Test 1: Check component T1/x (ignition coil(s)).
1. Check component T1/x (ignition coil(s)).
Test 1.1: Check component T1/4 (ignition coil cylinder 4).
1.1. Check component T1/4 (ignition coil cylinder 4).
Warning!Hazard as a result of high voltage at the ignition system!
- Electronic ignition systems operate within a hazardous power range both at the low voltage side (primary circuit) as well as on the high
voltage side (secondary circuit).
- Contacts with such parts can result in burns, heart flutter or cardiac arrest.
Rules of conduct and protective measures
- Persons with heart pacemakers must not perform any work on the ignition system.
- Switch off the ignition when performing work on the ignition system.
- Do not touch any parts of the ignition system when starting the engine or when the engine is running.
- Wear protective shoes with rubber soles.
- Do not install any uninsulated adapters into the ignition cables.
