Safety measures at diagnostics of malfunctions

Before check of the diagnostic information (codes of malfunctions (DTC), the data of a framework of freezing, etc.), being in memory of the electronic block of management (PCM), do not disconnect сцепки from the electronic block of management (PCM (ECM)), a cable of the battery from the battery, wires of grounding of the electronic block of management (PCM) from the engine or the main fuse. Such switching-off will erase stored in memory of the electronic block of management (РСМ) the information.

At the car without a socket for the monitor it is possible to check up or erase the diagnostic information stored in memory of the electronic block of management (РСМ), by means of scanning tool SUZUKI (Tech-1) or the universal scanning tool. Prior to the beginning of work with the scanning tool attentively study the instruction on its operation that it is good to understand its functions and application.

Sequence order at diagnostics of malfunctions (only for the car without a socket for the monitor):

If in memory there are two or more codes of malfunctions (DTC), find in the table of codes of malfunctions (DTC) that code which has been found out by system the first, and follow the instructions specified in the table.

If no instructions are present, eliminate malfunctions of the specified codes in the following sequence:

  • Any codes of malfunction (DTC), except codes P 0171/P 0172 (fuel system too poor \too rich) and code P 0400 (malfunction in system recycling the fulfilled gases (EGR)).
  • Codes of malfunction P 0171/P 0172 (Fuel system too poor \too rich) and code P 0400 (malfunction in system recycling the fulfilled gases (EGR)).

Before check read in the Head the General information Safety measure Section at service of electric chains and observe them at work.

Replacement of the electronic block of management (РСМ)

At replacement of the serviceable electronic block of management (PCM), check up the following:

The neglect such check can lead to damage serviceable PCM.

  • Resistance on all relays and drives corresponds to the specified values.
  • The gauge of weight of air (MAF), the pressure gauge in the inlet pipeline (MDP), the gauge of position of a throttle (TP) and the pressure gauge in a fuel tank are in a good condition, and a power chain of these gauges are not closed накоротко on grounding.
