System of onboard diagnostics (with self-diagnostics function)

The module of management of an immobilizer and ECM/PCM modules find malfunctions which can arise on the site including the following parts at included ignition.

ECM/PCM modules:

  • ECM/module code of management of an immobilizer
  • Consecutive chain of data transmission
  • ECM/PCM

Module of management of an immobilizer:

  • Transmitter code
  • Frame aerial
  • ECM/module code of management of an immobilizer
  • Consecutive chain of data transmission
  • Module of management of an immobilizer
  • Ignition signal

Vehicle with the diagnostic socket

At not earthed plug of the switch of the diagnostic socket for ECM/PCM and the included ignition (but at the stopped engine) and irrespective of a condition of electronic system of injection of fuel, the lamp of the indicator of malfunctions blinks, if ECM/PCM defines malfunctions in a control system of an immobilizer.

The lamp of the indicator of malfunctions burns: malfunctions in a control system of an immobilizer are not found.

The lamp of the indicator of malfunctions blinks: ECM/PCM modules or the module of management of an immobilizer revealed malfunctions in a control system of an immobilizer.


As soon as ignition joins, ECM/PCM modules and the module of management of an immobilizer reveal existence of malfunctions in a control system of an immobilizer. After completion of diagnostics the lamp of the indicator of malfunctions continues to burn. If diagnostics reveals any violations (result of "abnormal"), the lamp starts to blink at once. And if diagnostics does not reveal malfunctions (result of "normal"), the lamp continues to burn. This diagnostics needs at most 3 seconds.

Vehicle without the diagnostic socket

At the included ignition (but at the stopped engine), irrespective of a condition of electronic system of injection of fuel, the lamp of the indicator of malfunctions blinks, if ECM/PCM defines malfunctions in a control system of an immobilizer.

The lamp of the indicator of an immobilizer burns: in a control system of an immobilizer it is not revealed malfunctions.

The lamp of the indicator of an immobilizer blinks: ECM/PCM modules or the module of management of an immobilizer revealed malfunctions in a control system of an immobilizer.

And if diagnostics does not reveal malfunctions (result of "normal"), the lamp continues to burn. This diagnostics needs at most 3 seconds.

When ECM/PCM modules and the module of management of an immobilizer reveal malfunctions on the above-named sites, in memory of the module of management of an immobilizer the corresponding diagnostic code of malfunctions (DTC) remains.

The diagnostic codes of malfunctions which are storing in memory of each controler (ECM/PCM modules and the module of management of an immobilizer).
