Vehicle Damage Warnings

Safety precautions
To prevent injuries to persons and/or damage to the fuel injection and ignition system, observe the following:

CAUTION: When performing repair work, especially due to the confined conditions in the engine compartment, pay attention to the following:
^ Route all types of lines (e.g. for fuel, hydraulics, EVAP system, coolant, refrigerant, brake fluid and vacuum) as well as electrical wiring so that the original positions are restored.
^ Ensure sufficient clearance to all moving or hot components.

- Do not touch or disconnect ignition wiring when the engine is running or being turned at starter speed.
- If the engine is to be turned at starter speed without starting, the ignition must be switched off before connecting or disconnecting injection or ignition system wiring or tester cables.





Engines: AVH, AZG, BBW, BEV

- Disconnect black 6-pin connector from ignition coil with final output stage (arrow).






Continue for all engines

- Remove fuse 32.

Note: Removing fuse 32 interrupts the voltage supply to the injectors.

Engines: APK, AQY: Fuse No. 28 for fuel pump
Observe the following if test and measuring instruments are required during a road test:
^ Test and measuring instruments must be secured to rear seat and operated by an assistant from this location.
If test and measuring instruments are operated from front passenger's seat and the vehicle is involved in an accident, there is a possibility that the person sitting in this seat may receive serious injuries when the airbag is triggered.
- Erase engine control module Diagnostic Trouble Code (DTC) memory on completion of work, this will remove any DTCs stored in the memory caused when removing the fuse.
- Generate readiness code again in "Guided fault finding" after erasing the DTC memory.,Refer to Adapting components and functions.
