IMPORTANT
Before diagnosing a problem vehicle and attempting to perform an emergency
regeneration, it is important to obtain a full diagnostic log and read out relevant
measured value blocks.
NOTE
1. The DPF will not regenerate if the engine management light is on, or there
is a faulty EGR valve.
2. The ECU must be re-adapted when replacing the DPF and when topping
up the fuel additive Eolys.
3. If the vehicle needs to be driven in order to perform a DPF service,
ALWAYS have a second person help you. One person should drive the
vehicle while the other person observes the screen on the Tool. Trying to
drive and observe the Scan Tool at the same time is dangerous, and could
cause a serious traffic accident.
Immobilizer (IMMO) Service
An immobilizer is an anti-theft mechanism that prevents an automobile’s engine
from starting unless the correct ignition key or other device is present. This
device prevents thieves from starting the car by a method known as hot wiring.
Most new vehicles have an immobilizer as standard equipment. An important
advantage of this system is that it doesn’t require the car owner to activate it; it
operates automatically. An immobilizer is considered as providing much more
effective anti-theft protection than an audible alarm alone; many auto insurance
companies offer lower rates for vehicles that are equipped with them.
As an anti-theft device, an immobilizer disables one of the systems needed to
start a car's engine, usually the fuel supply or the ignition. This is accomplished
by radio frequency identification between a transponder in the ignition key and
a device called a radio frequency reader in the steering column. When the key
is placed in the ignition, the transponder sends a signal with a unique
identification code to the reader, which relays it to a receiver in the vehicle's
computer control module. If the code is correct, the computer allows the fuel
supply and ignition systems to operate and start the car. If the code is incorrect
or absent, the computer disables the system, and the car will be unable to start
until the correct key is placed in the ignition.
The IMMO service enables you to disable the lost vehicle keys and program
the replacement key fob. It could be one replacement key fob or more,
depending on your needs.
