Checking the engine
WARNING:
The ignition system operates at high voltages. Contact with the high tension circuit components, such as ignition coils and spark plug caps, is dangerous.
CAUTION:
When fault-tracing the ignition coils, the corresponding injectors must be disconnected. This is to protect the three-way catalytic converter (TWC).
- Start the engine.
