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 i n 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,
