Fuel Injection System

Safety Precautions

CAUTION!
When doing any repair work, especially in the engine compartment, pay attention to the following due to clearance issues:

• Route lines of all types (e.g. for fuel, hydraulic, additive, coolant and refrigerant, brake fluid, vacuum) and electrical wiring so that the original path is followed.

• To prevent damages to the lines, make sure there is sufficient clearance to all moving or hot components.

Observe the following if test and measuring instruments are required during a test drive:

• Test and measuring instruments must be secured to rear seat and operated by a 2nd person from this location.

If test and measuring instruments are operated from the 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.

CAUTION!
Secure Scan Tool (ST) on the rear seat and operate it from there by second technician.

To reduce the risk of personal injury and/or damage to the fuel injection and glow plug system, always observe the following:

• Only disconnect and reconnect wires for glow plug and fuel injection systems, including test leads, when ignition is turned off.

• Obtain radio code for radios with anti theft coding before disconnecting battery.

• The battery must only be disconnected and connected with the ignition switched off, otherwise the Engine Control Modules (ECM) could be damaged.
