Please check the focus of this article below: Autel MaxiSys MS908S Pro Special Functions User Guide: DPF & IMMO Service
1.Diesel Particle Filter (DPF) Service
The Diesel Particle Filter (DPF) function manages DPF regeneration, DPF component replacement teach-in and DPF teach-in after replacing the engine control unit.
The ECM monitors driving style and selects a suitable time to employ regeneration. Cars driven a lot at idling speed and low load will attempt to regenerate earlier than cars driven more with higher load and speed. In order for regeneration to take place, a prolonged high exhaust temperature must be obtained.
In the event of the car being driven in such a way that regeneration is not possible, i.e., frequent short journeys, a diagnostic trouble code will eventually be registered in addition to the DPF light and “Check Engine” indicators displaying. A service regeneration can be requested in the workshop using the diagnostic tool.
Before performing a forced DPF regeneration using the tool, check the following items:
<1>The fuel light is not on.
<2>No DPF-relevant faults are stored in system.
<3>The vehicle has the specified engine oil.
<4>The oil for diesel is not contaminated.
Important Message:
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.
Please have your attention here:
<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, a second person is needed for the function. One person should drive the vehicle while the other person observes the screen on the Tool. Do not attempt to drive and observe the scan tool at the same time. This is dangerous and puts your life and the lives of other motors and pedestrians at risk.
2.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 an immobilizer.
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 can disable a lost vehicle key and program the replacement key fob. One or more replacement key fobs can be programmed.
