4.1. Check component Y62y1 (Fuel injector cylinder 1).
Safety note
Warning!Risk of explosion, poisoning and injury!Fuels are highly inflammable and toxic if inhaled. Fuels may cause skin damage. fuel vapors are
explosive, invisible and spread out at floor level, they are toxic if inhaled and produce giddiness and an anaesthetizing effect.Rules of conduct and
protective measures
- Wear suitable protective clothing.
- Pay attention to national safety precautions and regulations.
- No fire, sparks, naked flames and smoking.
- Ensure the work place is adequately ventilated.
- Never drain or pour in fuels over assembly pits.
- Store drained fuel in a suitable and sealed vessel.
- Immediately eliminate any fuel which has flowed out.
First-aid measures
- Clean moistened skin with water and soap.
- Change moistened clothing as quickly as possible.
- If fuel gets into your eyes, rinse out your eyes immediately with water and contact a doctor if necessary.
Test 4.1.1: Test actuation of component Y62y1 (Fuel injector cylinder 1).
Test 4.1.2: Test signal voltage of component Y62y1 (Fuel injector cylinder 1).
Test 4.1.3: Check internal resistance of component Y62y1 (Fuel injector cylinder 1).
Test 4.1.4: Inspect component Y62y1 (Fuel injector cylinder 1) for leaks.
