuit) as well as on the high voltage side (secondary circuit). Contact with such components can result in burns, heart flutter or cardiac arrest.

Rules of conduct/precautionary measures
- Persons with heart pacemakers must not carry out any work on the ignition system.
- Switch off ignition before carrying out any work on the ignition system.
- When working on the engine when it is running or rotating at starter speed, do not touch or remove any components of the Ignition system.
- Wear safety shoes (with rubber soles).
- Unplug crankshaft position sensor connector at the control module or at position sensor.
- Do not install any electric conducting, uninsulated adapters or sensors into the ignition cable.
